Hello "Daniel L. Stripes"

I have used a Catweasel in a towered A1200 for almost a year now. I had no
problems with the software and it reads several formats of Amiga and PC
disks, and I suppose I could set it to access more if I needed. I use it
mainly for downloading files at work and taking them home on 1.44Mb disks
which is much more convenient that the 720k ones :-)

I have had two problems neither really to do with the Catweasel, at first
it would not read High Density floppoes at all. I traced it down to the
badly made Sony PC drive, the sensor was not lined up with the hole in HD
floppy disks, so I resoldered it and it worked.

In a towered A1200 it is dufficult to see the motherboard behind stuff and
I plugged the CW into the clock port incorrectly and the cable fried, you
can also connect it via the IDE interface which I have it on now and it
still works OK thankfully.

A couple of tips, if you use it as a df0: replacement, you do not need to
use the silly names for drives that the software gives them.

In your s-s at the beginning of the assigns then add the line

assign df0: dismount

Rename the catweasel Amga unit 0 drive in your Devs:dosdrivers to df0:

"Daniel L. Stripes" <dstripes@...

It should be the same.

There is also another tip as well if you have removed the original df0:
It is not that important but speeds up the boot up as the system is not
checking for a nonexistent drive. You need to put a diode between two pins
across the floppy drive and the drive then does not get checked, also if
you do not re-assigned df0: it prevents a non-dos disk appearing on the WB.

If you remind me I will find out which two pins and which way the diode
goes, I am at work now so cannot check.

This is just a copy of a note I sent to Jens. Maybe someone here has already
had this answered.

I was told this list is also about the a3k and Buddha controller.

I'm using:
A3k, Buddha (ROM FLASH seemed to work this time.), IBM Deskstar 10.1 gig.

filesystem 44.5 (the 100 megger, I can't install the 44.5 on it. Have no idea
why) It's still 40.1..

Here's the bug..
Browsing Awebs cache, I was saving some stuff from the cache to a directory
I'd been using up to 17 megs (in just this one directory, there were maybe
100 megs total on this partition now). While saving, I noticed in the DIR
viewer that there were some out of place pix. Finished saving from aweb,
dropped out of aweb, went in search of the sub/sub directory where the out of
place files were last seen.

Only thing I could find of the directory I'd just saved to in a sub directory
of it was the directory info file.

Ran disksalv for undelete. I know disksalv has no idea what to do above
4 gigs.

Everything else I found on aminet, just froze, or couldn't even find the
drive. Anyways disksalv did work for undelete. But it also showed me the
directory I was looking for had moved, not been deleted.

the dir was like this..
root/sub/sub Before I quit aweb.
After disksalv I actually found the original directory (intact) as
Root/sub/another dir/sub/sub/sub

It had appended itself to a secondary sub directory.

Depending on your eyesight..

When I put my CD on the a3k I had exactly the same trouble. Installed amicdfs.
And use the CD0 mount vs any specific CD.

The eyesight problem was the terminator pack. I can't recall if there were any
good diagrams with the CD to tell me what goes where, plus I have a 2nd hand
amiga, so all the books I have I got from swap meets. Have no idea if I have
original books.

So where the eyesight came in was when I called softhut back to get a word for
word description of how to set the CD up, they mentioned the terminator packs
on the back (was it the CD or the amiga ? I think the CD Yeah it was internal
in the CD) The terminators are EXTREMELY SMALL. Almost invisible, and where
mine were located (on a pioneer CD) they were even harder to see as they were
partially recessed. So I couldn't even FEEL them... Finally got out the
Halogens and the microscope and found the terminators in place. Had to fiddle
with them to get them correct.

Best I can offer. If you can't see a fly at 50 feet, you might consider a
microsope and halogens..

Also I found that with asimcdfs uninstalled, if I just used the stock CD0 from
Commodore, that worked just fine also, but had asimcdfs, so I use it..

This is just a FWIW:
My setup:
A3k, 18 megs ram, Buddha, Pioneer 12x CD player.

I went and got the Buddha controller. No complaints I can think of with this,
it's working well with my 2.1 gig WD Caviar. (This is maybe a year old version
) Note# The docs recommend against the WD Caviars

The docs are old, older than the WD drive I installed...

History as to why I went this route..

I had a SCSI drive eaten by this a3k (a quantum 1.3 gig)..

So with the errors I was getting with HDTools, (scsi error #2, or something to
that effect), I caught a note that someone had installed an IDE drive on an
a3k... Great; bigger, cheaper drives and keeping up with technology. Not a SCSI
avail locally. Have to mail order to get one...

Ok Jens recommended the IBM DTTA drives since it's the drives he's
using (most likley older than the 10.1 gig Deskstar I ordered).. The new
deskstars have some special things in them that may be just that much ahead of
the Buddha, I got the drive to run (off and on) over a period of 2 weeks.
When it gurue,d the odds were real good it might not come back for hours..

Last time it gurued it didn't come back at all.

I moved it over to the PC. The new IBM Deskstars are even too cutting edge for
my 386 AT PC. It works on the PC (8 gigs of it) using disk manager 707 to fool
the 386 into thinking there's 4 2 gig drives attached. (which is why it
doesn't show the additional 2 gigs.) A 386 or the software was never meant to
see that much space.

Anyways the Deskstar runs on the PC. I tried once more today, now that I got
both machines partially setup, to see if I could get the 10gig to work here on
the ami..

It wouldn't even boot. Worked just like it did when I removed it to the PC..
Final GURU took it out of commision..

So I'd say if you want a huge IDE drive on your a3k using a Buddha, stay away
from the VERY NEW IBM's.. I can't explain why it booted off and on for 2 weeks
intermittantly and now won't boot at all from the ami. ust that you shouldn't
expect much if you do get a brandnew IBM deskstar to put on your a3k...

As for what brand or version drives, I'd say ask Jens what kind he has in his
test bed a3k, and what year make/model it is... I went with his recommendation
for the IBM DTTA drives. They're just way too new and cutting edge I suspect
as the amiga or the Buddha can't handle the new IBM drives..

Then again anything could have happened to the Buddha during the flashing or
what have you.. Who knows..

Worked off and on for 2 weeks, and now won't work at all..
| 25|25|1999-04-05 00:06:03|mikec@popstar.com|Hello|
Good evening. I've just joined the list.

I was just reading the archives and I'm surprised by the problems some of you have been having. I have a 4000T (used to use a dodgy A3K) with a Zorro Catweasel, and have had no problems whatsoever.

Well actually, that's a lie. Sometimes my RDB gets deleted and I haven't found a cause yet. It was very scary at first because I though I'd lost everything, but it's actually easily recoverable. It's very annoying though as the 4000T has only got one floppy power connector (!) so I have to open it up every time.

I think the Catweasel/Buddha is superb. Of course, I've been waiting for the Hypercom 3+ for what must be 2 years now, but apart from that I'm very happy with it.

BTW, someone mentioned remounting one of the Catweasel drives as DF0:. Well if you get MFS from Aminet, you can remount *all* of your Catweasel drives as DF0:.

Hi Mike,

mikec@... wrote:

Catweasel drives as DF0:.

That was me :)

I only have one HD floppy connected to the Catweasel, but if I had more
wouldn't it be rather confusing to have them using the same name ?

Or do you mean I could set the current DF0:, PC0: and DH0: (HD disk)
all to use DF0: rather than have different names - now that may be useful.

One problem I can foresee though is if I format DF0: would it be an
Amiga disk a PC 720k or PC 1.44Mb disk ?


| 27|25|1999-04-05 13:36:09|Mike Clarke|Re: Hello|

I do indeed mean the latter. MFS works as a sort of virtual drive handler.
It auto detects the type of disk you put in and DF0: becomes the device for
that disk.

You get a patch the format command which lets you specify what type of disk
you want to format. However, this won't work with DOpus5 (unless you use the
Shell format command via a menu or something). In that case, you merely open
the MFS commodity and tell it what type of disk the disk in the drive should

Get it from http://uk.aminet.org/pub/aminet/disk/misc/mfs21.lha

It's only 21k.

Hello everyone on the list,

first of all: I`m using the buddha in my A4000T.
I bought it because I thought my IDE-HD (6GB Seagate) would be faster with
it and would need less CPU-time.

Now I know this is wrong (and after reading the archive I know other peaople
thought the same)-:

Is there no way to make things faster?

Another question: has anyone experience with the clockport of the buddha?
Does it need special devices or can I plug every A1200 "clockport-device"
onto it and it works without special buddha-software (even the new
clockport-expander from RBM)?
And how is performance with this port?

buddha with an a3k ?

I really shouldn't say it ate 3 drives. The 1st drive the SCSI seemed to die
of it's own before I even go the buddha.

Got a 10 gig IBM. Along with the 2 weeks of trying to get it up and running,
it did work (for awhile and a little bit at top range 10 gigs).

Tried installing the Western Digital (I know there's a warning on it, but it
did work "The longest maybe 3 months"). Tried some pocket 210 meg from my 386
no brand name I could find, Buddha couldn't even see it.. So that went no

Now have a 3.x gig Fujitsu. This one wanted to play hide and seek for the
entire morning.

Boot, drives missing
HDTOOLS reinstall and format sectors
Boot, drives missing and now hdtools scrambles the name
HDTOOLS reinstall and format sectors
Boot, drives missing.

Finally think I fixed this trouble, but in the process the WD got eaten
alive.. Thought I'd go with 2 IDE hd's. vs a SCSI and an IDE...

Anyways the hide and seek (fingers crossed), for some reason, the buddha board
was listed as missing in action and there wasn't any board diagnostics until I
used the two mice buttons to see what it was doing.
Boot once finally drive is there, format it.
2 mice down, board missing in action.
power off wiggle buddha
boards visible again, no bad sectors, (bad sectors hitting constantly).
Now after finding the board was wiggling itself loose, it finally allowed me
to copy the setup to the big drive.

Now the WD 2.1 gig came off the 386 where it lived quite nicely for over 2

Had to install the IBM to the 386 when the ami quit seeing the IBM drive.
It saw the IBM maybe 2 weeks, then just quit.

Put it on the 386, (this machine can only use 8 of the 10 gigs cripes...) and
so far it would seem it's working just fine there.

The Fijitsu (new 1 day) I really have no idea if it's the drive, or if the
Buddha has just decided it's time to try something else annoying.

I would ask if ya think this is why there were so many converts to PC's ? Cept
I own a PC, and I still prefer this amiga. PC's have just as many troubles,
and are even harder to fix...

Is anyone else using a buddha on an a3k and having similar troubles ?

Oh yeah is there a max limit for FFS ? vs the FFS That is designed for the
HUGE GIG drives over 4 gigs ?

I also had the FFS 44.5 installed awhile there. Took 9 hours just to find out
the NEW HDTOOLS proggram when attempting to install FFS wasn't bothering to
check the version agains the DOS type V44.5 goes with DOS/3. Took me 9 hours
to see it wasn't changing that DOS/1 to DOS/3. Even though the only FFS on
the drive was 44.5 the version command via CLI on every drive reported 40.1.

Hello Alfred
Isn't the Catweasel just meant for connecting other types of floppy drive ?
I think I would be #very# pleased if I got 2Mb/s out of my DF0: :o)

Of course I meant the IDE part of the Catweasel Z2; but it would be also
very interesting if someone has such transfers with a disk drive :)

Not all, but most (A500(+), A2000, A1000 do not have IDE interfaces).
But I bought the buddha because the internal interface eats all CPU time and
is to slow; I did`t thought the buddha would be the same...

I have had both a Squirrel and now a Blizzard SCSI interface. Iuse that for
my CD Rom, Zip drive and scanner. I like SCSI except for the way the

The nice thing about IDE with a 1200 is the drivers are in the Rom but SCSI
has to be mounted at boot up.

It's nice to have access to both though :-)

Here's a simple question:

Anyone with the following hardware:

A3000 Desktop (the only Amiga I know that definitely has problems)
Catweasel/Buddha Z2 (first version with EPROM)
CyberStorm MK3 or PPC

And if you have, can you get your machine to boot, (at all), with the
CW/Buddha BootROM installed?

If you answered 'Yes' to the last question, what's your secret?

the Clock port but that got a bit stuffed a while ago, a lot of smoke

G'day folks,

I am new to this list and need some advice/help.

I have just purchased a Ricoh MP7120A 12x10x32 CD-R/RW CD Burner and have it
connected to the second header on my CW Z2 Mk2 board as scsi.device unit 5.

I have it installed in an Amiga 2000-060@60, 2+132meg ram, OS3.9.

The problem is that the Ricoh is not being detected on the board after a
software reset, either by setpatch or a system crash.

I have a 13G HD as unit 0 and I boot the system from this drive and all is
fine if I reboot the computer via the keyboard but the Ricoh will not be
found if I don't do this.

If I connect another HD to the same cable at the Ricoh, it is detected as unit
4 and is available after the system has booted but not the Ricoh. Even
finddevice does not see it after a software reset.

I have talked to Jens about this and he suggested that I have a look at
IDEFix97 but the prefs only go up to unit 3 and the second header is addressed
as units 4&5. :(

Does anyone have any suggestions as to best attack this problem?

Been thinking about buying a Buddha card for my Amiga 2000, which is still running 1.3 WB. I've seen in several places now that I will need to format the new drive using HDToolbox in Workbench. This will be my first experience installing an IDE drive into an ECA Amiga, and I can't seem to find any sort of HDToolbox function in Workbench 1.3. I'm assuming that version of HDToolbox from my 1200 won't work on the 2000. Or perhaps I'm wrong?

I'm probably overlooking something quite obvious- can someone please point me in the right direction?

Hi!. I'm a Spammer! hehe.. Nah just kidding.

I am really pleased to see your efforts in opening this group again!.

I am a new Catweasel owner. I have had my Catweasel MK4 Plus now only
a couple of weeks.

I have 5.25 & 3.5 inch HD drives on mine.

I haven't yet come across any SID's clean enough to be worthy of
fitting to the board, but I will keep my eye's open.

I only just managed to get my Catweasel actually as after the market
crash our dollar dropped rather fast unfortunately.

I ended up paying some AUD$180 for mine including freight. Far too
expensive. But yet I have been planning for years to buy one so I am
very happy regardless.

I would also like to buy a second Catweasel, but with the current
increase of price and further drop of the exchange rate it works out
to some AUD$225+ now including postage. Far far out of reach
unfortunately. But you never know things may change over the comming

The machine I have mine in is a AMD Dual core AM2 4000+.
I run Win XP Home / Sabayon (Gentoo) Linux dual boot.

I haven't installed anything on the linux side yet. BUt on the windows

I have read many C64 and Amiga disks already and have been very

Oh and to answer your question my Commodore collection consists of the

A3000, A1000, A600HD, A500, C64, & Vic-20.

On the C64 front there is another amazing peripheral coming called a
uIEC. It is a very inexpensive interface for the C64 and others that
plugs in the drive port and allows SD card, IDE hard drive, and
possibly soon RR-Net (ethernet) conectivity.

I hope to get an A1200HD one day. I have never got to play with AGA as
I left CBM a year before their demise unfortunately.

Hi All and welcome to the restored Catweasel mailing list!

First, I would like to thank Petter for reclaiming this mailing list
for the Catweasel community. This is a very good thing which will
benefit us all.

This is your normal mailing list and like any other it is what you make
of it. Since its been a while since there has been any Catweasel
related discussion please introduce yourselves.

My interest with Catweasel is regarding using it to read hard sector
minidisk format vintage/classic computers like NorthStar, Vector
Graphic, and Heath. Last year I wrote some programs for data recovery
for those platforms based on the Tim Mann Catweasel tools.

Please commence to discussing any Catweasel related topics. Thank you
and have a nice day!

I heard about this list from the cctalk mailing list. It's nice to
find a place specifically for this little gem. I have a Mk4 card,
which I hope to soon figure out how to get working under Linux. Based
on what I've discovered so far, it wouldn't be too farfetched to use a
Catweasel as a regular floppy interface without first going through
the onboard header. Comments? Advice?
| 269|268|2008-11-01 15:02:12|Andrew Lynch|Re: Catweasel as sole floppy interface|
--- In catweasel@yahoogroups.com, "David Griffith"

As to whether the CW4 could be the sole floppy interface, I think that
is possible. Many new PCs don't even include floppy drives anymore and
it probably won't be long before the FDCs disappear as well.

However, I don't think the CW4 by itself could be a boot device since
it does not have any onboard ROM (AFAIK) for booting.

That's my recollection and thoughts on the subject. Others?

Thanks and have a nice day!

Andrew Lynch

PS, the CW is a multiplatform device so if people would like to discuss
as particular application for it, please post a modest invitation in
places where CW owners are likely to gather. I posted invitations at
CCTALK, Vintage-Computer.com Forum, and cpm.os.comp which are the
places I frequent. I think there is a sizable Amiga CW community as
well and possibly Mac?

however, with a proper driver (the official driver doesn't, and will not,

| 274|274|2008-11-02 13:31:15|Ken|My Early experiences with Catweasel MK4 Plus|
Hi everyone.

Well so far I am totally wrapped with Catweasel.

Here are some of my experiences so far.

I use both 3.5" & 5.25" HD Drives.

When working with 5.25" aged disks constant cleaning becomes very
important. Many of the disks I have tried to archive have shed their
coatings. Some are so bad that the head has crashed and stalled the
drive to some degree like a bulldozer bucket skimming the ground. When
looking at the disk afterwards you can see dual crash marks in the
media surface.

One time I was very concerned that I had possibly broken the head away
after a bad disk crash, fortunately 3-4 long cleans later the drive
finally started reading again and has since been fine.

I am not sure whether this is from oxidation or shedding of the media
surface or both.

All my disks have been stored very well, but some date back 25+ years.

Media brand definitely plays a big part in this, but sometimes there
seems to be exceptions.

Anyhow, I have found that constant cleaning of the heads is utmost if
you are to get the most data possible from a disk. I have no idea on
whether this is detrimental for the drive heads but this seems to be
an unfortunate necessity when dealing with this old media.

When encountering errors during a read it's interesting to see that
even some 50 passes later there is the possibility of recovering data
still. I am not sure how the software does this but I am guessing the
latter passes are done in a different or progressive way.

I have also found that even with disks that shed or loose their
surface, if the drive is cleaned and the disk re-inserted often the
data can still be reclaimed, but this often takes several tries and re
cleaning of the drive.

I do also wonder about the possibility of removing the media from the
jacket and wiping it down with a soft cloth and some alcohol to remove
the oxidation etc in severe cases. I guess this would depend on how
important the data retrieval is for that disk.

In an ideal world one would not submit their drives to such horrible

And of course the big question is what is the life expectancy of a
drive given such treatment as 5.25" drives will become a finite
resource more and more as time goes by.

Some of the oldest disks I have recovered have been original Commodore
issue. I had for example a 3 set of 04/08/83 Dated Vic-20 Games,
Utils, & Demo's. To my surprise These remained perfect. Very shiny
media surfaces still and read 100% with no errors on the first pass. I
was very happy about this as I feel Vic software is even more precious
to preserve then the C64 even.

As for 3.5" media, life has been much easier. None of my collection to
date has shed or oxidized surface issues.
Whether this is due to less age (20+ years) or the protector slide or
better manufacturing I don't know.

So far all my Amiga disks have had a high success rate. When I do
encounter errors most do recover withing a few extra passes.

That said I have had some disks that don't recover 100%.

Cleaning the drive has rarely been needed for the 3.5" drive.

I hope people have found my post of interest. Feel free to comment.

My future plans include obtaining an 8", 100tpi 5.25", & 2.88mb 3.5"
drive mech's.

I am also very eager to see Apple IIe read / write support.

On this note can some one please mail the developers some original
Apple IIe format disks to work with. Currently they have none.

Hi All,
This is only semi-related to Catweasel but definitely related to
recovering data on vintage computers. Previously I had suggested to
the good people at Individual to incorporate a FDC into the Catweasel
design so as to allow some of the capabilities that David was referring
to in his earlier email.

One thing which would be a great compliment to the Catweasel would be a
PCI floppy controller. However, I have never seen such a thing. Does
anyone know where or if a PCI floppy controller is available?

I recall from earlier discussions on CCTALK that Dave Dunfield had
suggested a PC floppy controller project which I think but am not 100%
sure was PCI but based on the WD2797 controller. The project died in
its infancy in the familiar CCTALK fashion. What a shame.

There are PCI floppy controllers available at the chipset level but are
usually incorporated into the motherboard design. I have seen those
and have some datasheets. I wonder how difficult it would be to do a
PCI floppy controller?

Does anyone have any thoughts on the issue?

Thanks and have a nice day!

Hi Tim! Thanks! An FPGA solution would be cool and probably
compatible with how the Catweasel is already designed. It is
basically an FPGA already, right? I am not sure but that is the
impression I got.

Another approach would be to use an "off the shelf" Super IO
controller like this one


It is the same Super IO chip the P112 project uses on their board.
This chip appears to be ISA compliant but does not mention PCI.
There are other Super IO chips available for PCI. The PCI card would
not need all the features but just the FDC portion.

I am presently designing a Disk IO board (IDE & FDC) for the N8VEM
project. It is quite different than a PCI FDC but is broadly similar
in some ways. Instead of PCI the Disk IO board uses the ECB bus
(Z80) and instead of SMT uses through hole PCB technology only. The
components are all DIP and much lower technology than a PCI card
would be. A PCI FDC is way above my skill set but if someone had
experience in the topic it certainly would be useful.

Thanks and have a nice day!

Hi, I'm currently on a pilgrimage to find some SID chips for my

I don't really have any interest in the sound side of the device, but
I do want the joystick and keyboard ports to work completely.

It seems the SID chip is relied upon for this in some way.

Can anyone point me toward some really good software that will test
the SID totally in a Commodore 64 before it goes anywhere near my
beloved multi million dollar Catweasel?

Also is there any possibility that future firmware updates for
Catweasel will allow for full Joystick / keyboard support without
needing to use these old highly unstable and hard to get SID chips?

yes and no... the above listed things use one of the paddle input lines, and
paddle functionality is provided by the sid. without a sidchip there is no
paddle functionality (the catweasel doesnt have a/d converters).

unfortunately this is kinda hard to test - if you have paddles for the c64 you
can try using them with one of the games (eg arkanoid) that support them.
another possibility would be to try if a c64 mouse works

there already is support for using the 2nd mouse/joystick button without a
sid, but it only can work if those contain a proper pullup resistor at those
input lines, so the status of the line can be seen as a definitive "high"
and "low" - without it the catweasel (or any other device) can only see
a "low" when the button is pressed - and nothing definitive when the button
is not pressed (the switch will be "open" and the input line floating - which
will be interpreted as "low" too). there is not much the firmware could
change about it. however, you could add this pullup resistor to the
mouse/joystick you want to use - unfortunately very few already have them
(personally i found only one out of those i used for testing)

Looks like my best bet is not to install SID's as this is likely to upset the Joystick ports anyhow.

Thanks for the update. Much appreciated.
I have tried it and it seems to read the Apple disks ok. But For some reason I can't get get the emulator to run the disks.
I would try a disk on my Apple clone but Catweasel has no Apple IIe write ability yet.
The emulator I am using is called `AppleWin`.
Has anyone else had any luck yet?
Here is what AppleWin says about the disk format. I will post this incase someone finds it useful..

Disk images can be in a number of different formats, depending on how they were created.

DOS Order Images:

DOS order disk images contain the data from each sector, stored in the same order that DOS 3.3 numbers sectors. If you run a DOS program on the Apple which reads in sectors one by one and then transfers them over a serial line to the PC, you will get a DOS order disk image.

Apple floppy disks contained 35 tracks with 16 sectors per track, for a total of 560 sectors. Each of these sectors contained 256 bytes of information, for a total of 143,360 bytes per disk. Therefore, DOS order disk images are always at least 143,360 bytes long. Sometimes on the Internet you will see a disk image that is 143,488 or 143,616 bytes long; this is probably a DOS order image with extra header information before or after the image. In most cases, AppleWin can automatically detect this and handle it.

ProDOS Order Images:

ProDOS order disk images are very similar to DOS order images, except that they contain the sectors in the order that ProDOS numbers them. If you compress a disk with Shrinkit on an Apple, then transfer it over a modem and uncompress it on the PC, you will get a ProDOS order disk image.

Since ProDOS order disk images contain the same information as DOS order disk images, simply in a different order, they are also about 143,360 bytes long. When you use a disk image of this size, AppleWin attempts to automatically detect whether it is in DOS order or ProDOS order by examining the contents of the disk. If the disk was formatted with a standard operating system such as DOS or ProDOS, AppleWin will successfully detect the format. Otherwise, it will revert to DOS order, which is by far the most common format. To force ProDOS order, give the file an extension of ".PO".

Nibble Images :

Nibble images contain all of the data on a disk; not just the data in sectors but also the sector headers and synchronization areas, all stored in the same encoded format that would be recorded on a real disk's surface. At 232,960 bytes, nibble images are bigger than other images, but they can be useful for making images of copy protected software.

Hi Tobias! Yes that is right, however, the setting for moderator

I am willing to approve new members as they apply or to remove the
SPAMMER infiltrators as they sneak in and ply their ugly trade.
Either way is fine with me and I am quite happy to be able to at
least regulate the SPAMMER abusers in some fashion.

SPAMMERs are the lowest form of internet users, really they are

Also I note the word `Yet` used with regards to ImageTool `user

I think it would be very helpful in expanding what catweasel can read
and write if users can add to and experiment with the config.

It would mean we could test using our own disks that we come across
without the need to try and mail them back and forth.

I think it could also take a lot of the load off you as far as adding
more formats. Personally I'd really like to see this.

-- Here is further information for MicroBee support under Catweasel --

Stewart Kay. 24 November 2008

This document describes the physical layout of most of the common disk
formats used my the Microbee computer.

The Microbee uses a Western Digital WD2793 disk controller on later models
for formatting and accessing floppy disks.

Low level format
The low level format method employed on disks allows for reading/writing
sectors on normal PC floppy controllers.

There is a problem with the original formatted disks that causes a problem
to FDC controllers if not taken into account. The native format programs
used the value of 0 on both sides of the disk in the sector headers. This
issue is usually the 'show stopper' when trying to access Microbees
disks on
modern hardware.

The WD2793 controller ignored the Side value so was never a problem on the
Microbee hardware. The side issue is present on all native DS40 and DS80
disks. 3rd party formatting tools usually wrote the correct side
numbers for
both sides of the disk.

The side issue must be considered a possibility on ALL Microbee disks.

Sector numbers
Sector numbers are always numbered 1-10 on the reserved (system)
tracks and
this format is also normally used for the data tracks. The sectors are
written in sequential order, no skewing is done at the low level.

One of the formats (DS80) differs for the data area where sector numbers
21-30 are used. The reason for this was likely to have been a protection
measure to stop SS80 and DS80 disks becoming corrupted if the wrong
disk was
placed into the machine.

To make a disk image from a DS80 disk format requires that the reserved
track's sectors 1-10 and data sectors 21-30 to be taken into account.

Data skewing
Skewing of the data tracks for all disks is used and was normally done by
the operating system in use. The typical skewing used is one of the

SKEW1: 2, 5, 8, 1, 4, 7, 10, 3, 6, 9
SKEW2: 22, 25, 28, 21, 24, 27, 30, 23, 26, 29

-- Further discussion RE: Prefered image formats and naming --

The Microbee disks are just CP/M so there is nothing else in there to
identify itself. I know DOS disks and other systems can do this.

On the issue of image formats I wondered the same. We really need to
have plain raw images or CPC EMU compatible DSK or EDSK images. But
other types supported by LibDsk can be converted to raw or DSK using
LibDsk tools if we have too. I would have thought one would just tell
the Catweasel software what image format to output. DSK images are
very popular for the Amstrad and is a standard used by emulators.

For raw images I just created file extension of 'SS80' and DS80' etc.
and the uBee512 software then knows how to work with the images.
That's a separate issue though. They can create plain vanilla raw
images without any overheads can't they ?


| 298|298|2008-11-24 09:07:25|Ken|Possible Catweasel ImageTool enhancements?? User editable DiskFormat|
Hi guys, Here are a few idea's I have about enhancements to the
Catweasel ImigeTool software.

- Disk Formats config file (User editable).
- Pause Button.
- Clean Button.

Catweasel & ImageTool has to be the `be all` - `end all` of disk
recovery solutions on the face of the planet, but support for further
formats has been very slow in coming.

This I feel is mainly due to the full work load being on the shoulders
of one poor man.

Changing ImageTool to support a DiskFormats.conf (config file) would
allow a far larger section of the Catweasel community to expand the
formats available.

While recovering data, the disks used are often ravaged by time and
poor storage practices. Often cleaning of the drive mech is necessary
over and over again. Perhaps `Pause` & `Clean` buttons could be added
to ImageTool. This way part way through a read if necessary the
process could be paused and a disk cleaner inserted. The `Clean`
button could perhaps step the head back and forth a bit to help with

Thoughts? Idea's? Anyone?

Hi, My current motherboard doesn't support B: in the CMOS. (Gigabyte
GA M56S-S3)

Catweasel can of course access it OK using ImageTool.

But I am wondering how I can get around the issue under Win XP?

I am currently working with some formats that ImageTool doesn't
support yet (microbee) so I am using dsklib tools in dos.

No where near as good. I really need ImageTool's fantastic recovery
ability. But I will have to wait for that.

Is there a way or utility to bump XP into seeing the B: drive?

Or a way to use the catweasel controller so XP can see B: drive?

floppy drives very much especially the older formats like 5.25"

Hi, Thanks but running yet another PC here is not the solution I'm looking for. A solution that will work with the modern motherboard is what I am after.
I already have everything installed and running in my current desktop, I just need to get around this one issue.
I am also starting to think that for some reason the newer floppy drive controllers on the mother boards don't support a second drive? I note that in Linux there is no /dev/fd1 it would be interesting to confirm if this is so. If this is the case the only other way around it is to have a driver for Win XP that allows access through Catweasel.

I built a computer a couple of years ago, and when it wouldn't support
a second floppy, I downloaded the motherboard schematic to try to see
what was going on. It turns out this motherboard uses a Super-IO chip
that has a limited number of I/O pins. The motherboard vendor has a
choice of what to use some of them for. On mine, the two pins that can
be used as the drive select and motor-on for the second floppy are used
for something else -- I forget what right now, maybe fan control.

Hi Everyone!

Jens just confirmed that he put my Catweasel MKIV in the mail to me

After reading these posts I investigated my motherboard and I see that
mine only supports one floppy too. Its easy to check in the BIOS.

Can I assume that the Catweasel controller intercepts the floppy
cable's signals when writing to vintage floppies?

Wouldn't it only matter if the catweasel was idle and you wanted to
access that B: drive via windows or linux directly?

Shouldn't you still be able to use the catweasel drivers tools for
imaging floppies, and manipulating files on the B: drive since the
catweasel is in control, or does it still rely on some signaling from
the motherboard too?

Can somebody clarify this for me?

When using the Catweasel with it's supplied software such as ImageTool under Windoze, it will be able to use all connected drives. This is because Catweasel intercepts the drive cable. It is basically piggy in the middle.
The problems come in however when you want the original OS to use drive B: say for an emulator, or if the format you need to read is not yet supported by the catweasel software (ImageTool etc).
Many formats exist that catweasel currently can not read or write. Hopefully future releases of ImageTool will allow for a user editable formats config file which would help with this greatly.
A fix for accessing B: from the OS via Catweasel would be windows and linux drivers to allow the catweasel drive controller to become the floppy controller for the host OS.
Hope this is of some help in understanding.
Also congratulations on your getting a Catweasel MK4 Plus. You will love it. When the exchange rates return to reality I will be buying a second one myself.

Anything that gets the price down to something sane I'm all for.

I think AUD$100-$125 is a realistic price that one would be prepared
to pay. Add freigh and maybe up as far as AUD$150. Anything past that
and you really have a hard time affording or justifying a purchase.

Last I looked, the total cost to buy a catweasel and get it to
Australia ran out at close to AUD$230. :(

China or Taiwan manufacturing is more likely the cheapest answer.

Yes, it's a problem. But with a simple solution really for all us
Catweasel people.

Who do we have to beg, borrow, or bribe to get some drivers written?

Catweasel really needs more software developers on the job I think. :(

Such fantastic potential for so many years now. The hardware is great,
but the on going software development is just so slow unfortunately.

Could also a Max retry value be setable as an option from the menu etc?

That way when one is doing batches of disks you could set a max retry
value and walk away from the machine, come back later in the day and
not be worried that the drive has retried some 10000 times and worn a
track clean through the media. :)

Also I have another idea. Someone mentioned to me that it was only the
lack of a drive select line for B: ??

And that maybe a switch could be added to flip the two drives in and
out to get access to the B: drive?

Is this true? And if so is this something that catweasel could do for
us? Maybe in software?

I'm Yves, another CW MK4 enthusiastic owner, and a new member in this
group! :D

I've been doing lots of tests on Mac GCR disks with imagetool (Windows)
and cwtool (Linux).

Lately, I've been also imaging a lot of Apple IIc 5.25 floppy disks with
Imagetool (and saw that almost all of them are flippy disks -_-' ).
I had the same problem with AppleWin : although reading and imaging
looks ok (crc error sometimes, but second read pass seems to fix read
errors) I can't reliably run any single disk on this emu.
Same problem with 'cwtool', even when reading is 100% ok without any
retries. The resulting files are 143,360 bytes, as expected by
DOS/ProDOS image formats, but no still luck with AppleWin, which often
works ok with disk images available from virtualapple.org .

So here is the batch of painful questions ... :)
@Ken: did you manage to launch your 5.25" disk images with AppleWin or
any other emu?
@Tobias: Is there a coding order difference between Apple 2 5.25" disks
and Mac 800K DD disks?
@Tobias bonus question: Is Oric 3" and 5.25" support planned for next
release ? :)

@anyone in this group: Is there a way to contact Karsten Scheibler,
developper of the cwtool?

Hi Yves,
Unfortunately the few Apple IIe disks I had were too badly damaged. Many were shedding the media, some had grit in the covers, some bound when spun.
From memory I only managed to recover a couple that I could not get to read in the Apple emulator.
I have a DSE Cat computer here that I have never been able to test. If it works, once Catweasel supports Apple IIe Write ability I will try creating some disks that I will then copy on the real hardware and then try to read back in using Catweasel and run on the emulator.
Given that software dev for Catweasel tends to be slow, I have started looking into something called a Cyclone 20.
It is an open source project that uses an Arm development board and one simple floppy connector that you solder in.
Software development for it is going at a blinding speed even though it's only a couple of people currently working on it.
The device works on the USB port so you don't have to worry about PCI or floppy controllers disappearing on future motherboards.
If you Google the project you will find a thread on it in an Amiga forum and some YouTube video as well.
You might want to look into it also.
did you manage to launch your 5.25" disk images with AppleWin or
other emu?

The art with open source projects is clearly in providing fertile and well-tilled soil for others to plant their seeds.

I guess we'll see how it goes.
There will always be a market for a "proper" commercially supported product such as Catweasel I'm sure; I was amazed to discover that some people have difficulty soldering 12 pieces of wire. ;-)

What format does the microbee use for floppy disks? I have a reasonable
understanding of the cwtool configuration file format and can probably
whip something up which can at least READ (but probably not WRITE) the
Does it use an NEC765 or a compatible chip for floppy access, or does it
use a custom interface like the apple2 and c64 do?
Does it use MFM, FM, or some sort of GCR or other encoding for data?
How many sectors per track does it use? does it vary by track number?
How many bytes per sector? does this vary by track number or sector
number as well?
How many tracks per inch are the diskettes? 48 or 96?
Does it use one or both disk sides, or can it do either way?
If it uses both disk sides, are the sides interleaved (as on ibm pc
disks), or does one side come logically 'after' the other one (as on
some other disks)?

If you can answer some or all of these questions, I can probably make a
cwtool profile to read the disks.
Or, if you lend me a disk, I can probably figure it out by trial and
error from that.
(I'm also making a post on the microbee forums so I can access the files
and hopefully figure out the format from there)

Have a good day!

Hi All,

I have bought myself a shiny new Catweasel Mk4+ and I'm trying to use it under Linux, specifically OpenSUSE 10.3 which has kernel, with the hardsid-catweasel-0.06 driver which was made some time ago for the original Mk4 cards.

I have changed pci_module_init to pci_register_driver and SA_SHIRQ to IRQF_SHARED to make it build with the newer kernel, and installed it with modprobe - so far so good.

However, hsid_probe never gets called so the card is never initialised. Do you know if this driver should work with the newer Mk4+? Are the PCI vendor/device IDs likely to be incorrect?

Many thanks in advance for any advice!

| 337|336|2009-07-23 11:20:39|ollyatwork|Re: Catweasel Mk4 Plus under Linux?|
Hi all,

Just to keep you posted on progress... I got a reply from Jens Schoenfeld confirming that the PCI IDs for the Mk4+ are identical to the Mk4, so I gave up on the hardsid-catweasel driver and have moved on to the catweaselsid driver (http://freshmeat.net/projects/catweaselsid/) instead. After some hacking I've managed to make it build, install and detect the card and the SID that I have installed. Bonus!

However, I still haven't managed to get any sound out of it. GoatTracker just gives silence (although it does seem to be able to open the SID correctly), and the driver's own sid player gives lots of invalid opcode / cpu halted type messages and produces clicks and pops.

So, still no further forward really... I did have to hack out some init_input_dev calls to make it build, tonight I will try replacing them with input_allocate_device and see if that makes any difference but I'm not hopeful.

Anyone else got a working Catweasel / GoatTracker setup under a recent Linux kernel?

The reason why the probing doesn't work is that the subsystem may vary between 0x0002 and 0x0003. This is a Catweasel PCI Bridge bug, according to the Catweasel FD driver from Karsten at unusedino.de

Also: since VENDOR_ID AND PRODUCT_ID match an ISDN card from Tiger technologies, you must be perfectly sure your kernel does NOT load the Tiger driver in any way. You can see it in the dmesg.
You need to blacklist the corresponding module (man lsmod, cat /proc/devices, man modprobe and so on).

Hope This helps,

I'll be interested to see how you go with this.
I have my Catweasel MK4+ in a dual boot machine here and plan to re-install the latest Sabayon (Advanced Gentoo) Linux at some point in the future to try with it.
So far I have found Sabayon to be very good with most things. We are using it here on one of our servers and have added some really diverse peripherals with much ease.

I have read the cwhardware header file about 5 times and am still sitting
here scratching my head. There's a lot of low-level detail there
(thanks!), but what's lacking is the 10,000ft. view: What is the basic
methodology for reading and writing a track? I get that there's a way to
read flux transitions into controller memory and can see how you might
then transfer them to the host computer. What then? How does one "play"
FDC and pull actual sectors of data from the stream?

Writing is a complete mystery. There's some verbiage about timer values
interspersed with "pulses", but I see no explanation or even hint of the
overall flow. How is the track image constructed? What's the basic
theory of operation?

Finally, there's a brief mention of the need to "upload firmware", but
zero detail. Is this documented anywhere?

For the record: I'm no beginner in this field. I have a CS background
and many, many years of experience in hardware interfacing and firmware
development. However, there's just a little too much missing from the
header to give me a direction. I don't need detailed handholding, but
would very much appreciate a hand-waving explanation.

It's not my intent to be critical of the author, BTW. I can see
that a lot of work went into it. I'll even volunteer to re-word or
enhance it on the basis of any insights I'm able to accquire.

Thanks in advance for any help or insights!

again, thats out of the scope of the hardware documentation :) reading and
writing works pretty much the same - but all you can do is reading or writing
a stream of flux transitions.

this is the only thing missing in the header file ... you may look at the
linux driver for example. however, normally there is no need to upload the
firmware, because the driver will do that for you.

infact, little work went into it... only enough to make it work for me when
trying to understand the driver =P much of the header file is a direct
cut'n'paste of the original "inside catweasel" document from jens =) as said
above, it is explicitly ment to include all hardware info, and NOT any
further info on how to deal with highlevel data. however i am well aware that
it is not complete even in this regard, so if you have something to add or to
fix, just send it over and i will happily include it :)

anyway, here is some brief info:

first of all it would be good to know what type of software you want to
write - in particular wether that actually requires you to write a driver
(and if not, you dont have to deal with the info in the hardware header at
all). if yes, have a look at the various linux driver packages, they should
tell how you initialize the pci bridge, upload the firmware, and then work
with the hardware registers.

if all you want is writing user-mode software, then have a look at the other
header files (or the respective files of the linux drivers if you are using

the basic operation of reading/writing to disk is like this (simplified r/w of
a mfm disk):

first writing (this is actually easier than reading):

- read one "cooked" track from your disk image into a buffer
- encode the track to "cooked" mfm format, meaning adding proper sync bytes,
sector headers, checksums etc
- transform the result into a stream of raw mfm bits
- transform the result into actual timer values for the catweasel by mapping
mfm patterns to their respective timer values
- write the result to disk (for this there is a ioctl in the driver)

reading pretty much goes the reverse:

- read a track from disk (for this there is a ioctl in the driver)
- map timer values to raw mfm patterns (there are several methods to do this,
simple thresholds beeing the easiest)
- read through the stream of mfm bits, detect sync patterns, and extract
the "cooked" mfm bytes
- decode mfm bytes to normal "cooked" track data
- write out the data to your disk image

for examples on this process you can look at tim manns "cw2dmk" or
the "cwtool" and "cwfloppy" utils for linux.

before starting, i recommend getting familiar with fm/mfm encoding in general,
and with the datasheet of the floppy controller chip you want to "play"...
this will make understanding the above programs a lot easier :) also before
starting to write something in some specific obscure format, you should
probably try to write a regular pc disk first.

Ok, understood :-).

I'm familiar with how FDC chips do this in a general sense. So I follow
to this point.

This is where one plays games with inserting transitions to prevent an
excessive number of zeros, right?

Ok, the light just went on. The image consists of nothing more than a
sequence of timer values at this point, correct? And it's simply
understood that a transition is written when each timer expires? I see it
now, but it could _really_ use an explanation in just those terms
somewhere in the docs. Perhaps I'm just dense, but this point was
anything but obvious.

So, here again the result of the track read is a sequence of timer values?

Not following your wording. Could you give me a quick practical example?

Hopefully you can now see where I was (and in places still am) getting
twisted around trying to understand things!

I will try to write up a "Theory of Operation" for the Catweasel once I
get clear on the last few points. Would be very, very helpful to newbies
that want to beat on the hardware and/or do new things with it!

which you then map to 3 timer values (like 5,10,15)


when reading, you wont get exact values (like the 5,10,15 above), but the
values will vary. so you will have to quantize the timer values, for example
by matching them agains thresholdst (eg 7,12,17). another approach is to
implement sort of "pll" logic that will give you the proper bitpattern for a

I don't use my cw under Windows very frequently, but had reason to the
other day. I'm seeing some very odd behavior! Imagetool is getting the
diskette drives backwards. It believes that Unit 0 is my 5.25" drive and
that Unit 1 is the 3.5" drive. In fact, it is the opposite, with the 3.5"
drive being drive A and the 5.25" being drive B. What it believes is Unit
1 actually physically selects drive A and vice-versa.

Further, with the CW drivers loaded, I'm unable to use the conventional
Win XP drivers to access the diskettes. If I try to format a disk in,
e.g. drive A:, it generally returns an error indicating that it cannot
access the drive. About 2 in 5 times, it will succeed past this point,
only to fail about half-way through a format operation with a "not ready"
error. Under no circumstances am I able to read an MS-DOS diskette using
the Windows filesystem - it accesses the drive and hangs with no response
and the motor running. Only a reboot will clear things.

What can I do to eliminate this obvious contention between the CW drivers
and WinXP itself? FWIW, this does not happen under Linux with cwtool.
There, everything plays nicely and I can r/w diskettes using either


| 350|349|2009-10-18 23:18:08|Tim Mann|Re: Windows driver (mis)behavior|
It can see how the catweasel drivers and windows might not agree on the
drive numbering.

If the cable you are using to connect from the motherboard to the white
socket on the catweasel has plugs for two drives, with a twist between
them (that is, one plug on one end and two plugs near the other end
with a twist between the latter two), switch to using the other plug.
That will swap Windows's idea of the drive numbering but leave the
Catweasel's idea the same.

If your cable has only one plug at each end and has a twist between
them, find one that has no twist (or two twists) between the two
connectors you will use. Or vice versa, if your cable has no twists or
two twists between the connectors you are using, switch to one with one

I don't have a suggestion about the apparent contention for you, but
maybe someone else does. I actually never got the pass-through working
well enough with my catweasel to use it, but I put that down to having a
pre-production catweasel and/or problems with cable length and/or
termination on the drives I was using. For me it didn't work reliably
even with Linux booted and no catweasel driver loaded.

the drivers should switch between internal and catweasel drives automatically,

check if the first works for you... if not, then it must be either the cables

if booting works then you know the passthrough itself works, and further
problems are most likely related to the driver. however there have been no

Nice to see some more development. :)
And some really important things too.
+ User definable formats.
+ RAW mode for analysis of new formats.
- Broken Write for formats is a bit of a worry. (Hope there is not a long wait on this).
- Did the pause button get added to this release so one can clean the heads etc part way through a recovery?
- No MicroBee support?
However glad to see some progress.
If I can see a stable release with these new very worth while features I am planning on buying a second Catweasel MK4+ in the near future while the dollar is still strong.
Cyclone 20 seems to have stalled some time ago. So not currently viable. :(

Just installed the new driver and imagetools.
Seems to run a lot smother with the 5.25" drive.
Here is what I have found so far. (Some possible Bugs, some $ wish list / reminders, # some maybe I don't understand?) ;)
- Imagetool crashes on Detect with BBC micro & Unknown disks.
- Could not find MicroBee formats in the list of supported formats. $
- No 80 track support for BBC micro disks. $
- Could not read BBC micro disks.
- No Pause & Clean buttons during a read to allow for drive cleaning on stubborn recoveries. $
- Could not read past the first 2 tracks of a 360K IBM format disk.
(2, Track number in header doesn't match current Track)
Yet other times it will read 2/3 the way through fine before getting the same error.
- Could not write an Apple IIe disk.
- Could not write a C64 disk.
- Could not find the user defined profile feature for creating new disk formats. (In ImageTools) ? #
- Could not find RAW read feature. (In Image Tools). ? #

mmh this sounds strange, you might want to play with the drive timing tweak
values (you must edit the ini file directly atm for this) and increase some
of them a bit.

what kind of drive are you using for this? writing 40 track DD formats will
not work well (or even fail completely) on 80 track HD drives unfortunately.
on a 360k dd drive it should work though :)

look at the beta page, the imagetool can load user defined formats
from "fdparm" and "libdskrc". simply put them into the same directory as the
imagetool, and then run the imagetool. i have linked the files i am using for
testing on the beta page aswell, they contain pretty much every format i
could find in this particular fileformat (feel free to send more) :)

please be aware of that this is a very new and probably not very well working
feature, i havent tested it much at all (and many settings probably dont work
as intended yet).

this is not ready yet, i am preparing a commandline tool (cw_raw) for this,

Just tried to detect and read a MicroBee CIAB 3.5" SS DD 80T Disk.

On detect 9/10 through the scan you get a `Error Reading Disk' Try again / Abort.

When trying to read the disk after selecting the correct format you just get a complete page of Red fail blocks with a double stepping noise on each track. Second pass does the same thing but a bit faster.

As a simple side test selecting a MSdos format shows green blocks on the same disk.

So the new User(Libdskrc) option isn't working so far, but it does come up in the menu.

Also for your own tests as mentioned previously a Microbee disk can be created on a normal PC using the software located at


Just following the simple making_disks.txt directions.

Then you will have a disk locally there to test with.

On the first track I get a full red line (track) and.

Clicked continue and I get Green & yellow blocks.

Second pass it writes again the first track but this time mostly successful.

As it continues to pass over the bad tracks it eventually gets it right with some interesting and strange results on the way.

Eventually after many passes it has written the disk OK.

I then tried to verify the disk.

After about 4 passes it finally says all blocks are green.

First pass showed mainly green with some black, yellow and one red block.

Tried the same process again. This time with out erasing the disk first.

This time did not get the error writing disk on the first track.

However took 14 passes to finally get all the data written green.

Verifying this time took 12 passes.

I then tried to read the disk. This took only 4 passes. But the last 2 passes were very quick and only over one last block.

I've connected a Shugart SA-851 drive to my Catweasel using a DBit FDAFAP adapter. Imagetool 3.2 (under Windows 2K) doesn't detect the drive (the "Drive" dropdown is empty). When I use Tim Mann's cw2dmk tool under MS-DOS 6, the head loads and I can read tracks, but I get 5 retries on each track and about 4 bad sectors for each good one. So things are kind of working, but not really

I've hooked a 3.5" drive to the Catweasel, which is detected by (and gives me perfect reads) with both Imagetool and cw2dmk, so I believe the Catweasel is working. I've also tried more than one SA-851 (I have three SA-851s, in two different drive cabinets using two different 50-pin cables) and seen the exact same results. I suppose it's possible that all three drives, and/or both cables, are bad, but it seems unlikely to me.

Any suggestions would be appreciated.

    I have been able to setup recently an interesting vintage configuration (Amiga 1000 + Sidecar + TrackStar 128) that operates perfectly and I'm now trying to create Apple2 disks found on the net (.DSK images) using the Catweasel with absolutely no success.

    Until now, my Catweasel works perfectly with a P4 under XPSP3 using a 5 1/4 floppy disk to read/write 1541/1571 disks, even fliped ones.

    The catweasel had been able to read the protected (apple formated) tracks of the trackstar disk but I absolutely can't write any apple disk. Does anyone have an idea ? Is there a chance to write apple 2 disks using Catweasel ? What would be the tricks ?

    Frankly Catweasel has always been a nightmare.

    The hardware and principal is sound, however the software development has always been a dead end.

    Your best bet is to grab something called a Kryoflux.
    It is a USB device that does the same thing except it works and software development for it continues at a regular and productive rate.

    Catweasel really needs the software development side to become open source if it is to go anywhere. The original developers have just never had the time or man power to make it work properly unfortunately.

    Good luck with your archiving!.

      I have developed some programs in the past to read odd floppy formats by banging on the catweasel registers directly, no driver in between. Great.

      But now I want to read a large collection of disks from a Compucolor II computer from 1976 or so. This used an ingenious approach to their disk controller -- it was inexpensive, but at the price of low storage capacity.

      They took the serial port controller chip that was already in the machine for RS-232 and programmed it to operate at 76800 baud (9600 * 8) by using what was supposed to be a test-only mode of operation. Each byte takes ten bit times: a start bit, 8 data bits, one stop bit, at about 130 uS per byte. Sectors are identified by having a gap with no transitions of around 10 byte times (1.3 ms), then a sector of 128 bytes encoded as (0x55, track byte, sector byte, 16b crc) (0xFF, 0xFF, 0xFF dummy bytes) (0x5A, 128 data bytes, 16b crc). To make it work, the 8080 CPU had to have interrupts disabled, and of course no serial port operations could happen at the same time because the hardware was multiplexed to read/write the floppy.

      To the best of my understanding, the catweasel simply cannot decode this format because its 8b counter will saturate, even at the lowest sample rate.

      Can anyone think of a clever way to get it to work? If not, I guess I'll have to spend a couple months of free weekends breadboarding something to do the job, but I'd rather not.

      Hi codonodoc,

      have you checked the rotation of the drive? Some of thoose early low-cost-solutions rotate with only 50 rpm to sort the data right in time. Given that, everything should fit with a usual 14 MHz RAW-data dump if you read with 360 rpm (supposed it's 5.25"-drive).


      | 404|402|2013-04-10 19:04:04|codonodoc|Re: Any way to sample disk format with really slooooow bit transitio|
      The drive runs at 300 rpm, so there are 15360 bits to be read in 200 ms. If the gap between sectors is 1.3 ms, a 14 MHz sample rate requires a 15b counter.

      In fact, there can be an even larger gap between sector 9 and sector 0. Although the gap is nominally 10 character times, there is roughly 100 character time gap between the last and first sector. I'm not sure why things aren't more evenly spaced, but some of it was to account for variation in drive speed, but no enough to account for all of that extra time. Anyway, that gap is over 10 ms, and even a 16b counter might not be enough.

      What I really need is a way to reduce the sampling rate significantly. Not knowing the design, does it use a crystal oscillator, and could I replace it with a much lower one and still have things work?

      | 405|402|2013-04-10 21:05:24|Krause David|Re: Any way to sample disk format with really slooooow bit transitio|
      Hmmm I don't know if it is allowed to say that here, but the Kryoflux samples with 24MHz to 32Bit resolution, from what it reads at the forum! So everything should be in the streamfile, wich is well documented...


      | 406|402|2013-04-10 21:26:35|Krause David|Re: Any way to sample disk format with really slooooow bit transitio|
      There's an interesting Info about this problem and how the solved it with the Kryflux on http://www.softpres.org/wip:2009-10-13

      Acording to that the Kryoflux can sample at least 600ms without a flux-change bevor the timer overflows!

      like a path back to create media as the person interested has a lot of
      DEC hardware he wants to test and would probably need 8" floppies back.

      He is capable of creating his own imaging setup at this point, but I
      told him of Catweasel and Kryoflux Just not sure about costs and tradeoffs.

      Hope that is a good question for here as it is a bit off just a

      As said before very often, the main problem with the catweasel is the lack of developers support! With the kryoflux you get an active forum with more than 500 users and much support from the developers side. The software runs quite fine on win, mac and linux and you are able to read even (to some extend) copy protected disks! The write back feature is still in progress and not stagnating. The next big step will be user-scripts giving the opportunity to add more weird formats...

      ... so we have to face the facts!

      I am happy to be a backup moderator (or the primary if needed).  As I said before, I already moderate a few Yahoo groups, including approving people that want to join the group so as to keep spammers out, so it's a task I am able and willing to handle for a long time even if I lose interest in the purpose of the group (and in fact, I don't really do anything with my Catweasel board anymore - but that's my point - it's an important enough group that I will happily moderate it as long as needed). 

      But more importantly, whoever you give access to as a moderator, you should probably make sure that one person is selected to be the new primary moderator so that we don't clobber each other.  So I defer to your or the group's wisdom and desires on this.  My aim is to serve, not to control.

      I have a Catweasel MK4 and I've used it for reading Amiga disks. Now I
      noticed that the card's SID sounds are gone.

      I have two SID chips (6581 and 8580) installed and I've checked that
      both SIDs work and that the Catweasel's jumpers are set correctly.

      I can hear a very faint sound from the left stereo channel coming from
      the 1st SID chip and equally faint sound from the right stereo channel
      coming from the 2nd SID chip but that's all.

      I've also checked that the computer's sound card works: CD audio plays
      loud and clear through the same connector which I'm using for the
      Catweasel's SID sounds.

      What could be wrong?

      Hi Janne,

      the MK4 has a DC/DC-converter for the 12V-suply to separate the audio-part from the digital-part and avoid noise on the audio-line. Therefor GND from the catweasels audio-output has to be connected with the soundcards-GND via the cable. If it is not connected thru the cable you will have no sound from the catweasel even if the same cable runs fine with the inbuilt CD or DVD (because they already are connected to GND by themself)!

      So check if the GND of the catweasels audio output is connected to the computers chassis while the cable is in place...

      As far as I remember (I no longer own a Mark IV myself) there should be an 8pin chip nearby the audio-connector. It's the audio output driver (2 x opamps on single chip). There must be 12V DC attached to it with plus to pin 8 and minus to pin 4. If not, the DC/DC-converter is out of order!

      Hi tobias, thx for your reply.
      I installed Win2k and the ISA-CW (Address 320) and the Imagetool both from 2009 and afaik the actual ones.
      I configured my drives (1.44 MB 3,5 and 360KB 5,25). I changed the Image-Format to Apple2 and put a blank 5,25DD floppy in it. The "DSK" Image was written to the floppy (all green) but the Floppy does not work in the real machine. I did that with different DSK-Images but the result was the same.

      Now I will test to write a floppy with ADTpro via serial connection. 

      Because the serial connection is not so fast and flexible as the catweasel I would like to use the catweasel.

      Do you have any idea what went wrong with the catweasel ? Do you need the config, some screenshots ?

      the only thing i remember is that when i implemented the apple2 stuff, i used
      an actual apple2 disk for testing, ie to make sure reading works. then i wrote
      back the image to another disk and used the imagetool to read it back again to
      make sure writing is also ok. i dont have an actual apple2, so i couldnt test
      if the disks would actually work on it (and i never got any feedback about it
      back then either, so the only thing i could do is assume it works - or noone
      is using that feature)

      i'd make sure first that reading a disk produces a proper image for you - i
      don't actually recall what the exact format it saves to was either, perhaps
      its different from what you are trying to write?

      All I can say is that the copies works just fine one the Apple2e !!!

      So why do Diskimages from the Internet do not work if written with the Catweasel ?

      sector data, then it will not work.

      if you could point me to some documentation of that dsk format, then i can
      probably tell you what to do to write them using the imagetool :)

      Hi Tobias, if the informations are correct, the Apple2-DSK Images are exactly what the CA-ISA needs. No header just plain data. So way do copies from original disks word, bot no written back DSK-image?

      Can I do something that you are able to figure out, what the problem is?

      <catweasel@yahoogroups.com you are correct.... and sorry, i have no idea. do these dsk images have the
      same size as the images created by the imagetool?

      Hi Tonias, yes, they have the same Size.
      The Apple2-Dos33 is copy with the Imagetool3 of a working Apple2Disk. 
      I wrote it back to a blank floppy and it works.

      The other one is a DSK-Image from the Internet, that does not work if written back with the Imagetool and the CW.

        It is possible that the non-functional image has the wrong sector skew.
        Apple DOS 3.3 and ProDOS used different skew values. There's an informal

        suffix is "ProDOS order". However, I have seen many images that do not

        I haven't used Imagetool in quite a while, so I do not recall if there's
        an option for image type. If so, try the other setting. If not, there
        are utilities that can re-shuffle the sectors.

        Just an update to my statement: It will not work with the kryoflux as long as you use a standard drive!

        The drives AGC (automatic gain control built into the drive itself) doesn't allow such long times between flux changes. It will simply raise the gain between the flux changes. This brings up the noise floor to a level that will be detected as additional flux changes by the kryoflux.

        So the release-time of the AGC of modern DD or HD drives hast to be modified to read such diskettes!
