               Apple IIGS Product Info
               Released  February 1996
 
       TransWarp GS 32K Cache Upgrade Available
 
     ============================================
 
This document may be distributed freely as long as it remains
unchanged. (c) 1996 ///SHH Systeme, Joachim Lange.
 
 
If you still have a TransWarp GS equipped with 8K cache, here is
the chance to upgrade to 32K. We have done a re-make of the
original 32K board and will offer these boards to the Apple II
community. Boards are immediately available.
 
 
Description:
 
Re-designed version of the original TransWarp 32K cache piggyback
board. Improvements in the new layout: careful and efficient VCC
(+5V) and Ground routing, _double_ decoupling capacitors for each
integrated circuit. Resistors and capacitors are SMT type
components. Shape of board and positioning of the main components
very similar to the original layout. Board has solder masks (solder
resist) on both sides. High-quality industry standard.
 
(A GIF picture of the bare board should be available at the same
location from where you received this document.)
 
 
Important note:
 
Speed upgrades on the TransWarp GS can be done by enlarging the
cache size and/or using a faster microprocessor and clock
frequency. It is possible to speed-up the TransWarp card to higher
clock frequencies, and our TWGS 32K cache board replacement also
works fine with these speed upgrades. However, due to the limited
speed capabilities of the TransWarp GS (design made in 1989),
nobody can _guarantee_ that _your_ TransWarp GS will work at the
non-standard speed (the clock frequency) you want to go. In other
words: Some TransWarp cards work fine at higher clock frequencies,
others don't, regardless of whether you have equipped the TWGS with
a 32K cache upgrade from us or from any other source.
 
 
We can offer you our TransWarp GS 32K cache boards in three
different versions: "do-it-yourself", "dirty-work-done", and
"almost plug-and-play".
 
 
==================================================================
   Option A:  Bare boards ("do-it-yourself")
==================================================================
 
--} Minimum order here is 6 (six) boards! {--
 
 
What you get:
--------------
 
Two-layer piggyback boards for the TransWarp GS with solder resist,
ready for soldering all components. A sheet of paper with short but
reliable instructions how to assemble the board. NOTHING ELSE.
Heavy soldering required!
 
--> With this option:
YOU ARE ON YOUR OWN. NO QUESTIONS PLEASE. NO SUPPORT. YOU ARE ON
YOUR OWN. NO QUESTIONS PLEASE. NO SUPPORT. YOU ARE ON YOUR OWN.
 
 
 
Additional parts required for full functionality:
--------------------------------------------------
 
3  (2-row x 10-pin) header connectors, gold plated preferred.
 
6  DIL-14 0.3 inch wide sockets (two for each 28-pin cache RAM)
 
1  DIL-28 super-flat 0.6 inch wide socket for the firmware EPROM
   (max. 0.1 inch total height from board surface!).
 
8  SMT (surface mount technology) decoupling capacitors 100nF.
 
3  SMT resistors 100 Ohm.
 
1  SMT resistor 10 KOhm.
 
3 cache RAMs 62256-xx or equivalent, xx for the speed desired
(-35ns, -25ns or -15ns, any value between these will suffice,
depending on the maximum clock frequency)
 
1  Firmware EPROM TransWarp GS (v1.7 or v1.8 required)
 
Very good soldering skills and the ability to insert the firmware
EPROM and the cache RAMs correctly!
 
 
 
==================================================================
   Option B:  Populated boards, without semiconductors
              ("dirty-work-done")
==================================================================
 
Since it is much cheaper to buy expensive semiconductors (such as
cache RAMs) in your own country, you might prefer this version.
 
 
What you get:
--------------
 
A two-layer piggyback board for the TransWarp GS with solder
resist. All non-semiconductor components (sockets, resistors,
capacitors, header connectors) mounted and ready for use. A sheet
of paper with short instructions how to add the components not
included with the board. All board functions verified. No soldering
required.
 
 
Additional parts required for full functionality:
--------------------------------------------------
 
3  cache RAMs 62256-xx or equivalent (0.3 inch wide), xx for the
speed desired (-35ns, -25ns or -15ns, any value between these will
suffice, depending on the maximum clock frequency)
 
1  Firmware EPROM TransWarp GS (v1.7 or v1.8 required)
 
Enough skills to insert the cache RAMs and the firmware EPROM into
their sockets correctly!
 
 
 
==================================================================
   Option C: Fully populated boards, without Firmware EPROM
             ("almost plug-and-play")
==================================================================
 
 
What you get:
--------------
 
A two-layer piggyback board for the TransWarp GS with solder
resist. All components but the firmware EPROM soldered and ready
for use. The board includes all sockets and three 32K cache RAMs
62256-15 or equivalent (fast enough for processor clock values of
14 MHz and more). A sheet of paper with short instructions how to
add the components not included with the board. All board functions
verified.
 
 
What you need for full functionality:
--------------------------------------
 
1  Firmware EPROM TransWarp GS (v1.7 or v1.8 required)
 
Enough skills to insert the firmware EPROM correctly!
 
 
 
Another important note
=======================
 
The TransWarp GS firmware version 1.5 that came with the TransWarp
8K version does not work with 32K cache boards. You absolutely need
v1.7 or v1.8 for 32K cache operation.  Since the firmware is
copyrighted material, we cannot supply copies of the firmware.
 
The cache RAMs required for the 32K cache have many different
denotations. It's almost impossible to list all kinds that are
available and suitable. If you want to order cache RAMs from
elsewhere, just be sure to order three 32K * _8bit_ wide static
C-MOS RAMs in 0.3 inch wide DIL (dual-in-line) package.
