First to be sold is my classic computer collection. Had hoped to turn it into a museum oneday but thats not going to happen. Much of the lesser systems in my collection have already gone, however these are what remains. This material is located near Ottawa Ontario Canada and is old/rare/fragile enough that I would prefer not to ship it. Most systems have not been run in some time, but were working when last tried. Some have full documentation and some are "just the system". Most of these can be seen on my "Daves Old Computers" website. Some have simulators/emutators on my site, these are 16-bit DOS programs and work well under DOSBOX which can be downloaded from http://www.classiccmp.org/dunfield/dos/index.htm ----------------------------------- MITS ALTAIR 8800 (1975) - North Star SSSD micro disk system with two SA-400 in a MITS drive case. - Lear Seigler ADM-3A terminal CRT terminal Installed S100 cards MITS 8080 CPU BD rev 0 North Star disk controller MDS-A2 CDC 64K Dynamic RAM MITS 88-SIO serial card Homebuilt dual 8251 serial card Runs, can use front panel, appears to try to boot (accesses drive) but I have not found North Star boot disks. Should be able to make them because I created a simulator at one time with images of all the disks. I also have quite a few 10-sector disks from other systens. Most likely you will need to toggle in a simple serial loader through the front panel and send and run NorthStar-DOS - it knows how to format and write a disk, so you should be able to create a boot disk. 191110: Found disks! - Works & boots North Star DOS or my own DMT-80 Have original January and February issues of Popular Electronics which featured the debut of the Altair. http://www.classiccmp.org/dunfield/altair/index.htm $10,000 This is an original Altair 8800 (1975), includes the Altair disk case with two SA-400 drives (1976) and a Leir Sigler ADM-3A terminal (1976). ----------------------------------- MITS ALTAIR 8800 (1975) Installed S100 cards: MITS 8080 CPU BD rev 0 MITS 4K RAM BD.
