These are the remaining systems from my classic computer collection that I
am making available for sale.
Many 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 it would be better if I didn't have 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/emulators on my site, many of these are 16-bit
DOS programs.
MITS ALTAIR 8800 (1975)
- North Star SSSD micro disk system with two SA-400 in a MITS drive case.
- Lear Seigler ADM-3A CRT terminal
Installed S100 cards:
- IMITS 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
The Altair is considered to be the first "personal computer". Ed Roberts
who created it is credit with coining the phrase "personal computer". This
was long before the "IBM PC" existed.
Works perfectly, Runs, can use front panel, Boots and runs NorthStar DOS
as well as my own DMF-80.
This was my first computer with a floppy drive, and I put a lot of time
into it "back in the day". I have many disks of various software for it.
You can "try it out" with my simulator
I have original January and February issues of popular Electronics which
featured the debut of the Altair. Also, see my
D.O.C. entry for
