I have an Imsai, a Z-100 and a Processor Technology SOL-20. Some special
notes:
Although it's not what I'm running, indeed they have been in a box and I
have not run them since 1983, I have the three Seattle Computer Products
cards required to implement 86-DOS (the OS that Microsoft bought from
Seattle Computer Products that became MS-DOS) on the IMSAI or any other
S-100 system. And I have 86-DOS itself, original floppy diskettes direct
from Seattle Computer Products. I bought it myself
back in 1980 direct from
SCP, it's original, and I think I have every version
from 0.33 to 2.0 (e.g.
MS-DOS 2.0).
Also, I have a working Helios disk system for the SOL-20, and I have copies
of PTDOS that actually run. This might just be the last working Helios
PTDOS system in existence, certainly there are not many of them still
running.
