Preserving a NOS Basis 108
I was lucky enough to recently acquire a new-in-box Basis 108, a German-made Apple II clone with a Z80 coprocessor for CP/M. It's a big, heavy beast with a metal case and high-quality keyboard. The original owner was a Kaypro dealer who bought it for evaluation purposes and never used it. My original intent was to get it working and use it, but once I saw it, I realized that it needs to be preserved as is.
The system is a base model with no disk drives and 64K RAM. I might also need to find a ROM to add drives. So, getting it working is a bigger task than I expected, and the system is really an historical artifact. I have scanned its documentation, which is quite detailed and includes schematics and code. Interestingly, it has two sets of docs. One is a preliminary version in an unmarked binder stamped with the system's serial number. The other is a final, larger version in a branded binder. I've scanned the latter and will send to anyone who wants a copy.
Would like to hear your thoughts on the system.
