Well, I finally decided to see if my old IMSAI was still working.
I purchased it in late 1976 and used it through 1986.
Lots of modifications. When I left off, it was running a Z80 @ 6MHz
with the following S-100 boards:
CompuPro CPU board
2 CompuPro 64K memory boards with my own bank switching.
CompuPro Disk 1 8" floppy controller.
TEI Systems 5-1/4 floppy controller.
ADES hard disk controller with 33MB Priam (14") disk
3 Multi-I/O boards with a home-made 2716/32 EPROM burner, and clock.
Cromemco Digital/Analog board.
Muller Relay board.
A customized version of CP/M-80 2.2.
So far, I can boot to 8" floppy, but cannot use my hard drive.
I'll fix it, but it will take some time.
I seem to forget how it all worked so well 19 years ago.
Have a nice day....
