Hi
I have one that I fixed the front panel, a number of bad RAMs,
and added an extra RAM card to bring it to 64K. I then read the
ROM's in the disK controller ( state machine, not uP ) and
figured out how to format, read and write disk. I then wrote
my own BIOS and combined it with the CP/M I got from the net.
Ya, there are a few IMSAI fans here. I'll have to admit, I'm
not overly excited about the IMSAI series two but I do wish
them the best of luck.
