This is my third request, but I couldn't say with any certainty that the
first two ever went out. I have recently acquired several board sets
for California Computer Systems machines, and I would like to see what I
can do with them. I also have 4 Fulcrum SIO-2 boards, also sans
documentation. Does anyone out there have anything on any of these
boards? Anything at all, even to minimal configuration pointers or
default port addresses would be tremendously appreciated. I can write
BIOS code for them, but it's easier if I know where to send stuff.
The boot code for the CCS boards appears to be resident on the floppy
controllers, although I haven't attempted to read these chips. Also,
the 64K dynamic RAM boards are bank switchable, but there is no
indication on the boards as to how to use the bank switching facilities.
The SIO-2's should be fairly simple, and I expect they will help me
upgrade my Poly-88 (which runs unmodified CP/M) to talk to other
machines. That would be nice.
Anyhoo, if you see this and have any ideas, please drop me a line. I
reply to ALL mail, at least once. Thanks.
Marc
