Didn't that "Superbrain" computer use a
couple of Z80 chips in there? IIRC,
one was the "main" CPU and the other one handled I/O tasks of some sort
(disk?). I had a guy come into my shop one time wanting a couple of those
fixed, but I could find *no* data on them at the time and therefore couldn't
do too much for him...
Yes, two Z80's. One is the main CPU, the other is the DISK/IO processor.
Are there docs out there for this beast? I'm just
wondering how they divided
things up between the two CPU chips, and how they interfaced things...
Operators manual, technical manual and schematics are on my site.
Regerds,
Dave
