Speaking of multiple processors...

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... 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... -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of space, ?a critter that can be killed but can't be tamed. ?--Robert A.
