I've just encountered a new (well, to me anyway)
revision of the SuperBoard II (OSI model 600):
revision D, copyright 1980
I'm only familiar with REV B and this puppy has
some significant differences. All of these guys
had schematics with them when sold. If you have
a C1P or SuperBoard II, could you check the revision
and see if you have matching schematics. I'll pay
for a copy of REV D or any revision other than B
for that matter.
Thanks,
Bill Sudbrink
