Ah... good to have the reference.
Looking at the pics, the CPU is an Integrated
Solutions QBus 68000 CPU
board.
Thanks for IDing it. I've occasionally wanted to run across one of
those, mostly because I used to build 68000-based comms cards (which
could take a 68010, but we never did that except with our VAXBI card).
A COMBOARD isn't suitable for use as a CPU card (it wouldn't be able
to arbitrate interrupts or DMA, it's a peripheral), but it'd be fun to
team up a 68K CPU with a downline-loadable 68K DMA peripheral. It'd
be easy enough to port Minix to that (I already have the Minix sources
for the Amiga).
The COMBOARD wouldn't handle disks (without a bunch of work), but
_does_ provide two serial ports and a printer port. That plus some
kind of Qbus mass storage could be a fun little system.
So... if anyone runs across one of these Integrated Solutions CPU
cards (and doesn't already have plans for it), I'd love to hear about
it.
