You probably weren't directing that hint at me, since I didn't imply that
Microchannel was the first with dedicated expansion bus CPU's, (I was
thinking of Q-Bus, VME bus, etc.) but...

I didn't realize why IBM name the bus as it did until you mentioned it.
Makes perfect sense now, but now it also sounds a bit pretentions.  But then
it came from IBM.  I would really like to see a PS/2 running CMS (or would
that be MicroCMS?)
