If you saw this CPU card in a junk pile and
didn't know it was a UNIBUS
card you'd mistake it for some kind of 8085 controller board with 74181s
on it. Sort of sick, a PDP-11/44 slaved to a 8085.
Hmm... Well, DEC cards have a pretty distinctive form factor, so you'd
probably guess is was something out of a DEC machine.
But acutally, the 8085 is on a card called the MFM (Multi Function Module). That contains very little of the CPU. There
are 2 other cards
with the main CPU on it (that's where you'd find the 74S181s) + cache,
more bus interfacing, etc. The CPU is 5 boards I think + 1 for the
floating point + 2 for the CIS (which I don't have in my 11/44).
