Going through an old junk pile, I came across a couple of core boards:
Micro Memory, Inc.
PN 90360 8K*8 (MM-6800) Date code 7725
I have two boards (s/n 202 and 203) so likely purchased in pairs.
Anyone have any information on these? They have 86 pin connectors so
not S-100 though connector is about the same size.
For years, these have sit on a shelf on my 'round tuit' list of bringing
them up in one of my old S-100 boxes, so I've been cruising along
thinking these were 100 pin connectors. I got them out today so I could
find the manual (I have used the MMI s-100 8kx8 boards in an old company
project back in 1977 and those were about the same size and form.) The
core board is a daughter board on top of the board with the bus
connector and is likely the same module from the S-100 board. I'm
guessing the 86 pin bus is a Motorola Exorciser bus - so I can probable
figure it out from there, but I would like to find a manual.
I think my company had an Exorciser development system in the late 70s.
These were obtained from a dumpster dive. Pity I didn't get the rest of
the box, if so.
As usual, google wasn't extremely helpful with old pedestrian hardware
searches.
