Hi, I'm not sure what kind of system this extender card:
http://ana-3.lcs.mit.edu/~jnc/tech/jpg/tmp/SmallExtender.jpg
is for, but if anyone has a use for it, FTGH. It has 2x43=86
contacts.

reminds me of S100 bus or some alternaive bus at that time,
but memory is foggy.

43 is a rather unusual pin count. Multibus I used one 43x2
connector for the bus and one smaller connector with a
different (finer) pin pitch to connect to peripherals. But,
that extender would not fit a Multibus I card cage, the
blank area of the board sticks out too far.

I have a CPU board with similar format that I bought thinking I'd
eventually figure it out. Same boat, though, I haven't run across the
system it goes with. It does look very similar to many S-100 designs,
though.

I suppose there's a chance that it's for a piece of test equipment or
something more analog in nature, and not computer at all - all sorts of
equipment in the '60s had a card/backplane approach, and presumably field
engineers would have used riser boards along the lines of this one to
service them.
