I have some boards with gold fingers that match S100, but are obviously
not. For one, they're dated to 1973 and from Intel. Also, they're two
inches narrower and 1.5 inches taller than an S100 board. What are they?
Maybe from an Intellec MCS8i?
I have such a machine. I remember cutting down an S100 prototyping board
to make another I/O card for it. Of course the result didn't come to the
top of the card guides, but it was big enough for the logic I wanted to
fit on it.
