I've got the manual for this one -- I've got
one myself. I'll get it
scanned and uploaded.
Thanks,
Jonathan

The two connectors at the top remind me of the MITS 2SIO board.
Chip on the left with the label seems odd ? looks like an EPROM. Not sure
why they?d use a UART (40-pin chip) and an ACIA, but it?s an interesting
two-port combo board.

I'm thinking one serial and one cassette. The 8251 for the cassette.
I can't make out all the chips at the pins? The board was hand laid out.
Is there nothing on the bottom but traces?

Subject: Can anyone identify this S100 serial board?
Trying to identify the S100 serial board in my Imsai 8080.

I assume it was a kit. There are wires from behind one of the ICs that go
to DB25 on the rear, along with other DB25s with a few pins (maybe
cassette input.)
Any help appreciated.
