I found my first 8080 computer, an Intel single board 80/10A. I have no
documentation. Is there a name for the physical bus at the bottom of the board
so I can search for its description? The power connections I can trace OK.
There is a 86 pin edge connector at 0.156 inch spacing, and another 60 pin
edge connector at 0.1 inch spacing.

The jumper pins on the board are numbered only, there are 80. Some I have
figured out already.

Once I find all the power connections (on the 86 pin connector), assume +/-
5 volts and +/- 12 volts, I will try it and test the serial connection
(8251). 8 of the jumper pins look like to set the serial clock frequencies.
It looks like there is current loop as well as RS-232. Haven't found any
jumpers for this yet. There is a single 2716 eprom, don't know what is in
it- a monitor or some control program that may not use the serial port at
all. There are 2 8255 parallel ic's going to top connectors.
