That's an S-10 computer.  What's the wiring harness from?

If you want to switch computers you'll have to have the schematics for
both and compare them.  There is a tool for removing the pins from the
plastic shell.  There are 1227747 schematics on the ftp site, once I get
it unpacked, but no 1228062.  May have to visit the library or buy the
manual for that one.
