I've got a couple of old IMSAI parallel interface cards, one with two
8255's on it and one with 8 8212's and a bunch of LED's. WOuld anyone have
information about these babies? I've had them on the shelf for about
fifteen years, thinking I might actually use them for something but have
never bothered. I believe I even once had the schematic of the 8255 board,
which has two 50-pin edge connectors with the I/O signals and a 26-pin
between them which apparently bears some of the control signals from the
bus. Unfortunately, I've lost track of the doc's.

Anyone have information, e.g. schematics switch settings?
