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? Dick
