I'm assuming that the 286/20 is a series II type with monitor built in? If so, it has a single density floppy controller built into the IOC board. You didn't post any pictures so I can't tell if there is a controller set there. Until I left Intel, all the disk controllers were a two board set. One board was had the 3000 series bit slice chips and the other board had the analog board. When I was there, the double density, M2FM boards sets were that way. The series II keyboard was just a regular parallel, 8 bit keyboard. The earlier MDS 800 chassis required a serial terminal. Most of these were made by BeeHive. I left there when they were basically shutting down the development systems. They wanted to move me to Rosedale, Ca.

Mostly Intel, 1 Matrox video card. Didn'y see a floppy controller anywhere, but I'll have to look closer. I have an Intel 286/20 chassis (the 20 doesn't mean mhz). Got to get me a keyboard and I'll be all set, right? O how I wish. There's an MDS keyboard on ebay, kind of pricey. Have to wonder where I'd stick the plug. No ribald suggestions please. So apparently my future has taken a turn for the very grim. As I'll be writing device drivers from this point until my death. Yep. It's all rawhide and buffalo chips from here on out. Maybe sum yu westerners can give me a hand. Fred, Chuck, Sellam. You're all westerners and cowboys apparently. Just rustle up some docs and software for me.
