Actually, no. If you look at the photos, in the bottom right corner the pcb is silkscreened "S-100 PC-AT Version 02" or 01. That's the board I have. Its purpose was to add the functionality to support MSDOS with a cpu board, like the original PC-AT compatible motherboards. There's a more recent S-100 to ISA converter board, that's what you're thinking this is. ISA was the slot with the PC-ATs. Version 02 adds keyboard and mouse to your dos system as well, plus some other tweaks.
Neil Breedan has 15 of them, or I have my spares here.

I believe the PC-AT support board allows to connect PC-AT compatible boards to a S100 system. The one I am looking for contains a 8259 interrupt controller and all hardware features that are needed to make the system IBM PC compatible, as described here : http://www.s100computers.com/My%20System%20Pages/MSDOS%20Board/MSDOS%20Board.htm Philippe Le dimanche 22 mars 2015 22:34:46 UTC+1, Matt a écrit : I've got this vague feeling that this is the "PC-AT Support Board", which is why you might not be finding it on the list? Someone help me out here. I just dug through my stack, and that's the board I'm finding. If so, I've got two spare of v1 and one spare of v2. Not sure what the differences are. Check the documentation and see what you think, and contact me off list if you're interested.
