Definately not a PC (serial terminals only, different disk system, proprietary memory management unit etc.) Icon - ran Qnx. It think most of these were 186 based. I just scanned the technical manual if anyone wants it. Compupro 8086 S-100 system. NEX APC, a bit PC compatible, but I think the 8" drive make it qualify as a non-PC (and it ain't THAT compatible). DEC Rainbow - dual mode, the 8086 side would probably have been considered as a "PC compatible" before people figured out that just running a port of the same OS didn't make it so. I'm sure there are lots more ...
