IIRC the 80186 had and onboard PIC and integrated clock as well, but this was not a good thing for use in a general device.
I looked for info on this system and I could not find it. It was as close as possible to a PC, without being a PC. I strongly suspect it was a prototype and not a production model. My employer did a lot of business with IBM and the government, and a lot of "edge" equipment was scattered around. Could it have been a Xenix machine?
