Used to see the 80186 on intelligent caching disk controllers
quite a bit. Though popular for smart peripheral controllers, it was
used on only a small number of systems as the main CPU. I've also
got a CPU upgrade card for the XT that uses the 80186. According to
Intel's own datasheet, it was an enhanced 8086-2 with a number of
onboard devices that previously required seperate chips and that it
offered roughly twice the performance of the 8086. The TRS-80 Model
2000 clocked it at 8mhz and was faster than even the early AT's.
