Pretty cool as a design like this should be able to better preserve old system behavior than what DOSBox etc. can achieve. Although it seems a bit slow side at 50 MHz, I guess it's not a pipelined design? Not that original 80186 was pipelined either. :)
The 80186 won't be able to play many games that you remember... it wasn't really PC compatible.
This is pretty cool. A PC with an 80186 CPU is a little weird, though; I don't think many of those actually existed. It seems like virtually everybody went straight from 8086 to 80286
It had an 80186, 1MB of RAM (extreme at the time) and many other niceties that a normal IBM PC didn't have. I think it even had an external MMU, at least it could run SINIX. Though there were UNIX clones like PC/IX and early XENIX versions that ran without MMU on stock IBM XTs, without protection obviously, so I'm not certain what the story with SINIX on the PC-D was.

I cut my teeth on a "Siemens PC-D", a German variation on the IBM PC. Not quite compatible but almost.

I'm holding one in my hand right now; the HP200. There were others: https://en.m.wikipedia.org/wiki/Intel_80186#In_personal_comp...
From your link: The 80186 would have been a natural successor to the 8086 in personal computers. However, because its integrated hardware was incompatible with the hardware used in the original IBM PC, the 80286 was used as the successor instead in the IBM PC/AT. In other words, the few "PCs" which did use a 186 weren't fully PC-compatible.

The RM Nimbus was 186-based ( https://www.thenimbus.co.uk/range-of-nimbus-computers/PC-186 ) -- UK people might remember it as it was pretty popular in schools in the late 80s/early 90s. It wasn't fully PC compatible though.
Bloody horrible computers, those.

Was that the one that came with a remote control to turn it on and off?

Boys and girls, this is how you do a resume. :)

The 80186 was an 8086 integrated with some of the peripheral chips mainly used in embedded devices. You can still get some SBCs with 8018 compatible chips.
It is one of the saner Intel's attempts at x86-compatible embedded CPU with integrated peripherals.
