I learned Microsoft Xenix on a Tandy 6000HD in

At one point, I had the Z80 I/O routines listing for the 16B Xenix,
courtesy of Microsoft. I didn't hang onto it. We were doing a Xenix
port to a 186/286 board where the 186 did all of the I/O. I was
given the TRS-80 listing as an implementation guide.
But a 68K is a whole lot more CPU than an 8086. One might even argue
that it's more CPU than a 286.
