FWIW, I was in contact w/a dude in the Chicago area

Tandy 2000 that would make it 100% PC compatible. It
involved an extensive rewrite of IO.sys, which I had
thought would be a big no-no, but from what you're
saying, not really. I do believe he was hacking
Tandy's specific DOS though. Never finished it sadly.
Not possible, unless you mean by "100% compatible", compatible on a
BIOS level. That might well be possible, but it's small comfort,
given the number of old DOS programs that twiddle the hardware
directly.
I wonder if the 80186 in the 2K might also cause some programs to
mistakenly assume that it's running on a 286, as the 186 has a number
of the 286 instructions not present on an 8086.
