A PS/2 Model 60 (or model 50 or 55 -- low-to-middle of the range) sounds 
about right, from what I remember of that range.  And FoxPro and many 
other things were fine.  Around that time, the common benchmarks for 
what you might call "real IBM (PC) compatibility" were "does it run 
Borland Sidekick", "does it run FoxPro", "does it run the Microsoft 
Flight Simulator" -- all things that some "compatibles"had one trouble 
or anothr with.  I recall Acorn making a bit of thing about that at a 
BETT show (1988?), because the PC Emulator did all those things, while 
RML's then-current 80186 "PC" offering didn't.
