The 386SX has a 16-bit bus, which means that to do things in 32 bits
requires two bus cycles.  You could therefore run OS/2 2.0, or any other
386-specific software, on a 386SX.  It will just be slower.


For the ultimate in slowness, consider this:  you can buy a pin-compatible
replacement for a 286 -- a small daughterboard with a 386SX and some glue
logic.  (It costs about $300.)  It will run at speeds up to 16 MHz, but of
course it will run slower if you want it to.  I have this mental image of
an original IBM AT, running at 6 MHz, with one of these 386SX conversions
installed, running OS/2 2.0 -- it boggles my mind to think about it.  :-)
