OK, so you think you want a faster machine.
Well before you pump more cash into your existing PC, consider the following:

I have been running MINIX on IBM PCs and ATs for several months now, and
have tried out a variety of hardware combinations.  An out of the box
PC or AT 339 have no problems.  I have added an INTEL in-board 386 card to
the AT, and all seems fine.  I added an AST HOT-SHOT (80286 @ 10 MHz) to
the PC, and all was fine.  (Note: the HOT-SHOT can be set to boot off of
the 8088 or the 80286;  I only tried MINIX off off the 8088...)  I have
finally tried an INTEL in-board 386 PC card on the PC (80386 @ 16MHz) and
can no longer boot MINIX.  I get fistfuls of floppy disk read errors, and 
an eventual lockup.
     I plan to try some of the published 80386 patches which throw timing
loops into floppy.c, and see if that solves it.  If anyone has already
gone down this road with a turbo clone, I would appreciate hearing about it.
Thanks in advance.
