 That wasn't completely serious ;) -- however thanks for the hint.  I 
wonder actually if any piece of software would let the code run in a 
"pass-through" mode and record what I/O accesses went past.  I reckon 
DOSEMU used to support that (and running the VGA BIOS) -- but that piece 
did indeed require vm86.  Then the sequence recorded could be replayed 
natively.

 Thanks for the food for thought! :)
