Oh Goodie!  Now we not only have the opportunity of waiting 20 minutes
for an '86 compilation/assembly/link, NOW we can wait that long for 68K
stuff as well.  What fun.  Emulating an 8086 on a 68020 can be done at a
substantial fraction of the 8086 operating speed (maybe faster).
Emulating a 68K on the intel thing though will be **SLOW** i.e. large
fraction of a second per instruction.  Remember the incompatible byte
ordering, the '86 poor performance overall, but especially with 32 bit
quantities, etc.  In a business environment, the cost of your time to
make this thing work (or the cost of the time to use it) would more than
justify the purchase of some 68K-based machine instead.

Perhaps this is a school related project?  If so, I would be less
inclined to disuade you from it, as it can't help but be a valuable
learning experience.  Have fun.
