MacMESS is a good em cuz it does "Sinclair QL" a virtually unknown system in USA.

It is cool cuz it does the LEGENDARY FLOP from APPLE CORP., "LISA" computer."
(Which, by the way, if you have one, APPLE will give you an $8000.00 rebate on cuz Steve Jobs
feels so bad. (Really!)

Its cool cuz when I find my computer so intuitively  ;)easy to use, I can remind myself of all those
obscure codes and CLI (command line interpreters) that I once had to know. WOOF!! :-/

MacMESS is cool cuz when it emulates a PC, it does it complete with all the usual PC bugs, reminding
me why I choose a MAC instead. ::)
