    This would be of little use to an Apple IIgs owner, considering 
the SuperNintendo used the 65C816 in a PLCC package (the socket on
the GS motherboard only supports DIP). You could use it in a Zip GS
or TWGS, but since this 65C816 was clocked at 3.58 MHz, you would 
have to underclock very close to the speed of a stock IIgs. Hmmm,
they may even have been custom 65C816 CPU's come to think of it.
