Another option is if you have a TransWarp acellerator. This is the one
place 
where you can directly replace a 65C02 with a 65816. It apears that the card
senses the 65816 and reconfigures itself for that processor. I've
replaced 
the 65C02s in all my TransWarps with 65816s. Unfortunately there's only
a 
couple of applications that take advantage of the 65816 in a IIe and I'm
not 
interested in using either of them. Sigh!
