Summary: Bank Switching in //c not 65C02...

The bank switching in the //e and //c is done by the computer not the 
processor.  The chip that is in the machine is irrelevant.  65C02's cause
problems on some //+ machines because of a timing problem.  The Rockwell
65C02's seem to work, as do the 65802's (most of the time).
