Looking at the latest Jameco catalog I noticed that they started
carrying the *new* 65C816 and 65C02 CPUs rated at 16 MHz! This is more
MIPS than a 20 MHz Z80 that could be used in my Applicard clone.
It would be relatively easy to make a card for A2e with this fast CPU
and 128K (if not 512K) of SRAM. No bank switching needed if 65C816 is
used. Talk to the main CPU via a mailbox, like the Applicard.
The only question is: does anyone need such a card? Given the ready
supply of Apple 2 GS computers?
