The memory would be nice for IIc users but I have doubts about the value 
of the 65816 part. There were a few RAM cards that would let you use a 
65816. Problem is that there were only two programs that would take 
advantage of it. Virtually all IIc, IIe programs were written with code 
for 65C02 only. If there's no code for the 65816 then it'll only run in 
65C02 emulation mode and confers no advantages. Now if you could design 
in an accellerator then that would be a big plus.
