Well, you can always do a simple hack to the pc532. Pin 1 of the EPROM is
currently tied to VCC, via a trace on the back of the board (it actually
goes from pin 1 of the EPROM to the VCC pin of the bypass cap right above
the EPROM). This was done on purpose in case we ever had to go for a bigger
EPROM (I could have made pin 1 connect internally to the power plane...). Cut
the trace and run a wire from pin 1 to A15 (e.g. on the back of the cpu),
then you can use a 27x512 (64KBytes).
