Memory Support
v02 was designed to support the SST39SF0x0A series of 32 DIP flash chips. However, the AT27CxxxR series of 28 DIP EPROMs have a very similar pinout and should work on the board by mapping pin 1 of the EPROM to pin 3 of the 32 DIP footprint. Other 28 DIP memory chips may work as well, but their pinouts should be compared to that of the SST39SF0x0A to be certain.
