"I'm in the process of writing new games (with some help from Anders) for
atari hardware."
you REALLY want to get some of Clay's 6502 'Get Well' kits. I haven't seen
the final design, but when I was up there working with him on it, we had the
idea for another board with a UART on it to slave together two game cabinets
(and be able to use it as a debugging board)
If nothing else, it gives you a board with more RAM and banked ROM space that
can plug into the game's 6502 socket.
Did you end up providing the wiring to support flash roms, Clay?
