Super Zaxxon Replica Cart
Super Zaxxon is perfect for testing PLA replacements. Some of the bad PLA’s cause screen corruption when using Super Zaxxon. This is due to Super Zaxxon using a flip-flop to toggle access between the upper and lower half of its ROMs. This causes it to be very sensitive to any timing problems the PLA might have.
Always switch off the Commodore before installing/removing the cartridge. Failing to do this and you risk damaging the computer.
