The original RAM on the Colecovision is notoriously finnicky and needs +5v, -5v, and +12v to operate correctly. These RAM chips are known to fail over time and may also not work properly because of a worn/dirty power switch. Replace that RAM with modern RAM that only needs +5v to work properly!
The price INCLUDES all needed parts for this mod.
