It consisted of a module which connected via a ribbon cable to the socket originally occupied by the Z-80 microprocessor. The module contained its own Z-80 microprocessor as well as additional components. It was potted with epoxy to prevent easy reverse-engineering. Additionally, the kit also replaced the four ''Pac-Man'' program ROMs on the main game board with a new code. Two other roms containing updated data for drawing character and maze were also exchanged. Finally, two relatively tiny supplementary ROMs containing new color data completed the modification.
