Congo Bongo High Score Save Kit

A simple to install high score save kit that permanently remembers the top 6 scores and initials for Congo Bongo. Plus also includes Free Play with full attract mode screeens. Add to that a quick powerup selftest and a flip screen setting allowing either monitor orientation.

Installs in minutes! No special wiring or soldering is required. Simply remove the Z80 chip from your Congo Bongo CPU board, insert this Z80 CPU chip into the daughter card (pictured right) and then plug the daughter card into the vacated Z80 socket on the CPU board.
