• This is a kit to add to your ORIGINAL arcade pcb. 
  • This DOES NOT work on a Raspberry Pi, Arcade 1UP, a MAME computer, or any other thing except your ORIGINAL pcb. 
  • This is NOT a stand alone game board. This is an ENHANCEMENT kit. 

This is a daughter card that fits into the processor socket. This kit adds functions like free play, attract sounds and more!

A simple to install high score save kit that permanently remembers the top 6 scores and initials for Congo Bongo. Also includes Free Play with full attract mode screeens.


Add to that a quick powerup self test 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 and then plug the daughter card into the vacated Z80 socket on the CPU board. Thats it!

Easy Installation - Kit installs in just minutes. No board modifications or special wiring is required.

High Score Save -  The top 6 high scores and initials are remembered permanently, long after the game has been powered off. No batteries to replace ever.

Free Play - As an added feature free play support with full attract mode screens. Can be enabled or disabled via DIP switches. (note: original Congo Bongo did not have freeplay support). See Free Play sample screen shots.

Reset High Scores - The top 6 high scores and initials can be reset to the factory default by entering Congo Bongo test mode and following the on-screen instructions. See Congo Bongo Test Mode and DIP settings for specific details

Improved Test Mode - Makes it easy to verify DIP settings. Mini power on self test (POST) diagnoses the HS kit on every powerup.
