Freeplay Ball Saved CAVEMAN Evolution

Single PROM Single ♫ PROM


The CAVEMAN pinball (model #PV810) that we own has been improved and has now new functions. The main modification, is the replacement of U2 and U3 PROM by a new single EEPROM, integrating the FREEPLAY.

The video board and the joystick that were down, made the object of a troubleshooting (read the article).

The original damaged backglass was replaced by a reproduction printed on glass (read the article).

We then developed a specific expansion board and installed a second modified backglass.


CAVEMAN Evolution

This project has gave birth to a new game PROM. In this one, the game's rules has been improved and the video game is now setable in French, English or German (read the article).

We also installed two additional driven lights in the pediment of display, to indicate the number of remaining Caveman. These lamps are placed behind a custom backglass, which includes two small stylized heads.

The ROM for CAVEMAN EVOLUTION is available for free.


Expansion board for lamps and personalized backglass

On the original CAVEMAN, all the lamp outputs are used. It is therefore unfortunately impossible to visualize the number of caveman remaining, as provided for in the new rules of CAVEMAN EVOLUTION.


We got around this problem by developing a small expansion board, can control two additional lamps. Carte d'extension lampes

The second backglass has been redone, in order to add the two caveman heads.
