PCB Game Cartridges and Game Chip Sets

PUTTING IT ALL TOGETHER

 

I will use the Tennis PCB Game Cartridge for this example.

 

 

On this game cartridge, you can see 3 chips “EPROM’s” with the copper colored stickers on them.

The white stickers identify the game and chip locations.  The “TE” identifies the game name “TENNIS”

The U1, U2, and U3 numbers identifies the EPROM chip locations on the board.

On this board, you can remove the U1 and U2 chips and replace them with the Game Chips Set that you have selected.

These are the two EPROM’s that hold the actual game program.

 

The Game Chip Set is a set of two EPROM’s that you can use to replace the U1 and U2 chips

on the TENNIS game cartridge so you can play different games using this game board.

This is why you can only have one game installed on a game cartridge at a time.

 

 

How To

Replace

Game Chips

 

When you just replace the game EPROM chips AND you are still using the original bios on your system

the Game List Menu on your PlayChoice 10 will display the name of the game cartridge that you have installed

and not the name of the game that is installed on the game board it self.

However, when you select, in this example, the TENNIS PCB from the game list on your PlayChoice 10 Display

It will actually load and play the DONKEY KONG game that is installed on Tennis PCB Game Cartridge.

The TENNIS Game Cartridge is now actually the DONKEY KONG game.

 

The only way that I know of to get the menu to display the name of the actual game that is installed

on the PCB game cartridge is to change the Bios “8T” chip on the Motherboard.

 

ORIGINAL BIOS

REPLACEMENT 8T BIOS

 

This Bios change will allow you to change the NAME ID chip, “U3 on the TENNIS game cartridge

I am using for this example, with one that has the name DONKEY KONG on it for the Play Choice Game Menu.

 

NAME ID CHIP

TENNIS PCB with DK CHIPS

 

This Bios “8T” chip will also make it possible to edit the play list manually.

It’s kind of a pain to do but if you don’t have a NAME ID chip for the game you can still change it this way.

 

Since the new 8T chip uses the coin switch to enter the edit mode,

This chip can only be used on a machine that is set to free play.
