4 Baby Pac-Man Games
04/04/00

We are currently restoring 4 Baby Pac-Man games. They started out as 5 games, but one has a pretty bad cabinet. They have PCB problems and are generally filthy. There is not much cabinet work to be done, so we are limiting the pictures until one is done.

Note: We will have some parts available if anyone else is restoring a Baby PacMan. Email us at: appolo@mediaone.net

Cabinet Shots

Baby Pac-Man #5:

#5 is a definite parts game. The cabinet while clean was missing artwork and had some holes in the side. It was missing too many parts to consider even putting it back together. It has also been taken to the dump. Still available (offers being accepted):

• Playfield plastics

• Broken Vidiot (Bad ROM sockets, Missing Amplifier chip, missing socketed chips)

• Broken Light Driver PCB (all solenoids energized - blows 1A fuse under playfield)

• Control Panel with stick, 4 flipper buttons, and 2 start buttons

Already sold or traded:

• Wiring Harness with speakers

• Broken MPU

• Coin Door

Playfield Debugging

There are certain problems with the playfield that may happen that can cause problems. These problems are not detailed in the manual or in the Bally repair guide.

One problem I encountered was that the game would not complete initialization once another (untested) playfield was added to a fully working game. The following chart describes the conditions that may happen and what the causes are. These were determined by taking a completely working playfield and removing the connectors one at at time to see the symptoms.

Any and all help or recommendations accepted.
