Galaga '88 (GaPlus) Color PROM binaries

[Guest]

Archived from groups: rec.games.video.arcade.collecting (More info?)

Hello - I'm repairing a Galaga '88 and one of the color proms may be bad.
I'm not having much luck locating the binaries for the four small bipolar
proms on the board.

Any help is appreciated.

Thank You and Best Regards,

Bill

Hey Bill,

Galaga'88 or Gaplus ? They're two different game boards. Galaga'88 is a two
board setup and JAMMA, gaplus is single layer and non-JAMMA. Galaga'88 also
uses RAMs for it's color pallette, so I assume you're working on a Gaplus.

Last time I looked http://www.romnation.net has the Gaplus images which
included dumps of the color PROM.

You are absolutely right. It is Gaplus - first time I've worked on one.

Thanks for the clarification. I'll give your link a go.

Best Regards,

Bill
