Space Invaders model racing
« on: June 26, 2015, 12:39:58 PM »
I have a SPace Invaders board, Model Racing version.
Actually I dunno which game was installed on but I burned new 2708 (yes, uses 2708) taken from MAME and I used my spare logic board.
The game worked fine for 20 minutes and then the scree became dark.
I have activity on rams and toms but nothing on the screen.

Do you know if MR version schematics are available somewhere?
Any idea about the problem?

thank you

Would it be the same as The Invaders?   Scroll down on Paul's site and you'll see why I'm making the association.

no no, completely different. THE INVADERS is a single board; MR version is a replica of the "L" shape but supports 2708, so uses 5 EPROMS
