Happy New Year Everybody,

On the Bally/Midway MCR CPU boards there are 5 custom chips which look like
they are MMI PAL devices.
I'm assuming they can easily be copied once they are identified.

0066-313BX-XXQX (MMC01) - H-T Generator - Custom
0066-314BX-XXQX (MMC02) - V-T Generator - Custom
0066-315BX-XXQX (MMC03) - Misc. V & H Circuits - Custom
0066-316BX-XXQX (MMC06) - Misc. TTL Circuits - Custom
0066-322BX-XXQX (MMC04) - NVR Controller - Custom

Does anyone know what kind of devices they are or what they can be replaced
with?

I put the schematic here
<http://games.rossiters.com/manuals/MCR/MCR-PALS.jpg> .

Thanks,

Matt
