Part number 5764-12091-00 aka MPU011A. D10881, D11392 or 16-8947 in manuals. Hard to find in good working condition, can be used in any System 11 game, however this board is needed for High Speed, Grand Lizard or Road Kings pinball machines or Alley Cats Shuffle Alley games as it has the components installed that are missing in later boards. Can also be used in System 9 games if you follow the instruction on www.pinwiki.com to merge ROMS and change jumpers, however this is not supported by Big Daddy and will void your warranty. Used board, tested and repaired and bench tested on a Williams test rig for 2+ hours by Eugene Marsh at www.irepairatari.com using the Two-bit Score test ROM. Board is extremely clean with new battery holder installed, you will need to transfer over or purchase the 2 game and 2 music ROMs. I highly recommend using Lithium AA batteries, a remote battery pack or having NVRAM installed (none included), currently *not* socketted for NVRAM. I also highly recommend a new power supply or rebuilding your original with our P/S rebuild kit. Pictures shows actual board being sold. 90 day warranty. Credit may be given for returned boards up to $150 depending on condition.

This is an original System 11 board from a High Speed game #541 with the 7 segment LED, but a later version with a jumper near the relay to fix a sound compatibility when used in later games, and with the zener diodes added to the back to protect the special solenoid switch inputs. This board also has had the Lamp Matrix section replaced and updated to MOSFETs to eliminate a lot of created heat.
