Item #: MPU004
Our board is plug-and-play compatible with the original board set (assuming the common 512k Game ROM). No special tools or mounting tricks are required and the swap can be done by even the most novice of installers.

This completely redesigned board replaces Data East's MPU/Driver Board part numbers:
  • # 520-5003-01
  • # 520-5003-02
  • # 520-5003-03
  • # 520-5003-04

Benefits over the original board:

  • Williams type mounting holes for ease of install
  • No batteries required for memory retention (no acid damage)
  • Simplified driver design using logic level FETs
  • Upgraded switch matrix drive for better durability (good to 100v back drive)
In addition:
  • Board is made with 100% through hole components
  • No custom parts used in this design (all parts can be purchased through usual suspects)
  • Major component designators carried over from original design so original schematics can be used
  • Jumpers and ROM configurations clearly labeled on silk screen
  • Board comes jumpered for the 512k Game ROM (80% of games)
  • Board comes with complete set of schematics

There is a jumper that must be moved based on the size of the game EPROM used. This jumper on our board, as well as the original D.E./Sega boards is clearly marked as jumpers J4 & J5. The default jumper setting for the 512k EPROM version (J5). The jumper would need to be moved to the J4 setting if the smaller 256k + 128k version game ROMs are used instead of a single 512k game ROM. Starting with version 3 of this board a DIP switch was added. DIP switch settings for Data East setup. Board Schematics

Questions and Answers/Trouble shooting:

Q: Connector CN3 does not match the same number of pins as the harness connector! What do I do?

A: Data East was going to offer a line printer option so game stats could be printed; however, the feature was never implemented in software. Just plug the connector in (it will only plug in one way) and the game will play fine.

Q: My game will not start and the "Blanking" LED does not light up...

A: You have two 256k game EPROMs, and the MPU comes configured for one 512k EPROM. You can either change the jumper from J5 to J4 or get a single 512k game EPROM.

Q: Some of the solenoids/flippers/bumpers do not work properly...

A: The DIP switches at DS1 are not set properly. This diagram shows the DIP settings for Data East.

Q: Connector CN3 on the MPU does not have enough pins...

A: The extra wires are for an optional printer, simply plug in the connector using the key pin for positioning.
