CPU Board Generations.

There are three different "official" generations of the DataEast pinball CPU systems. All boards use a 6808 (or 6802) CPU chip, and are essentially a copy of Williams' System 11 CPU board (without the on-board sound circuitry). These are known as Version 1, Version 2, and Version 3. There is actually one other slightly different version of Version 3, which I call version "3b".

• Version 1 (#520-5003-01): Only used for part of the production of DataEast's first game (Laser War). The RAM at location 5D is a 2K (24 pin) 6016 RAM.
• Version 2 (#520-5003-02): Used from Laser War (partial production) to Phantom of the Opera. The RAM at location 5D is an 8K (28 pin) 6064 RAM.
• Version 3 (#520-5003-03): Used from Back to the Future to Batman Forever. Uses "non-reflexive" circuitry (CPU control) for the kickers and pop bumpers. Version 3b (my term) is the same as Version 3, but 3 extra pins added at connector CN3 for a printer option (Last Action Hero to Batman Forever).

All DataEast/Sega CPU boards are downward compatible (so Version 3 could be used in a Version 1 or Version 2 game). However, it is not possible to use a CPU Version 2 board in a Version 3 game, since the reflexive circuitry used in Revision 3 does not exist in a Version 2 CPU board. Also, to modify a Revision 3 CPU board to work in Laser War (Revision 1), some modifications to the board must be performed. Check out DataEast service bulletin number 6 for this modification, by clicking here.
