DE cpu versions

[paddythegreek]

Is there any difference between version 02 and 03 de cpu boards.
Just put an 02 version in a machine that has an 03 board in it and all 6 special solenoids don't work.
Grounded each coil tab and they all fire.

Ok think i've sussed it. 03 boards are non reflexive whereas 02 boards are reflexive so basically it ain't gonna work. Bugger

Yes, according to Clays DE/Sega guide at CPU Rev3 (BTTF) the special coils were cpu controlled "non reflective"
