Weird freaky number substitution from rebuilt MPU

I bought a used Playboy MPU that had seven blinks for my Supersonic.

I sent it off to my buddy in Sacramento who rejumpered it and burned new ROMS for it, got it back to seven blinks, shipped it back to me.

I carefully configured the DIP switches in the manual, and it plays great, but some weird effects!

1. The sound is like a classic Hammond D3 organ on acid. Steve Winwood would love it. I think its the most amazing sounds I have ever heard out of a pin.

2. There is some funky numeral substitution in the scores, a one is displayed as a zero, ball one is displayed as a zero, ball two is displayed as a zero (Ball Zero?,wtf) Ball three is displayed as a three, normal, Ball four is displayed as a four, normal. Ball five is displayed as a four, weird, eh?
after ball five the game ends normally. the score itself is still correctly tabulated by the mpu, its just the display thats weird, I call it substitution. When I go over 199,000 points, theres a two in the far left digit so I know its just a strange software issue, anyway I could always just put that ultimate mpu back in but lose that badass Hammond organ sound, hard to choose..
