stern mpu 200 -not awarding games

[slither]

So I came across a 5101 chip in some of my parts bins, and decided (foolishly), to test it in my working Galaxy. The game booted and played fine, but now does not award free games at the set thresholds, I have reset them a few times, and played many games, but no games are awarded, also the knocker no longer fires even when special is achieved. I swapped the original 5101 back in, and same issue, not sure what has changed , any ideas? Thanks...

the knocker is working in test mode , btw...

go over your dip switches, you may have flipped one that does free game to award points instead.

nope, they are all correct, not sure what I did here, never touched any dips, all preset values are holding, strange ,lol.

Its now working again, noticed it was adding 10 credits as soon as you ran them out to 0, on its own. I changed the dips to max 25 credits, and it now works, gremlins I guess ... Thanks.
