Call Echo Lake Pinball and talk to Jim Francesangeli. He has a replacement MPU for them that works very well. I have one in my Foxy Lady cocktail pin as I did NOT want to rebuild the MPU.
You think Omega Race is eaten up? You ain't seen nothin' like what happens to a Game Plan MPU.
It was around $230 shipped. Very well worth it as it is plug and play. It fits right where the original MPU went and the only mod I had to do was cut one wire tie on the pinball game's harness to allow for an extra half inch to reach one connector.
