Hello All,
I've purchased a Moon Patrol that worked properly when I bought it. I trucked it standing up from the seller to my house and carted it in. Since then, it plays, but the player cannot be killed. The usual ways to die are by saucers that bomb the players vehicle, or you can fall into craters or drive into rocks. However, the buggy can take all the bombs and rocks that the game can dish out, and the buggy just continues driving over the craters like they're not even there.
I've checked all ribbon cables for proper seating and pushed on all the chips that look like they could have wiggled out of sockets. Most chips are soldered on the boards, so there aren't too many that could have wiggled out of sockets.
Any suggestions would be appreciated.
On a high note, I had a Frogger that was having issues and I successfully diagnosed that a power supply replacement was required and it's now working great. Yea!!
Thanks all,

This is symptomatic of inadequate power to the PCB. I'm betting your
Moon Patrol has the same/similar problem as your
Frogger. Meter the +5V rail. I bet it's low, like 4.5-4.7V. If so, adjust it up to 5.05V and see if the problem goes away. I wouldn't go higher than 5.1V or so. Also, examine the edge connector pins for signs of damage, like burn marks and/or previous repair like solder on the traces. You could have a bad connection that is not providing steady voltage to the board.

To be fair, eXidy's price guide isn't as out-of-date as this book, but it could use some updating. Actual sale prices aren't always easy to get, though, so I'm sympathetic.
