Quoted from Antennaejim:Any other ideas as to why high score initials are wacky upon saving? Mpu or Vidiot related?
Not Vidiot related, it has no memory ram. I would swap another NVRAM or 5101 just for kicks. Maybe then go into bookkeeping and clear the high score initial entries.
One last thing, are the initials set with the joystick at all? if so, the PIA on the vidiot controls that. They can pass the vidiot self test and still cause problems(if its an AMI brand chip replace it for sure?) either way swap the PIA.

Quoted from Crt1989:Recently acquired a Baby Pacman. Every thing works except sound. No start up sound, gameplay sound, etc. My test sound does work however, and I can adjust the loudness of the test sound with both my video pots. I have noticed that when both pots are all the way up I am getting a hum from the speakers. Anyone know what the problem could be?
Vidiot board has an issue.

Quoted from ForceFlow:U27 is a CPU, not an EPROM.
The sound EPROMs are U29 & U30.
EPROMs have a window in the chip covered by a label. This is so they can be erased with UV light and rewritten.
Be very careful about replacing a chip socket. The traces and solder pads are *very* fragile. If you are not an experienced in soldering/desoldering, or if all you have is a soldering iron (and not a desoldering iron), I would highly recommend that you leave it alone or send it out for professional repair. Once a pad or trace is lifted, it's difficult to reliably repair.
IMHO, vidiot boards are one of the worst boards to do work on since the traces and pads are so fragile. On top of that, there are no replacement vidiot boards available.
The primary reason why you don't see too many baby pacman games is because of vidiot board failures, and it was a tricky board to repair, so many games ended up getting tossed.
All true. I have repaired many and still do but it ain’t cheap.

Quoted from Isochronic_Frost:You should make a Pinside business or a thread about it!!! A lot of guys could use Vidiot repair service!
Also do you do the Vidiot Deluxe that was in GatG? I have a Vidiot deluxe and I can’t test it but I’d like to have a working on for when a Granny shows up near me!
I have fixed a few in the past, but I don’t have a granny anymore to test one in.

Quoted from TheCnyPinGuy:Okay after clearer thinking
My Vidiot only gets 9 out of 10 flashes
So at least it’s a start to fixing it
check the vrams. Only one might have failed.

Quoted from mohega8:Help! My sound gets mixed up after 5-10minutes of play on my Baby Pac-Man

//]]>I've acquired a clean cab in fantastic condition. New MPU boards and I've gone ahead and replaced all the headers. Upon start up it will skip the tune, however, everything passes in the communication test and I get the "ray gun" sound. The game plays perfectly, until about 2-3 games in after the first power-on, the sounds suddenly get mixed up. For example, the sound of the pellets being collected is instead the game start tune. I'm looking for ANY advice that can help narrow down this issue. Does this seem like a trace problem on the vidiot board? Possible capacitor issues? Wrong wiring? What could be most probable and where to look? I've worked my way from the power supply but must be missing something. Thanks for any assistance!
Bad PIA I think. Replace U7.

It most likely U10 or it’s socket. Any corrosion on the board? U10 often gets hit when the mpu battery leaks. Inspect the socket closely. It probably has some corrosion on some of the pins.
Quoted from RaoulJuke:I think you are right - when i applied pressure to the U10 and got another person in front of the game i was able to get it working and playing without issue until i unapplied the pressure and it instantly went off
Replace the socket
