Morning all,
I was enjoying a game this morning and the pin reset.
No power change evident, system went through start up checks, pushed start button and the game started from zero.
Have played a few dozen games since then and the same reset occurs intermittently.
Ball is not consistently in any position, score varies.
Have successfully played 3 of the 12 games end to end including full multiball.

I have owned the machine for about 9 months now and have done a bit of minor work listed below.
Coil no errors.
Switch no errors.
Any help would be greatly appreciated.
I have found no broken wires, solder connections, or fuses. (Open to rechecking anything/everything)

Name of game, manufacturer and year: 35th Anniversary Playboy, Data East, 1990

Did it ever work in your Possession?: yes

Did You Run the Diagnostics?: yes

Where did the game come from?: private seller

Have needed MODS been done?: Don't know

What was the last service you performed?: rebuild flippers, soldered broken wire to VUK(6 months ago)

Battery Corrosion: not evident, NVRam installed

Smell: no

Obvious Past Work Performed: knocker installed, sound board added, NVRam installed, all prior to purchase.

Check your 12 volts and see if it is consistent to the MPU. They might be causing your resets

5 volts

If you are only getting 5 volts at 12, then you might have to rebuild your power supply. That’s why it’s resetting... not enough juice to power board consistently. Sometimes a recap might be all that’s needed.

The MPU uses 5 volts, not 12 volts. I know as I bench test them with an ATX power supply.

Sorry, I’m thinking arcade machines. Yes, 5 volts.... are you getting consistent 5 volts?

Thank you both, I will find a good tutorial on checking these settings.

Very easy, top left of Mpu is two loops. One is marked ground, other marked 5v.

Clip a meter to them and run it out to playfield glass and play a few games. In an ideal world will not drop below 4.9 volts.

Check the 12 pin connector on power board, top right of board. I have seen dirty connections here cause reboots. Often it is burned. To test. you can take a small pick and bend in female connection barrels to tighten up and see if problem goes away. If that is the issue Great Plains sells replacement parts and Big Daddy usually sells kits.
