1981 Ms. Pac-Man restoration

Finalheaven:
That did it! :laugh2: She moves perfectly now. Interestingly enough, the game is playing perfectly while the C20 capacitor is still disconnected.

Regardless, I would like to replace the capacitor. Which capacitor should I buy exactly from radio shack?

Also, I'm noticing *slightly* too much read on the first two stages which gives the maze walls a sort of pseudo-3D effect by bleeding on the top and right side of each wall segment. I assume this is not intended and I should reduce the color via the monitor controls.

SirPeale:
They may or may not have them @ RS.  YMMV.

I was talking about resistor packs.  They look like a one-sided centipede.   But as you seem to have found your issue I guess they're fine!

Finalheaven:
It's running pretty well now. I notice some movements get missed and I'm wondering if this is due to the disconnected capacitor. What type of capacitor should I get? Like what rating?

SirPeale:
It's some kind of ceramic cap, and I'm not sure of the rating.  Someone in the other thread mentioned .1 uf, but if that's actually the value I can't say.

Finalheaven:
All done. Everything's in working order. Coin door lights completed. That was a lot worse than I expected it to be. Anyway. My last project will be to perhaps wire a difficulty switch for the difficulty jumper located on the board and add a sound switch somewhere.

Thanks for all the help. That was awesome/nuts.
