Hello, I am trying to revive a Pole Position for a friend. Both of the ARII boards are rebuilt and working well. However, I am having a tough time getting any technical information on the NAMCO board set. It seems that most of the schematics are for the Atari version.
There are a few things I am trying to find/determine and I hope someone on here can help:
- Cross or source for one of the 0326 chips. One of the pins rotted off on a chip on the board
- Some of the electrolytic caps and battery leaked. I replaced and fixed the electrolytics but need to get some hi-res images of the PCB front and back to verify I can fix the traces properly in that area. Also need to verify the values for the resistors and diode in that area.
- The tantalum caps for the audio section are questionable and I would like to replace them all. Need to confirm the value and original working voltage on those to get the correct replacements. (I really dislike those tantalum caps from the 80's that tend to fail shorted)
I don't normally work on arcade games but do a lot on similar electronic from the 80's so have all the tools I should need to fix it.
My friend and his daughter really enjoyed this game and I want to revive it for them.
