Hi guys & gals,
Finally diagnosed that the problem with my Centipede is with the logic board. Where is the cheapest place to send it to get it repaired or replaced? So far the top one is Mike's Arcade at $60 + shipping...
For all the techies: RAM is all okay, ROM is okay, it's blowing out resistors. I replaced 25 of them, powered it on and still the same high pitched noise. Power going into the board is fine (metered and locations checked!). Power from the video connector on the green circuit is 3.2V when it should be 0.2...
What caused this? The "smart" ARII sent out +14V on the +5V line.
