    Working on a 520-5000-00 PPB. This board was used on:

    ABC Monday Night Football
    Back to the Future
    Laser War
    Phantom of the Opera
    Playboy 35th Anniversary
    Robocop
    Secret Service
    The Simpsons
    Time Machine
    Torpedo Alley

    At CN9 (Bottom right corner, below the relay) there are 4 wires that come out of this board (and are missing from mine). From the photos I've been able to find online, I know that #s 1 & 3 are white wires, and #2 and 4 are yellow. What I don't know about is the order of the wires on the other end of the connector...

    So, if you can help me out, I need to know which order the wires are in-- we'll use the "pointy" end of the connector as reference.

    Thanks in advance!

    Page 31 in the Time Machine manual shows where the wires at CN9 are coming from. Looks like they are inputs for the 6.3v AC coming right off the transformer as shown on page 28.

    Quoted from YeOldPinPlayer:

    That's helpful-- thanks! It looks like it may not matter which is the "pointy" end of the connector-- since it's all 6.3v-- or does it? Are they all doing GI, or is some of it for inserts? Hmm...
