    I believe there was a heavily modified one used in Rat Race.

    Quoted from chucktee:

    Could it possibly from one of the early SS pinballs (System 1-2) Aztec or Grand Prix prototypes?

    if you look at the photos for prototype Aztec, those don't appear to be 6800/6820 based designs.

    Quoted from barakandl:

    The ones in the bottom right look original to the board and like TI chips from about 1975-1979 era.
    Is rat race any fun?

    It's fun to play a couple of games on at a show but similar games were commercial failures. I wouldn't want to pay for one or have it take up valuable space.

    It might be like Ice cold Beer, best as a competitive game.

    It appears the only thing different is the lamp matrix design. What is the part number on those 8 drive transistors in the lower right corner.

    Of course, there was some modification done over for the 6 special solenoid switch inputs ( upper left corner ) but that appears to have been an afterthought.
