So I brought home a Pole Position the other day. Tested and worked beautifully. However, it did not enjoy the 15 minute drive home. When I got it in, I first got a RAM error. I reseated the chips and that fixed that, however, now there is no driver sound. All the other sounds (except maybe the explosion) are there, but no driving car sound - which kind of takes away the fun!!
I have done some research into this and have concluded that there are 4 possible outcomes. The manual says to check Eproms at 12E and 12F, and another source I found said to check ( https://forums.arcade-museum.com/showthread.php?t=193521 ) the 7497 at 11C and 12B.
My problem is - is I have no idea where to find these parts! And do you have to order them specially for this game, or do they all act the same and I just buy one and replace it?
Thanks!
