Pole Position horizontal lines cars/signs

I know its a shot in the dark, but i'm hoping someone can help. I just picked up a broken Pole Position with a hacked up wiring harness. The boards were out of the game, and I don't know how to reconnect them. I'm hoping someone can help me get it wired up. I know the game is one of the most trouble-prone games ever, but also know the members of this board know quit a bit. Here are some pictures! If someone could please message me pics of your boards wired up, so I can try and match it up! Thanks!

Please HELP!!!!

Still need someone to open the back of their pole position and snap a few detailed pictures of the PCB wiring harness connections. I'm hoping to test my game, but don't want to hook it up backwards. Any help, Please!!!!!
 
the 2 large black connectors go to the PCBs. Looks like 1 of the connectors has been shortened. The orig connectors were different sizes, so if the complete connector is the correct size for one of the edge connectors, you know which it goes to.

the other collection goes to the control panel:
- red connector to steering wheel
- 2 wires to gear shift

My photo with the round stickers is the top connector, other is the bottom

Search for suggestions on how to start looking at these boards. Or PM Dick Millikan here and send the boards to him.

(and possibly do like I did and keep buying board sets until you get one that works!:eek:)
 
Guessing its not been on in a while?? At a minimum pull the board interconnect, take a look at the pins and perhaps clean them with some high percentage alcohol, and then reseat it. Make sure everything is lines up as there is a little slop side to side.
 
Took out the boards and attempted to clean and re-seat all the chips. A couple of legs started to break off a couple of the chips. Luckily I had another board set that I purchased on eBay that was reported as broken. This is the result! A semi functional game, with some missing sprites, mostly the cars and signs. I'm hesitant to start pulling the chips out as they may break. Any suggestions on where to start?

The manual does a good job of covering which artwork is on which custom chip. Since you have a spare board, you can possibly recover if one of the original chip pins breaks. I know I broke some pins when I set out to clean tarnish. My current working board has at least 1 pin that was fixed by soldering a trace wire to the pin stub.

I cleaned and reseated all the chips that mentioned signs and cars. No luck! It must be one of the chips soldered to the board, or potentially another chip is bad. Ive email Dick Millikan, but I don't know if he still works on these. I guess ill have to live with the horizontal lines through the cars and signs unless someone else has a suggestion? Thanks again for all the help!
