I recently picked this pin up and have started to dig into the problems
When I go into the audio test mode I can barely hear the audio coming from the speaker, as it cycles threw the sounds.
It looks like I have a bad audio IC.The audio IC is a 5 pin. It has a Motorola part number that I cannot seem to find a repalcement for. The machine dosenot have the audio extension board installed.(I am looking for one) I have checked the settings and the jumpers.It has the White Labeled Audio ROM.
The game powers up, I can go threw the test mode all of the lights and solinoids work. The displays work. I am able to start up a game, play it for a few balls and then it will stop and flash game over. restart a game and go threw all three balls.
The original owner indicated that he had sent the Driver board in to a place in Texas and they did an exchange.
On the main proccessor board the two 6810 40 pin chips were socketed and repalced by someone else(I reflowed the solder on the sockets. There is a 6808 in one socket and a 6820 in the other. I see the manual calls for 6810's. Were is a good place to pickup a pair?
When I depress the main board Diagnostis switch with the coin door open the lower Led stays on.
Someone has upgraded the caps on the Power Board and the Audio board. I have reflowed the solder on the edge connectors on the Audio, Power and Main boards.
The Main filter cap has not been replaced.
Thanks in advance for the Help
