So is there anyone around that works on 6803's? I picked up an escape from the lost world over the weekend. It was advertised as working until it recently started blowing the 1A fuse under the playfield. I'm in the middle of testing coils and diodes, but noticed that machine won't boot at all. No error codes on the CPU, no flicker on the led at start up. Test points show 15 and 5 volts at the CPU test points. Displays are blank, except for a 1 on the first digit of the third display. Unfortunately, I think the previous owner may have done more damage trying to repair the blown fuse issue and decided to sell the machine when he couldn't fix it and my expertise in board repair ends here.
