Just got done wiring up my Taito cabinet for Elevator Action. It was wired for Rygar, with a Tekhan wiring setup. I used the Rygar wiring PDF and the EA wiring PDF to rewire the cabinet.
i have 2 EA boards to work with. 1 works, the 2nd one has flipped graphics. However, both boards do the same thing in this freshly wired cabinet...they show nothing on the attract screen, but both accept credits, and do play the game, and when the game is playing, all i get are red and blue lines, that scroll upwards, as if it's out of sync. what am i missing here? i wired up the only sync wire to come off the EA board set, to neg horizontal sync on the monitor chassis, then to negative vertical sync, then i tried positive horizontal sync, then to positive vertical sync (turning off power with each wire swap). always the same results.
thanks in advance...
