Im having trouble with the sound circuit of a dig dug board. On the schematic, Im getting a bad ( less then 2v pulse wave) from pin 5 of 11C (82S25). The ram is good, Ive replaced everything in the chain forward (except the PROM 11A). I think the problem is somewhere in the adder or the flip flop..
Anyone had problems like this before?
