...fat fingers, hope this doesn't post twice.
A logic probe will show constant activity once the board boots & the machine is in attract mode on the outputs of these chips...
U6, 7 thru 10, 12 thru 15, 27 thru 35
U (Z) 18 thru 20 & 11, all outputs
U (Z) 12, at least pins 2 & 12
U (Z) 14, at least pin 10.
Are any of these stuck high or low?
Quoted from scoots:no one's ever recorded the logic probe readings on a functioning board? how about just U6 when all the scores are sitting at 0?
pretty please?
