May have a bad 74LS399 on one of our Battlezone boards and they seem pretty hard to come by. I found a couple small online parts stores but I'd rather not deal with them if I don't have to. ;)

Anybody have one or two extras they'd sell? If so, PM me please. :beerchug:

Hey Jeff,

PM me your address again and I'll mail you a couple.
 
Just installed the new 74LS399 and the problem has been solved. :fest30:

Thanks again Craig for the chips... you are truly an absolute asset to this hobby. :rock:

And for future "search" reference, one symptom of a bad 74LS399 at H8 is Zout never being blanked. You also can have full brightness one time you turn the game on(at which Zout will be ~1.5v steady). Then the next time you turn the game on it will be very dim(at which Zout will be ~.6v steady).

It could also look like D0-D3 on the 74LS175 at F8 is getting stuck high or low.

Thanks again Craig!!! :beerchug:
 
Fantastic!!! :cool: I'm glad that's all it was. Play a couple of rounds for me!
