hi,
I hope someone here can help me.
First had a sound problem with my outrun - just happened suddenly.
The revving sound of the engine became garbage and also sound comes through 1 speaker.
Eprom tests report no problems, sound test plays all samples fine..
Anyway I think I have traced this to the sound board - the speakers themselves are fine and when I switch the connector on the main pcb that has the sound output 180 degrees (so left and right channels are switched), its still the same problem and same speaker that doesn't work. So therefor I suspect the sound board as the input changed but the output didn't..
Second problem - after taking the pcb out of the cabinet to push down on all eproms, I now also get some garbage in the screen :-(
See picture at http://www.flippers.be/temp/outrun.jpg
there are a lot of rows of dots that flicker on the screen..
when the outrun logo shows on screen, part of it is also in a flickering dots pattern..
Any idea what causes these dots and how to fix it ?
(or anyone who sells working boards ?
or anyone in Europe (pref belgium, netherlands) who can fix these boards ?
ciao,
Aeneas.
