I have finally gotten my Flash pinball working (except there is no sound). Pinrepair.com's manual mentions testing the test points for proper voltage, but there are no obvious points to test and the manual doesnt show the test points (at least as far as I read). Anyone know where to test the voltages on these boards
It is a Type 1 board with a SOUND1 rom
What I'm getting is no sound during game. If I press the test button on the board, it repeats the same sound over and over again (which at least indicates I'm getting some of the correct voltages), however I believe it is suppose to cycle through all the sounds.
Any suggestions?
Thanks,
EDIT: Is there a diagram of the layout of this board anywhere? Also, I do have an eprom burner, thought I might try to read the soundrom #1 chip but the mfg of the chip isnt listed in my eprom software. I have the correct file to load onto an eprom, but need to get a compatible eprom for the socket. Anyone know the specs of that eprom so I can cross reference it?
Thanks again.
