Well, there doesnt seem to be a lot of explanation out there on the Black Knight board....at least I havent found it. For example, what are the DIP switches for?
I picked up a black knight pinball. It has some power issues, namely that it does not have a system 7 power supply in it. It has a system 6, and the +100V leg doesnt work. I think the transistors are bad on this leg. I ordered a new power board.
So, I wanted to test the sound card for now, since it has its own supply. My sound board has the voice board on the left side of it. When I push the diagnostic button on my sound board, it indeed makes sound effects. However, it only makes sound effects, and no voices. It actually plays 3 successive sounds in a continuous loop.
Can anyone explain this? Are all the sounds on the main board, and the voices on the board to the left? If this is true, I assume that my voice board is not working. But, I am in doubt that the main board only has 3 sounds.
I have reflowed all the joints on both the sound boards. I have not tried to re-seat the ribbon cable between the two boards yet.
Any ideas as to what is going on?
DIP 2 is pushed in on the right, and DIP 1 is pushed down on the left.
