Hi,
After making the test chip i found that there was one of the output pins on the PIA chip that was dead.
I had to cut the chip off the board, de-solder each leg and then put on a piggy back socket. I put in a new PIA chip and the game started playing some sounds.
Now I can go into the sound test diagnosis and hear the tones play correctly and the music play correctly.

I still have a sound problem through. The voice sound tests do not sound correct.
They are a garbled digital noise.
I think the BSMT2000 chip is the one that plays the tones but can not see how to trace why the voice chips are not working.
Does anyone know how to test the operation of the U17 and U21 chips?
It looks like they all share the same bus as the BSMT2000 and go into U24 and U23 parallel to serial chips and then to the D to A.

Thanks  Rich.
