As I try to make progress with this project Flight 2000 it’s time to dive into the vocalizer card.
Read a bunch of posts and with the help of another working card have gotten this far:
Game ROM and Speech Chip are good and the game will talk with the working board. So the MPU and SB-300 sound card are set correctly for speech. The project vocalizer board won’t talk in game play or solenoid tests but sounds still work.
On the project vsu-100 I have 5 volts and -10 volts at the test points. I need to order capacitor kit to replace originals.
In the meantime are there other measurements I can take comparing the working and non-working cards to see if there are other parts I need to source?
Here are front and back of the non-working board. Thank you.
