BZZZZ! Wrong answer.

First of all, what game are you running? If StarTrek, you need a Universal
sound board and a Star Trek speech board. The speech board will have 6 or 5
pins.

Second, even if that was a speech board, you have the speech board connector
upside down.

Thanks for the picture, though! I've been trying to explain it in words to
some people.

So it should be like this for Star Trek

However, according to my records, you ordered a Speech board populated with
Zektor, so if you are trying to run Zektor, replace the above StarTrek speech
board with the Speech board I sent you and replace the Universal Sound board
with the Meatball sound board. Of course, unless you have the special chip,
this won't do you any good (hurry up, David ;-))
