Hi all!
Been trying to get this sound board going. All I get is a kind of air/static sound from the speakers that can be made softer and louder with the volume pot.
I believe the board was pulled from a LW3 and I'm fitting it onto a star wars. I have burned the right EPROM sizes for U17 and U21 (27C4001 and 27C2001) and adjusted jumpers W6 to W7, also have burned a 27C256 at U7.
I have tried shorting the volume pot to see if that was a problem but so far none of the speaker tests or the boot up sound plays.
I'm starting to think it may be a bad chip, though I don't know what I am to check for with a logic probe.
Anybody got any ideas?
Thanks!
Ben
