I got a Squawk & Talk board for my UDOT and I'm having a some trouble getting it to work in the game. The board was from a Bally NFL Football, but I burned the EDOT roms for it (U3, U4, U5). I hooked up everything per this guide:

but it does not work in the game.
My power board is working fine, so I have a switcher powering the S&T board with +5 & -5. I ran the lines from the SSIO board to the S&T board per the schematic and jumpered pins 8 & 9 on the SSIO to put it in EDOT mode. Hooked up the S&T output to the SSIO board and I get speech when I press the test button on the S&T board. It goes through all the different speech lines and plays a sound effect at the end.
However, in the game (test mode or otherwise), the speech does not work. I just get a small popping noise when it tries to play any speech. I did not get the popping when I didn't have the S&T installed.
I read up on JeffC's thread, but I didn't see anything that I was doing wrong: http://forums.arcade-museum.com/showthread.php?t=63259
Anyone have any ideas?
