My Flash Gordon says "Emperor Ming a KWAAWWK PFFFT BUZZ FARTTTT", which I'm pretty sure is not correct. I'm not able to repair the board (tried new ROMs, caps, etc).

If you have a working S&T board please let me know! Even dirty is fine, as long as it works. I'll clean it up and replace caps and pots if needed.

Hopeless bump.

I may have one last working one, I will take a look and let you know.

They are hard to come by - even in marginal condition (I have one I attempted to fix by replacing caps with no-joy).

You might try K's Arcade - they usually have some they've rebuilt (and currently show as in-stock). I bought one for my EBD and worked great.

its time to send your one in to a board magician and get it fixed. Dont know who in usa but coinopcauldron above is likely a great choice

Thanks, much appreciated!

I saw that one at K's Arcade, but my face exploded from sticker shock.

I think you guys are right... if someone doesn't dig one up around here, I'll try having it repaired. Thanks!

Did you replace the sockets for the IC's? The board is working you are missing a data line or two. Most likely the sockets, connectors, bad outputs on a PIA, etc.

I have a partially working one, never tried to debug it. LMK if you can't find anything else and need one.

I haven't changed the sockets, but I think you are absolutely right about the missing data line. The bad speech is always in the exact same place each time. The high cost of a new board surprised me, so maybe I should give this another shot. I have a Hakko 808, so it would probably be fastest to socket all the IC's and then if that doesn't work, start swapping IC's until I find the bad one.

There's a new one listed on Ebay if you put in Centaur pinball for the title. Or you could click on the link below. Hope that helps.

Oops, got the wrong link. And I just realized that the "Squawk-n-Talk" link is gone. My bad.

Ok, went through all my S&T boards, none work and I do not have time right now to repair. I will offer this advice if you just decide to go the shotgun approach on you decide to cut all chips and socket. If that does not work, no one will attempt repair and in addition to the original problem, all your solder work will now be in question.

Aw, here's one. Good luck, I hope it works for you.

I'd start by rebuilding the lower left connector on the MPU first, then socket the TMS5200, the ROMS, then the PIA.

Check the board for normal operation after each step.

Is the TMS5200 corroded or have black crap on its legs? If so VERY gently try and sand it off. Be VERY careful when removing it from the socket they are extremely fragile when corroded or tarnished.

You think an MPU connector could cause this? I guess I imagined the MPU would instruct S&T to produce a particular sound, then S&T would handle building the audible sound and just "pump sound" out to the speakers.

I'll check the TMS5200 for black crap.

Appreciate the help, thanks!
