Picked one up last weekend. I thought it was working when I drove out to pick it up but I think the guy selling it left out some details. I'm excited to have another game though, and I could always learn more about repairs. Right now he only speaks in sound test mode, not during the game, and I'm having some weird display issues. Those are the only two big things I've found so far... It's got new rottendog boards in it but I'm wondering if something is screwed up with them.

Tinkered around last night and kind of have a rough idea of what's going on some places, others are a mystery. I made a thread in tech but I figured I'd ask the Gorgar experts as well.
It's got a Rottendog MPU327 installed, but it's acting pretty strange.
It always starts up in the audit mode, but I can get through it by powering off and on real quick, but it won't save any settings I change.
The sounds work fine during the game, and Gorgar speaks fine if I hit the sound board test button, but he never speaks at any other point. I'm wondering if it's a speech board issue? I tried cleaning the speech roms and putting them back, but that didn't change anything. The 1 and 2 switches are both on and the balance knob is in the middle. Does anyone have any ideas?

Other than that, looks like it could use a good cleaning of the drop targets since scoring seems a bit weird and they don't always reset. Front ones are the ones that seem the worst, upper bank is a little sticky but seems to reset every time at least.

The 04 issue actually just ended up being a coin battery on the RottenDog board that needed to be replaced. The big issue now is the speech and display, but it's playable. I need to clean the front drops or something though, because they aren't always registering points or coming back up after being knocked down.

I think they're just getting stuck or something, a good cleaning would definitely help. I noticed that if I have the playfield raised and am testing the drops, they always register. So I'll need to clean them while I'm cleaning other stuff.

Thanks for the info, no doubt it will come in handy.

Speech is back, for some reason mine works configured with switch 2 off and switch 1 on. Is that the way it's supposed to be? I know I need a new set of speech roms though, as one of mine had a few broken pins during a clumsy repair session. Is there anywhere that sells them cheaper than ebay?

Was trying to look at this site last night but it wasn't loading for some reason. Seems fine now. These are way cheaper than the ones I saw on ebay, thanks for the link!

If anyone needs extra speech roms, I've got 2/3 of a set. IC-5 has a few broken pins but can probably be repaired. I just needed the set for IC-5 but ended up breaking the new 5 chip by mistake, and just repairing my old one. So if you need IC-6 or IC-7 or want a set and can repair chips (I did mine, but it's not my proudest fix), I'll send em cheap.
