Centipede Mini Restoration
SirPeale:
I *think* my board is actually working, just not getting the voltages it needs to work properly. It's reporting an error "4" which usually means (and I've confirmed it with my meter) bad voltages for that particular ROM, an EAROM. I checked the +30V and was only getting something like +13V or something close. Once I recap the AR2 and mainboard I think I'll be okay.

Untested usually means not working. It's not worth the gamble.

It depends. Most of the untested boards I bought worked fine.
SW (bought as a spare set for my cockpit, though it was worth the gamble at €18 !!!)
MB
DK
Asteroids
Non working, sold as untested:
DKjr. (original)
Of course it's a gamble. Guess I was lucky most of the time. On every occasion I weighed price against risk. Worked out very cost-effective.
And I can do basic repair jobs myself on the boards.

Dude, you used up so much karma, you may want to avoid leaving the house for a few months. In my experience untested means no chance in hell of working. Even "tested and working" most of the time around here means "I played a game once and then turned it off before it blew again" at best.

I just called my boss to explain why I won't be working/leaving the house for the next 6 weeks ;)
Maybe we are more careful or honest overhere ? ;) ;) ;)
The SW, DK, Asteroids and DKjr. all came from Belgium or Germany. The guys who sold the SW and Asteroids didn't have "equipment" (read vector monitors) around to test them. I know nothing about the e-bay seller that sold me the DK boards. Both mentioned untested, one worked right away, the other I think may be a small problem.
I've also bought two boards advertised as tested and working (DKjr. bootleg (Austria) and Popeye(Germany)) and both work fine indeed.
Only the MB came from the US. Seller told me it was pulled from a working game when it got converted (poor cab) and was stored by the operator ever since. He thought it would be working, but couldn't/didn't want to test and also sold it as untested.
Yes I've been pretty lucky :)
P.S. Funny story about the Asteroids board. I got it because I wanted to have a back-up plan in case the Meteor PCB couldn't be repaired. I brought it over when I visited Andreas (who masterfully repaired the Meteor PCB) and asked if he could test the Asteroids on his cocktail. He had a look at the board, and a second look and said: "I'm pretty sure it will work". I asked why he though so. He said "I repaired this one". He recognized some parts (like low profile x-tals) he had replaced. I did buy it from a German guy and he wondered how the PCB ended up there. This hobby is a pretty small community, especially overhere in Europe :D
O and the board indeed ran fine. I still am thinking about putting it in the Meteor cab at one point in time, so that the games are switchable. Although I didn't notice any difference at all in gameplay, it could be good for having a kit on the original Atari board...

I did some asking around. Turns out the low voltage on the -30VDC is *only* for the EAROM, and it won't affect the graphics. So I've still got a board issue.
The sprites are okay, but the text keeps getting screwed up. I'll have to snap a picture.
And I either need to hook the coin door back up or put the machine on freeplay to see how it does. I really want to try it out!
