I don't believe it, another classic added => Centipede ! FINISHED !!!!

No-one ?
I've got an old Atari 800XL here with all chips socketed. I think I could try the 6502 and Pokey of it in the Centipede PCB. Centipede uses a 6502A on 2Mhz afaik. The Atari runs at 1,79 Mhz but I'm not sure if it's a 6502 or 6502A.
I've been thinking about the glowing red button suggestion and illuminated track-ball. I think I may end up putting a GGG Ice button and Ice trackball. This way, it looks pretty original when unlit, but very special when lit :) Best of both worlds. I will use a leaf on the end of the ICE button though, NO microswitch, can I still light it up OK with the leaf ?
Two pictures: What a mess under the bezel ! I cleaned the monitor and I am 100% sure this was the very first time in it's life !
This sticker was put on the bottom of the bezel.....

yeah....I think it's due to the extreme violence of shooting that poor centipede and spiders and scorpions :laugh2: :laugh2:

Arcadeshop has a lot of stuff for Centipede, including the monitor bezel, CPO, etc. I don' t know if they can ship it to you, though.
You might check for bulging electrolytic capacitors on your PCB. Some of those go bad after a while. Try looking at the schematics to see what parts of the board control sound, and concentrate on those areas.
Also, you might want to consider changing the power supply for a modern switching power supply. Old power supplies can be flaky and there might be more hacks in the supply than what you have discovered already. It's also possible that your monitor isn't getting power, but the monitor might also just be dead.
Try consulting with Ken Layton regarding other repair hints.
RayB:
His voltages are all good. Why would you recommend installing a switcher?
For durability, a Bob Roberts rebuild kit on the AR-II and a new Big Blue will keep it running for many more years. (Plus the "Sense" mod that some recommend).
