Hey Ray, great job !!!! Any "finished" pictures ??
Why didn't I find this thread earlier ? I envy you, you always seem to have (working) PCB's on the same cabs we have

(Remember Domino's)

I also wondered about the marquee retainers on my Centipede....what a stupid idea to use rivets !
I had the same thought as Arcadefever, I have exactly the same bit set here (kinda forgot to give it back to my former employer....sorry

) and I thought one of those would make it possible to remove them...good I read this !
I must say in general that Atari has the wost "service-friendly" cabs from what I have here so far.....I mean, you need to remove the staples of the carton bezel to get the monitor out !
(well you know what really happems, the bezel just tears and the staples stay in....not a big problem though, it's out of sight and indeed they're not needed.)
Than the power supply......a whole range of weird voltages are required...They are all fine on mine....but the PCB doesn't work....

Wanna trade your Centipede PCB for all the Dominos parts you want

For now, I won't do much on the Centipede...Gotta get the last things done on the Galaxian, and I just won a PCB set for my Mario Bros. It's untested so please, let me be lucky for once so that it's working......
