1975 Atari Crash 'N Score Restoration
RetroACTIVE:
I'd certainly scan the artwork and have it re-printed.... The artwork is very simple and could be a vinyl decal and look just as good. You could easily do vinyl decals on the tinted plexi too. I would get some white melamine from Home Depot and use it for the sides instead of paint.
Your Defender power supply is pretty specific... I would just research this game's requirements and go from there.
ChadTower:
The good news is you don't need plans. There is enough there to get your own measurements or even make a cardboard template from which you can make a router template. Is it solid enough to get scans of that artwork to be cleaned up?
Also consider that you don't have to make the new cab identical. It won't be original no matter what so you can choose to make something different to your own tastes. Just be sure to capture the original spirit and you'll still be all aces with us.

I found a full service manual for it, so I'll be able to tell what voltages are needed where. The voltage signals needed are probably 5V and 12V, so if nothing else I can probably use a PC power supply and eliminate that huge, dangerous transformer. I've worked on PCB of "The Real Ghostbusters" that had been fitted to an OLD 1980's PC case this way.
That is, if I even NEED a power supply. This one is supposed to work.
As far as the cab goes, I'm going to try to be specific and build the new cab as close in every detail as possible to the original. It will be the original game in a replica cab.
ChadTower:
That's a TTL board. IIRC, A lot of those mid 70s Atari boards take in an unregulated 5v and convert it on board. It might even be AC coming in but I can't remember that one for sure. I do remember that my Tank II PCB takes the voltage right off the transformer so that's probably the case. You might be able to use a PC power supply but you'd have to find the spot where it is finally a clean +5v (and there might be a -5v too) and hack the PC +5v into that spot.

Pretty sure you are correct Chad... the big power transistor and filter caps on the pcb along with the transformer sitting all by itself are all pretty good indicators ;)
