I have a bunch of prototype (no solder mask) and/or development (modified for game development and debugging) circuit boards from the earlier Williams video game era.
I have:
-- 2 Stargate/Robotron/Joust type CPU boards
http://backglass.org/williams/proto_boards_01.jpg
-- 1 Stargate ROM board with production ROMs, 4 Robotron/Joust type ROM boards, and one interface board from one of those games
http://backglass.org/williams/proto_boards_02.jpg
Note that one of them has a really early revision artwork part number:
http://backglass.org/williams/proto_boards_03.jpg
-- 2 of some sort of interface board I can't quite identify. The DB25 connector on the back looks like something that was only loaded for development purposes.

-- 3 Sinistar type ROM boards set up for debugging/development. One still has the debug EPROM loaded, plus 9 "pigs" - these were the 2 static RAMs soldered on top each other, plus a logic chip, to allow RAM to be plugged directly into the ROM slots. I'm not sure I've ever seen any of these outside the walls of Williams before... anyone? A couple of them have prototype serial number stickers.

-- A power supply and sound/speech board setup on its original mounting plate. Prototype serial numbers, but I can't for the life of me figure out what game it's for ("PB" ?) Was apparently leaning against a wall in a basement that took on a little water, as you can see there's some corrosion along one edge, worse in one corner.

Needless to say, these are all untested, some of them are even marked "BAD" and while mostly complete I am not guaranteeing that every last part is on them. These would be of interest to someone for historical or display value, and it would simply be a bonus if they could be made to run. Don't buy them if you're just looking to get your Stargate warehouse find running
I'd like to get $500 for the lot. I'm near Chicago, but I'll pack them up and ship them anywhere in the world that you'll pay all the shipping costs for! If you need more specific details on anything just ask.
Thanks,
Duncan
