Do Atari Cosmos schematics exist?

[+Propane13]

I see the circuit board here:

http://www.atarimuseum.com/videogames/dedicated/cosmos/cosmos.html

 

I'm curious if any schematics were found, or if anyone took some high-def pictures so that schematics could be drawn up.

Are you looking to re-create this possibly? Atari History Museum would probably be the best place to look but am sure Curt gets a stampede of requests all the time as it is overall.

If there is a schematic, only Curt would have it and as Clint Thomson wrote: "...Curt gets a stampede of requests...", so

you still can ask him but it may takes quite a time before getting a replay (or until Curt read these posts).

 

But there a few documentation you can read until then, check US Patent #4,421,317:

http://www.google.com/patents/US4421317

 

And also this patent #D,269,087 (cartridge design): http://www.google.com/patents/USD269087

 

As for the CPU, it uses a COPS411 (same as Entex Adventurevision) in case you were wondering

and all 8 games are already programmed in the CPU, which are:

 

* Asteroids
* Basketball
* Destroyer (aka Sea Battle)
* Football
* Outlaw
* Road Runner
* Space Invaders
* Superman

*** Dodge 'Em - Never programmed/produced ***

The board picture shows a COP444L. According to Sean Riddle, its ROM can be dumped:

This would allow another micro to be programmed in its place. After that, a replica would be a trivial project.

 

Anyone got a Cosmos CPU they'd be willing to dump?

I think there are only 2 in existence. Curt's, and the one that the original programmer has.

Hopefully one of them can be convinced to do the extraction.

Entex seems to have used a COPS411 for sound only, the Adventurevision CPU was an Intel 8048. The Cops memory layout explains the eight games in the cosmos.
