I have a Microvision (in not so good shape, I don't
know if it's
functional or not) but never heard of Adventure Vision or COSMOS.
In the spring of 1980, Atari showed COSMOS at a press
conference in New York. It was designed by Al Alcorn and was a
'holographic' game. It's my understanding that it basically
disappeared after that. I've never seen pictures of it or it's
game(s).
