Vectorbeam was a spinoff company from Cinematronics. The Vectorbeam
hardware was 99% the same as the Cinematronics hardware. As such, I'd
imagine that the Vectorbeam program was 99% the same as the Cinematronics
program (though I can't say for sure, since I've never compared the two
bit by bit). I think the reason that the initial poster said that Space
Wars was "public domain" was that the original Space Wars program was
written on a PDP-? computer. Larry Rosenthal saw it at MIT, and he proceeded
to make the custom TTL processor that both Cinematronics and Vectorbeam used,
so that he could play Space Wars at home in his garage!
One possible explanation for why both Cinematronics and Vectorbeam both had
Space Wars might be that Larry Rosenthal retained all rights for Space Wars.
So when he jumped ship to Vectorbeam, Vectorbeam could also build Space Wars.
