The Magnavox Odyssey was actually the first
home-based arcade video game console ever produced, hitting the scene in
1972. The second generation Odyssey, called Odyssey 2, was
released in 1978 & is familiar to more than a few of us.
There were really not too many video games made for the Odyssey 2, but
you can still get them. Ebay is about the only place you
can get Odyssey 2 stuff these days, and there are tons
of vintage video games available.
