My oldest unit was

that I got from a garage sale for $5. I had an Intellivision and
a Color Computer 2 at the time (1984) and I was FASCINATED by
retrogaming consoles, like the Odyssey 200, which was made in
1976 when I was 4 years old. It had corroded batteries in it,
which I scraped off (burning my hands a little because the acid
or base was still strong) and 12 year old Ken Udut got to play
with a console that was already ancient video game history by
then. By the time I was 17 (1989), I thought video games were a
dying medium and I switched to "serious programming" and BBS's
and the Internet instead of designing/marketing video games
which is what Iwanted to do. I was wrong but no regrets.
