So roundies were even more highly anachronistic by 1968, the year ISTR being given as the last they were offered by Philco. Magnavox roundies selling new as late as 1970 is almost beyond believable, but that's another example that's been cited here.

A solid state roundie is about as likely as a tubed handlebar radio.

You'd have to be the richest kid in town in 1939 to have one of these...
