Ever hear of a 2-inch Trinitron?

[Pete Deksnis]

A guy responded to my site recently and mentioned a recollection of a 2-in. Trinitron:

"Sony once made a mini portable TV with the worlds' smallest Trinitron
color CRT. 2 inches! The entire TV would fit in a shoebox. The screen
was on the end. A green bar on the screen pointed to the channel
numbers printed beneath the screen. The TV ran on 6 or 8 C batteries or
the included AC adapter. It was Hi-Tech for 1980!"

Can anyone back up his story?
