Few people have heard of it, yet many consider John Blankenbaker's KENBAK-1 to be the first commercial personal computer.

Koss introduced these headphones over 40 years ago, and they remain affordable favorites to this day.

A Mysterious Sony Radio

Sony TR-8 micro radio

Shav La Vigne recently sent us some photos of a tiny Sony TR-8 radio with a plea for more information. For once, we didn't have much to say. All we know is that it was Sony's first micro radio, released in 1963.

Sony managed to cram 8 transistors onto the tiny hand-soldered circuit board in an astounding display of miniaturization for the early sixties. However, I suspect the tiny size made it extremely expensive to manufacture.

If you can tell Shav more about this diminutive receiver, please leave a comment.
