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.

Simplicity is in the eye of the creator

H-P 9100A

"Solving even transcendental equations now becomes as simple as typing your name." Quite true, if your name is Mr. Inverse Tangent. This crushingly complicated H-P 9100A scientific calculator retailed for a whopping £2,448 in 1969. Those who chose to wait another three years were able to pick up an HP-35 handheld for a much more reasonable £200.

Thanks to Chris for featuring this and other brilliant stuff from the May 1969 issue of SCIENCE Journal at Cyloblog.
