Simplicity is in the eye of the creator
By James Grahame
"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.
