Two other favorites of mine, wondering if anyone knows of a link to them ... The Dark Emitting Diode (DeD) - I think this was a magazine article. The devices were produced by taking ordinary LEDs and subjecting them to 120VAC. They were reported to be useful as power-off indicators, and boasted a manufacturing yield of 100%. The Vacuum Tube Modem - also a magazine article (I think). Reported to achieve incredible speeds by taking advantage of nonlinear behavior intrinsicto the device. Also reported in the same article - a Russian tube-based microprocessor, based on a single tube. It was called the PentiumProtubeski, if my memory is correctly functioning in a write-read capacity. If you've got links to those articles, they'd be greatly appreciated.
