OK - you know who you are.

A few of you spent your teenage years in a bedroom packed with radios and TVs. What might seem strange to most people is the picture tubes were pointed towards the wall and horizontal hold meant touching the high voltage rather than adjusting the picture.

These days it is difficult getting parts for projects. Radio Shack is both disappointing and expensive, but there are junkyards. For those of you who can tell the difference between 110 and 220 VAC by touch - this one is for you!

continuing with the theme

Greg sent a link with some remarkable items. Most remarkable is the world's first IC - the Loewe multivalve from 1926. I really want one of these! It turns out the German's taxed radios by tube count ... a radio with a tube count of one would be very desirable, so 3NF encloses three triodes, two capacitors and four resistors in a single glass envelope.

Many other treasures lurk on the page. The very clever glassware section makes mention of the Selectron from RCA. A 256 bit RAM with a 20ms access time. It dates back to the early fifties and was used in the Rand Corporation's Johniac. (Note .. the Johnaic is mentioned near the bottom of the link. Rather than going directly there, you should read the full page).

And then some items are the stuff dreams are made of for people who buy surplus hardware.
