Hello, my name is Andrew Wylie and I live in Purley, England, not far from London. I call myself 'Mister Transistor' because I have been interested in germanium semiconductor devices since about 1980, when I first realised that such things were becoming rare. I am especially keen on point-contact transistors, the first kind ever made. Nowadays there are a few other sites that specialise in such devices from the USA, so I emphasise my types from elsewhere in the world, although I do have many rare and historic US examples too. I also investigate integrated circuits from the 1960s, prior to the Intel era.

Another technology that interests me is bubble memory, a weird type of device from the early 1980s.

I'm also interested in early integrated circuits (way before Intel, there are *lots*).
