Lusting for those early microprocessor days? Here's a site guaranteed to sate your passion.
My wife and I joke about our “adult” magazines. For her, those are the publications about beading. For me, they’re tool catalogs and Fine Woodworking magazine. The latter I peruse as avidly as a teenager gazing at an illicitly-procured Playboy (or, whatever passes for those sorts of magazines today).
And yes, I do read the articles.
Then there’s processor porn. Do you want to see thousands of pictures of naked CPUs? Stop by the CPU Shack. In addition to extensive archives of processor pics, the site weekly struts out different bits of silicon technology from the past. As in the aforementioned Playboy, the CPU of the Week gets a complete description. For the high-minded who scorn prurient pictures, the site does have articles which are well worth reading.
This is a picture of a hot processor from CPU Shack. It’s Intel’s 3002:
I well remember this device. The description says this nerd-magnet was born in 1973, which is astonishingly early. It’s a bit-slice processor – a two-bit slice of a computer. String together as many as you want to get whatever bus size is needed. Strange, huh? AMD competed with the 2901, a 4-bit slice, with which we designed some high-end graphics gear long ago. I don’t know how popular the 3002 was, but the 2901 gained wide acceptance.
Then there’s this sweet thing, a 4004, the first commercially-successful microprocessor:
