It used to be a 486 – the 33 MHz version I paid about £100 for in the late 80s, not long after Intel brought out the 486/50 and the price of the 486/33 dropped.

It was the first CPU in what was my main PC for some years in the 90s, and ended up being replaced by a 486 DX-2/66 and then the wonderful pin-compatible Cyrix Xc5x86/100.

Now it's a Pentium/133 from a PC found in the street with almost everything else ripped out. Even more gold pin goodness 🙂
