Zilog Z80, 1976 – 2024.

Over its 48 year life, the Z80 found its way into inumerable devices.
It's perhaps most famous for being the CPU used in the ZX Spectrum, but could also be found as a sound co-processor in the Sega Mega Drive and SNK's Neo Geo arcade boards, among others.
I remember finding one inside my first HP inkjet printer back in the late 90's, and my parent's Sony Trinitron CRT, handling the on-screen menus (and teletext).
