This one's been around for a while:

Tynemouth Software do USB keyboard controllers for the keyboards of
various 80s micros, including the BBC:

I wouldn't want to dismantle a working machine to do this, but it was
common enough back in the day -- I converted a dead Dragon 32 into a Z80
machine in the early 90s, and I was given a terminal keyboard fitted
with a ZX Spectrum motherboard at one point. It certainly seems a better
use for (say) an Electron with a dead ULA than just sitting around
gathering dust, and it's easy enough to do it reversibly these days.

I've occasionally wondered about building an ARM workstation inside an
IBM Model M keyboard...
