The same chap has also built a device, sold commercially, called
ViewFinder which allows certain AGP graphics cards to be connected to
the Acorn RISC PC's podule bus, complete with accelerated RISC-OS
display drivers. Quite a coder.

Closer to home for CP/M, there is a CF interface for the Z80-based
Sinclair ZX Spectrum:

This page links to schematics, firmware and so on. I believe CF cards
are quite simple to interface to, and with an external PSU, the same
interface (with slightly modified firmware) can also drive IDE hard
