PiTubeDirect
Bare-metal Raspberry Pi project that attaches to the Acorn TUBE interface and emulates many BBC Micro Co Processors
If you were to do it all from scratch I could agree, but there are projects to allow baremetal code to interact with the different hardware on the Pi (works on a bunch of different models.)

See also, PiTubeDirect[1], which runs on a Raspberry Pi which you have plugged into the second processor port of a BBC Micro[2], and turns the Pi into emulator for a number of different processors, notably an arbitrarily fast 6502, a Z80, or an 80286.
