RGBeeb VS PiTubeDirect

awww - https://github.com/dekuNukem/RGBeeb/raw/master/photos/torch.... was my second ever computer. never thought i'd see one on HN; i miss the yellow-on-blue wonders of CPM :(

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.

IMHO this makes the PiTube Direct project perhaps even more impressive: it attaches emulated vintage microprocessors to the BBC Micro Tube interface, implementing the Tube circuitry in software.

BBC Micro/Master - PiTubeDirect - emulates a load of second CPUs for for BBC. Lets you run CP/M, DOS.

It's a shame he desoldered the tube connector. He could have used it for a pitubedirect (https://github.com/hoglet67/PiTubeDirect)

There's a similar project for the Acorn BBC Micro called PiTubeDirect, which allows the Pi to emulate several different CPUs, while connected to the BBC Micro's "tube" second processor slot.

(The BBC Micro itself was quite remarkable for supporting multiple processors, which did not have to be the same architecture as the host 6502.)

If you ever do want to play with Tube like this, I've heard of https://github.com/hoglet67/PiTubeDirect - not got around to trying it yet - but I want to.

I expect the tube version will be for 6502 3mhz, but worry not! https://github.com/hoglet67/PiTubeDirect/wiki
