PiTubeDirect VS bmc64

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

Latency.

It doesn't matter how fast your emulator is, throughput-wise. Your operating system (and other stuff) sits between it and output and input devices. And usually adds multiple frames worth of latency. There's ways to improve this, certainly, but you won't get that experience "out of the box."

Now, it's also possible to accomplish this by running emulators "bare metal" or "close to the metal" like my friend Randy did with his BMC64 project: https://github.com/randyrossi/bmc64

Check out BMC64, it runs on a Raspberry Pi and you can attach a real C64 keyboard and joystick ports to its GPIO if you feel inclined to. I have a C128DCR keyboard attached to mine with two joy ports and real C64 joysticks.

BMC64 for Raspberry Pi. I haven't tried it, but it sounds very cool.
