Raspberry Pi and an A500 expansion thought experiment

[kolla]

An obvious problem is voltage differences, the Amiga using 5V and the Pi using 3.3V, but that can be worked around. A general interface adapter that plugs between Amiga parallel port and RPi, offering a PLIP-like service (for example like PlipBox, only connected to a bridge interface on the Pi) on which you can run netfilesystem, mounting directories etc on the Pi. A bonus could behaving console on the Pi on the serial port

Port a modern Linux to 68k and run it on Vampire.

Rpi isn't particularly fast and connecting it to an a500 would not make it better.

An Arm chip on an a500 expansion is slightly more interesting, although it would have no software so a vampire is much better.

Modern Linux already runs on m68k, the problem is that Apollo Core is not a supported architecture, and most likely never will be. Anyways, a rPi runs in circles around Apollo core, so I don't see your point.

Plipbox already does this on the parallel port, the arduino also can handle the signal voltage of the Amiga.

The Vampires could really benefit from a simple USB host controller hooked to the FPGA, like the MIST has.
