Slightly O/T.
Can the PI be rigged as an accelerator?
What's to stop somebody wiring up the accelerator port in an A1200 to the Pi via USB (or faster bus - obviously may need some sort of breadboard inbetween) and passing the instructions to an ARM 68000 series emulator such as
http://notaz.gp2x.de/cyclone.php (this emulator is 68000 only)?
Obviously FPGAs are better for the purpose but technically I can't see too much trouble apart from:
- Conversion between the trapdoor connector to USB serial will likely need custom PIC work.
- Custom software glue to pass the USB instructions ARM side to the relevant emulator API and return results.
- Emulator may need modification for access to the Amiga chipset and chip ram, as opposed to ARM ram, via USB
It may be a tad slow... and now I've written this post probably complicated.
