Thanks, yes doing everything (also the CPU) on the FPGA is possible. But even the fastest FPGA M68k (Apollo 68080) are limited to ~100-150MIPS. The Opensource FPGA M68k (e.g. tg68k) achieves about 20 MIPS maximum. So adding a Pi with emu68 boosts the FPGA system to 2000+ MIPS :)

PocketStorm is alive :) A small,cheap FPGA doing the Amiga chipset, Pi4 with EMU68 does M68k JIT .

Boards ordered. Let's see how many errors I did :)

Indeed, but the memory controller needs some adjustments for AGA first.

A little side project. I took Till Harbaum's nanomig, stripped it down a bit and added a PiStorm interface. Prototype is running on a SipeedIO Tang Nano 20k, currently designing a better PCB for it. Nice cheap, insane fast hybrid emulation (FPGA + Emu68 JIT on Pi4/3) Amiga :)
