Looks cool. I'm not courageous enough to try though. I have written a
few FPGAs with VHDL/Xilinx but that's as far as my knowledge of
numerical electronics go so the limit of my "big picture understanding"
is that I have some layer that can execute a reduced instructions set
(eg. x86).

As for the hardware to run Minix3, I am lucky to have an old Dell
laptop with one of the few supported ethernet chipsets, but otherwise
emulation (with QEMU) works fine, with sufficient performance if your
CPU has VT-x capabilities.

I haven't had much time to play with it recently. I was disappointed
by the move towards GNU tools (glibc, gcc) but I have to admit that
ack is old and lagging behind modern compilers.

I wonder how hard it would be to build a "suckless" Minix3
distribution with tcc / musl...
