newer ones don't support the 386 at all
Minix 3.0 is even worse requiring a pentium as a minimum instruction set.
However, Minix 1.5 ran on XT class hardware (I had it running on a Tandy 1000sx around the winter of 1992? Or did I already own a 286 by then... Can't remember) and 1.5 added 68000 support. So theoretically you could run that today?
If you found a way to put a PDP-11 on the bus, real (good luck) or more likely emulated, I've run unix5, 6, 7 on simh emulator. I've also run *bsd on a VAX although that would be hard work.
