On which hardware? ;-)

JFTR, the test succeeded on m68k, after 6 hours and 12 minutes of runtime
on an emulated Atari Falcon (ARAnyM hosted by an i7-4770).
So far I have no plans to run it on bare metal.

Gr{oetje,eeting}s,

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
