I've tried to run pcsim(from an old minix distribution) on a MC68000
under UNIX. Had similar effects!

The reason for this is, that the simulator was written for a VAX
(a little endian machine) to simulate the 8086 (also little endian).
The Motorola MC680xx's are BIG ENDIAN! You have to change the
simulator to take that into account.
