Wayne,
The "opcode 1111" guru message indicates that you were trying to run a
program that was expecting to find a coprocessor and didn't. Opcodes that
begin with a binary 1111 (hex F) cause so-called "F line" exceptions on
680×0 processors. Motorola has reserved the "F line" exceptions to
implement coprocessor instructions.
