Well, the routine explicitly sets &FE6D to &A0 just before if set &FE6E to
the same value [LDA#&A0: STA &FE6D: STA &FE6E]; so I don't think this should
be problem, as the routine requires it. I've tried this on PCBBC and BBCInc
and both do not hang, but BeebEm hangs. Also: I doubt a real BBC would hang,
as the software works fine on a real Beeb!

Strange?

Regards,
Steve.

Trying to enable timer 2 interrupt.

Duuno.
