Log Message:
Change the way that bit's are cleared in the InterruptPending register of
the 68901. Do this now by _assigning_ ~<bit_to_clear> instead of the
previously used 'andb ~<bit_to_clear>'. The latter caused a rwm-cycle that
caused a race condition to happen when an interrupt arrived between the
Read and Modify-Write.
Anyway, this solved my hanging keyboard problem.
