Big deal. The current OS will crash if a programmer writes faulty code,
too. As it has been said many times on this list already, the z80 was never
meant to be powerful enough to be able to trap writes to bad memory
locations or in this case setting the interrupt mode to mode 2.
In any case, good luck.
