And when you had a software bug and got stuck in a loop with
interupts disabled (The on/off switch generated an interupt...) you
couldn't reboot the machine. If you unplugged the Lisa, you stood a
large ( >> 50%) chance of trashing your hard disk... What to do?
Apple SOON added a hardware reset button!
