About 1995 I remember speaking to a guy who had programmed using a hand drill... He worked for a company that did industrial control systems and one plant (a steel mill I think) had a very old system controlling it that booted from tape. However, as it was very old the paper tape had long since worn out and had been replaced with a sturdy length of leather. He needed to make an alteration to the boot process so had to resort to the hand-drill.
