We also had a Y1970 problem.  Our punched card systems used a
single column for the date.  In 1969 we discovered that a lot
of programs would not work in 1970.   To solve this, we used the
Eleven punch for 7, the Twelve punch for 8, and a combination of
the Eleven and Twelve for the 9, thereby creating an early version
of the Y2K problem.
