[GreenKeys] OT: New coffee-table book on punched cards

[Doug Alderdice]

Yes, 80-col cards were everywhere at one time.  I recall them coming in 
the NY Telephone bills to be returned with your payment.  When I started 
teaching HS in the mid-80s they would build the class report lists for 
grading by handing each student a stack of 80-col cards punched with 
their name and student # in homeroom one morning and then they'd give 
one to each teacher throughout the day, and we as teachers were given a 
stack of cards punch with course/class period info and we'd build a deck 
for each class period and turn it all in at the end of the day.  That 
continued surprisingly late; it was well into the 90s that we were still 
doing that.

The NYS Thruway (I-90) for eons handed each motorist an 80-col card when 
they entered and on it was printed the toll for each exit, and it was 
punched (round hole punches, so whatever system that was) with the toll 
entrance number and vehicle class.  You handed that over with your toll 
payment at your exit.

I cut my programming teeth with 80-column cards.  My high school had a 
comp sci program and an IBM 360/30.  We did all our programming in 
Fortran, though COBOL and one or two other languages were available on 
the system we had; RP/G, maybe?  I did a couple of programs in COBOL 
just for grins, but everything else was Fortran.  The one computer 
teacher used to write hall passes on the backs of discarded punch cards, 
which were of course extremely plentiful in the key punch room.
