A PDP-11 program card
I was trying to find some data about the PDP-11s instruction set, so I could look up the bvc and sxt instructions in this old snippet. After a quick look around google, I stumbled upon a page talking about an emulated PDP-11 on SIMH; and the idea of keying in a program one instruction and one address at a time on toggle switches.
Then I saw this picture referenced, and thought it worth posting for anyone old enough to have programmed when "cards" were integer to the process:
"Front" Side of a PDP-11 Programming Card from 1975
Thou shalt check the array bounds of all strings (indeed, all arrays), for surely where thou typest ``foo'' someone someday shall type ``supercalifragilisticexpialidocious''.
