The information on these pages regarding Remington
Rand, drawings and the photo's were provided
The 90 column card used round holes a 1 & 9 = 2, 3 & 9 = 4 etc. Various combinations of numbers made up the alphabet. The card would enter the inbox. The pins that entered the holes would lock up force wire up in a wire unit (the equivalent to todays program) and the process would continue from there.
Punch cards were printed as well to show where certain information went.
