A sample computer card that was used to input data into Wyoming’s first commercial computer, an IBM 1401 card system, installed in September 1960 in the offices of Pan American Petroleum in Casper. Vince Siren, who was the first full-time computer programmer in Wyoming, told me the computer was about 4’x4′ and stood about 7′ high. It had 4,000 characters of memory and was connected by cables to a card-reader punch and to a 132-character printer. Vince gave me this card and told me the story many years ago after a “History of Wyoming on-the-road” tour.
