Summary
[edit]DescriptionIBM Card punch (51333058324).jpg |
I used these (or something very similar) while at University in Hull (1975-78). [ update - it was indeed an IBM 029 card punch. I found the "Elementary use of the IBM 029 Card Punch" instructions in a cabinet in the garage from Hull Univ. Also here <a href="https://twobithistory.org/2018/06/23/ibm-029-card-punch.html" rel="noreferrer nofollow">twobithistory.org/2018/06/23/ibm-029-card-punch.html</a> ] I think I also used them at the University of Surrey before then but mainly we used mark-sense input sheets like this… <a href="https://twitter.com/kenshirriff/status/1337855283276570624" rel="noreferrer nofollow">twitter.com/kenshirriff/status/1337855283276570624</a> I used an ICL 1901 while at school. We would have to wait days to get the results back :-) While at Hull I used the card punch machines to program their ICL 1904S. Mainly in FORTRAN and Algol 60. Like the ASR33 Teletype (see later) I liked the clunky electromechanical sound they made :-) . I had loads of punched card decks (some several inches deep in cardboard boxes) but only kept one set I think - an Algol 60 program I wrote in 1977. |
