1964 IBM 029 Keypunch Card Punching Demonstration [video]
- hilbert42 9y agoOh, my-my, a blast from the past—the KP-29 exactly as I remember it. We had a few 026s as well but the 029 was the much preferred machine. I remember many late nights coding FORTRAN statements on those card punches until university security chucked us out of the punch card room. Those IBM punches were very nice machines, they were exceptionally well engineered and very reliable, and they worked very well. Reckon we were some of the first hackers too. Back then, time was so precious on our university's IBM360 that we students were only allowed a few seconds processing time per job. Some of us figured out a neat solution to the problem which was to raid old discarded fan-fold printouts from garbage dumpsters at the back of the Electrical Engineering School that the computing department had used for its own purposes. On them, we'd find 'secret' $Job control codes that we put onto our own $Job control cards which we'd then insert surreptitiously into the batch job, this enabled us students to alter/increase the time given to any job within a student batch run. Back then, no one in authority seemed to think we would ever get up to such mischief.
