They say, however, that DNA data-holding strategies proposed in the past still offer some advantages—such as roughly 12 to 50 times greater storage density than the punch-card technique.

UChicago researchers created a ‘quantum-inspired’ revolution in microelectronics, storing classical computer memory in ...

Ah punch cards. I remember those days. The best (maybe only good thing) about them was that if you dropped a card deck you sometimes had the “opportunity” forced on you to rewrite your program.

Worked on the IBM 029 card punch machine which could store 2 programs and then the cards data entry was verified on the IBM 059. When we went to the IBM 129 we thought we had surely been blessed.

But for more than a century, punch card automation was perhaps the most remarkable longevity of anything in computer science. Nervous System: How Punch Cards Brought Us to Our Census Newsletters ...

When aerospace engineer Bob Brockman joined UDRI in 1973, calculations were performed very slowly by massive computers with very low memory, and programming and results were never in the same day. Bob ...
