OK ... My turn
In 1958, I graduated from a Marchand (sp?) 100-key calculator to an IBM-650 to help me finish a physics lab data reduction. They had just retired the Card-Punch Calculator (IBM 605, I think). I wrote in BLISS (Anyone remember that), and o-so-well recall the +70 1951 9999 setting, and all that board-wiring. Thence, on to a Datatron 220, IBM-709/7090 and 1401, dabbled with some PDP's and Tandem Non-Stops. I've been running Linux at home for my gateway for the past 4 years. It's a lot of fun.
The 12-punch made the card a "loader".
