In those days, the cardstock was extremely available, in large sheets and in precut blanks, in a variety of colors. Print-shops abounded who would do custom cards, if your business thought that it needed them. And yet, some card readers were amazingly tolerant! For example, half a century ago, CBS had a bunch of projects, such as the National Driver's Test (1966). IBM provided the hardware and software. They decided to give out Port-A-Punch cards, which were 80 column cards with every other column of holes pre-perforated, so that anybody could take a special stylus or a random pencil and create their own hanging chips/"Chads". But, how to recollect them? They actually had people stick a stamp on them and MAIL them! ("Business Reply Mail" would have shifted the franking burden, otherwise it would have made MUCH more sense) They then successfully ran them through the card reader of a 360! Keep in mind that it was an IBM PR stunt, so they had a CE standing next to the reader, clearing jams in real-time. I wonder if IBM cheated and modified the input maw? So, the specific card-stock is critical, but it worked with a postage stamp stuck to it? Although the hardware reliability was a welcome surprise (I wonder how my life would have gone if it hadn't), the software wasn't. The live statistics weren't adding up close enough to 100%! On camera, Walter Cronkite was stalling, and right behind him, my father was frantically manually adding the numbers. Starting a week later, there were a copy of McCracken FORTRAN and Decima Anderson's book on my parent's coffee table. Instead of continuing to use 084 sorters, we learned a little FORTRAN. -- Grumpy Ol' Fred cisin at xenosoft.com
