Very few computers had been released that far back. I don't know the details but he told me that they used a pickup truck to transfer the data (punch cards) from the Milwaukee to their main location in Madison, WI OK. If you don't know, no big deal; I was just curious. There is no way I'd remember what it was. He started with the company I worked for right after they got rid of the PDP-11 and got a Nixdorf . That was somewhere around 1980 He also said that he'd run a pencil across the stacks of cards and make a diagonal line in case someone dropped a stack...to facilitate re-ordering them. Yes, that was standard practice, not just with him and with Oscar Meyer, but with almost everybody using punched cards. And a magic marker was more common than a pencil. And by the way, that diagonal line didn't really facilitate reordering them; more than anything else it simply showed you whether the deck was still in sequence or needed fixing. If only a few cards were out of sequence that break in the diagonal might help you reorder them manually, but if the deck had been dropped, the way to reorder them was to run them through a card sorter. OK. |

Probably their daily production and possibly payroll records. (just guessing) Punched cards have existed for a long time :-) http://en.wikipedia.org/wiki/Jacquard_loom "Herman Hollerith took the idea of using punched cards to store information a step further when he created a punched card tabulating machine which was used in the 1890 U.S. Census." So even if they don't store a computer program, they can be used for "data analysis". Yes, as you say, they contained data well before they were used for computer programs. As I said earlier, I started programming on an IBM 1401 in 1962. Around the time I started, the company I worked for got its first computer. But they already had *tons* of punched cards. The cards were used to contain data that was processed by EAM machines (IBM 402, 407, etc.) I recall taking Fortran in college in the mid 1960's, and we only had limited access to one computer on campus - the University's IBM 1620 mainframe. By "limited access", I mean that you wrote your Fortran assignments on punch cards, turned it your assignment to the mainframe room, and, if you were lucky, you got it back *a week later* (since the administration stuff had precedence). But if you made a single programming error, it was tough nuggies for your grade on that assignment. Can you even imagine something like that today for our kids?? If they don't get their results back instantly, they're upset! :-) |

Wait in line to submit your cards. Wait several hours to get the printout. If you were missing as much as one unambiguous parentheses the program was spit out and not even run. Though we did not have to wait a week to get our program back... it did take a full week of constant work , waiting in line etc to actually get it working. Those dot matrix printers were fast though! |

You simply pressed it in place and it would usually be held in place by friction (at least for a while). But if you wanted a permanent fix, you would just punch a new card, or copy the card on a keypunch and fix the erroneous column. |

No one then could have predicted that in the future how trouble-free that was all to become. Florida would use voting machines completely free of any chad problems. G |

Yeah, except for the fact that the life was a bit simpler (but not necessarily easier) back then, and most folks had a greater sense of personal responsibility than now. |

Not actual glue; we used fingernail polish to glue the chad back in place. Other glue-like stuff we tried let the chad fall out, or jammed the reader. But if you wanted a permanent fix, you would just punch a new card, or copy the card on a keypunch and fix the erroneous column. Easy enough to punch a new non-binary card; nobody would bother with the chad-glue process except for binary cards. (ISTR that IBM 026 card punches would not copy some binary cards.) -- Cheers, Bob |

I'm wondering how it would be possible to put them back in order. How was that even done? Very carefully :-P When a card deck is dropped from a few feet, some bunches of the cards will stay together - and that helps a lot. Next, many of the cards had sequence numbers (columns 72-80?), and many had the instruction printed ("Hey, this pile looks like the disk driver"). Finally, after re-ordering the cards as much as possible, we re-assembled and started debugging. -- Cheers, Bob |

Next, many of the cards had sequence numbers (columns 72-80?), You're talking about a deck of program cards. Yes, they normally had sequence numbers (except when they were left out). But most decks of cards, and the biggest decks of cards, were normally data, not program cards. And data almost never had sequence numbers (nor did they normally need to be in any particular sequence). |
