Data storage - old and new

We found an old 80-column punched card - a relic from the time my wife was a programmer on IBM 360 mainframes.

The data on this card is object code from an assembler, apparently.

That's a 1GB memory stick for comparison.


There's a more recently posted alternative picture here, along with a rant about data security:

and I have a shot of the punched card on its own if anyone needs one.

    What a fantastic photo! :)

    Seen in a tag search. (?)

    Thank you laserone!
    I hope 2008 is good to you (and Riley!)

    Gosh - it's hard to recall the days when computing involved punch cards -- it was all so slow back then.
  • cgt PRO 7y

    That picture represents the last 30 years of my professional life. Thanks for the memories ! The first mainframe I worked on had 128k - the storage cabinet was about the size of a large wardrobe.

    Thank you ivyknoll and cgt.

    I used it in thank you for cc-ying it.

    Hi pepperstory - thank you for letting me know about your use of this image, and thank you too for the correct acknowledgement.
  • Chris Champion PRO 6y

    This is a great photo. I'm using it to illustrate the word "deprecated" on the bulletin board in my computer science classroom. Thanks for licensing it CC.
  • Ian PRO 6y

    Thank you Chris. It's good to hear about how my picture is being used.
    From time to time I get misgivings about CC licensing, when someone pushes the boundaries too far, but comments like yours encourage me to stick with it.

    That's an excellent photo - I came across it embedded (with attribution of course, otherwise how did I get here? ;) in a django presentation on data migration.
  • Ian PRO 6y

    Thank you Tony, and it's good to know that the attribution rules are being followed.
    If you're involved with a data migration project, I hope it goes well. Problems with data quality sometimes start to loom large when it's migrated.

    Hi, I'm an admin for a group called Robots, Automatons, Mainframes and the Silicon Revolution, and we'd love to have this added to the group!

    I'm currently (and for the forseeable future) using this on my ICT & Computer Studies based resources site (where all resources are, naturally, released under a CC license) - Thanks for sharing!
  • Ian PRO 4y

    Mark Clarkson You're very welcome!
    (Some good stuff on Mike's site!)

    Awesome transposition... I used to punch baudot code holes into tape, that then ran through a tape transmitter, to send the signals to printers in other cities.., on the RR.

    Ah how I long for the good old days... Cause they were... :)
