  • jcrobso, please get in touch... I need help fixing my 5424!

  • Is this basically a computer, just a very early one? or does it serve a more specific purpose?

  • It's a middle-aged computer - late 60s / early 70s. Runs basic accounting/reporting type applications exclusively off punched cards; no interactive capability whatever. If you want to tell it to do something there's nothing resembling a command line: you have to punch the commands to run a program onto cards offline on a punch machine, then read the cards in...it talks back to you by displaying codes on the front LED and printing messages on the printer.

  • To be specific, this is a System 3 model 10. There were also System 3s models 6,8,12,15 and 15D. I was a hardware and software trained field service person on them from around 1972 till about 1980 when they were largely replaced for newer technology. The larger models did have a Console Monitor for commands and these could run up at 150 other terminals & devices.

    In that era they were the most numerous commercial computers in the world for small businesses.

  • System 3 was from the mid 1970s. It used a mini punched cards. It was a general purpose small main frame computer. I serviced them when I worked for IBM.

  • lol it has a big ressemblance of my heating system in my house^^

  • ciao! I'm Italian and my father was the inventor of ALU and CPU of IBM S/3 in 1967. I was born in 1968 in Rochester. Thank's...and buona fortuna!

  • "If I set the switch to option 3" (rotating the second-from-right rotary dial - middle of cabinet)

    "Hit start"

    "Its come up nine"

    "Hit start again"

    "It continues processing"

    "EJ, end of job" (pointing at letters EJ lower right display)

    "The IPL or boot process is now completed."
