Circa 1964 Livermore Data Systems "Model A" Acoustic Coupler Modem, live demonstration.




Q&A: http://phreakmonkey.com/index.php/archives/134

Background: This modem was given to me ~1989 by the widow of a retired (IBM?) engineer. Computerhistory.org has a Model B dated 1965, and I've seen a ~1967 Model C written up in a magazine. (Interestingly, incorrectly identified as being only 110 baud.)

Even better than seeing it in a museum, I decide to hook the trusty Model A up and make it talk to something. After some trial and error, I manage to get it to talk to a terminal server at work and use it to connect to a linux box. It's ALIVE! So, 45 years after it's creation, this antique modem gets to send data to and from the modern Internet.




Enjoy!
- K.C.

  • so basically, if you were to take the phone off the modem, your connection would be dead and the whole thing is a phone call?

  • @notrodash I love that this is a revelation to someone. I forget that there's a whole generation of people who only know a world where all remote communications aren't through telephone lines.

  • You should black out the part of the video where you type the password. Not that I could make out what it was, but someone might be able to.

    Seriously, do this now.

  • @sg777778 Thanks. I'd hate for someone to go back in time to early 2009 and log into my lab workstation.

  • That is amazing! I'm not that familiar with the pinout of a serial port, but I guess RS-232 is a standard that never changed?

  • @sg777778 Well, that or change it.

  • Fucking love it! lol

  • this loads wikipedia faster than my broadband connection... :/
