On the net with a 1964 acoustic modem…

On the net with a 1964 acoustic 300 baud modem…

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.

As modern ISPs freak out about our data usage they’ll likely start issuing these to all of us.



Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. Beautiful hardware, fun video.

  3. Nice. As a child, I narrowly avoided buying an Atari 830 acoustic modem, opting for the Atari 835.. cutting-edge “direct connect” (no acoustic cups and 300 baud!)… awesome for 1984!

    No Internets back then, but you could surf the world of BBS’s and Compuserve, Delphi, Games People Play (which I think became AOL), etc. Said surfing could be done for free if you ran a little program overnight.

    Ah, now I am nostalgic for the old 8-bit systems, and interfacing common Arduino shields to them. 🙂
