An old acoustic modem from 1964 still works after 46 years, as is shown in this video. Notice the beautiful wooden box it comes in. The author of the video says: “This circa 1964 Livermore Data Systems “Model A” Acoustic Coupler Modem was given to me about 1989 by the widow of a retired (IBM?) engineer. Computerhistory.org has a Model B dated 1965, and I’ve seen a ca. 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 managed 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.”
