The museum's DMS-10 was acquired in 2023. This particular model was manufactured in around 2001 and contains contemporary computer components such as a PowerPC CPU, 3.5-inch hard drives, and 128 MB of RAM.

History

The DMS-10 was originally installed around the year 2001 in Sherman, Texas by the Grayson-Collin Electrical Co-Op (GCEC). After GCEC moved to VoIP based services, the switch was sold to ADTRAN, for use in their corporate lab in Huntsville, AL.

The machine served ADTRAN's lab for several years as a test unit, but was eventually decommissioned again when the company no longer had any use for it. After shutdown, it stayed in their lab for several more years. Eventually, an individual who was a fan of the museum's YouTube channel advised an ADTRAN employee that perhaps the museum could use the machine.

In 2023, ADTRAN reached out to the museum to inquire if we wanted the switch. After enthusiastically accepting their offer, volunteers Sarah, Matt Mullins, and Cody Harris flew down to Alabama to retrieve the switch and drive it back to Seattle in a Penske truck.

Museum Life

The switch was craned into the museum in the Summer of 2023, and installed on the second floor behind the 3ESS. Volunteer Colin Slater wired up the switch, and it was first powered on at the museum on January 21, 2024. The machine is administrated by Matt Mullins and Colin Slater.
