History
The museum's origins date to 1981 when a Baltimore ComputerLand franchise had computers in inventory that instantly became historic artifacts with the introduction of the IBM Personal Computer.

The museum was incorporated as a non-profit 501(c)(3) in 2018 as the Maryland Technology Museum with the trade name the System Source Computer Museum. In 2021, the museum became the new home of the DigiBarn Computer Museum.
