The Interim Computer Museum (ICM) is a US-registered 501(c)(3) nonprofit dedicated to preserving and demonstrating the history of computing. Its exhibits pair original vintage hardware with modern enhancements, letting visitors interact directly with machines from earlier computing eras rather than just look at them behind glass.

ICM operates in partnership with SDF Public Access UNIX System, Inc., a separate 501(c)(7) membership organization at sdf.org. Membership dues support the museum's community events, remote access to its systems, and ongoing preservation of its hardware collection. The site lists sections for Events, Collections, Recollections, and a blog, alongside options to donate, join as a member, or arrange an in-person visit through its Visit page.

The museum's own FAQ addresses the obvious question, why it is still called "Interim," though the copyright footer already gives a clue: it has carried that name since at least 2020. The item reached the Hacker News front page with 105 points, proof that a museum can stay provisional for years and still draw a crowd.
