==== Sunday, November 22 2026 ====
all day starting 10:00 – #PDP-12 #hackathon
The PDP-12 is a laboratory computer introduced by #Digital Equipment Corporation (#DEC) in 1969. Only few dozen remain in existence today. Datorföreningen Update owns a PDP-12 called "Elsa", but it stopped working. You can read more about it in Update's newsletter Uptime 8 2023 (in Swedish).

In this hackathon, we will try to bring Elsa back to working condition. We will flip switches, read schematic diagrams, swap circuit boards, and observe signals. If this sounds intimidating, don't worry, we will learn from each other as we go. Everybody is welcome to participate, regardless of previous knowledge. Join us in this quest to bring Elsa back to live!
Drop in whenever you like. Food plans will be made spontaneously.
