The May 2026 Obsolescence Guaranteed newsletter highlights significant progress in recreating historical computing environments, most notably through the Arpanet Reconstruction project which now features a functional 35-node simulated network. Major software and hardware updates have arrived for the PiDP series, including new operating systems like Stanford's WAITS for the PiDP-10 and Unix v4 for the PiDP-11. The community continues to expand with enhanced peripheral support for the PiDP-1, new interactive museum concepts, and a growing library of "paleogaming" classics.
* Arpanet Reconstruction: A simulated 35-node network is now online, allowing users to experience the original topology via MIT and Stanford systems.
* PiDP-10 Update: The addition of Stanford's WAITS operating system brings 600MB of historical data and software for exploration.
* PiDP-1 Advancements: New community mods have introduced magnetic drum storage, light pen support, and a wide array of peripheral options.
* PiDP-11 Milestones: Unix v4 has been successfully recovered and is now bootable on the PiDP-11 platform.
* Enigma Touch: A new cased version featuring high-quality woodworking and historically accurate leather straps and metal clips is available.
