Community Projects

A curated tracker of the hardware builds, software tools, reference knowledge, and preservation efforts the Timex/Sinclair community has produced — a starting point for newcomers and a lasting reference for everyone. Each entry links to the discussions behind it (and, soon, the meetings where much of the work is reported).
