Timex Sinclair Online User Group

Founded: 2020

This informal group has twice a month meetings online (via Zoom). Like in-person user group meetings, we have guests, talk about our projects and a wide array of computing topics.

This group has its origins in the Yahoo TS 2068 Group, which migrated to groups.io when Yahoo Groups shut down.
