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.

Sign up for a email list. We’re usually on topic and there are lots of other smart and fun folks. Even though it’s named for the 2068, we cover all the Timex/Sinclair computers and even the QL and Z88.

Join Our Zoom Meetings

We meet on the 1st Monday and 3rd Sunday of the month (unless it’s a holiday).
