The Timex/Sinclair community was enthusiastic and eager to explore the features and inner workings of the Timex/Sinclair 2068 as promised in the user’s guide and the technical manual. Unfortunately, when Timex Computer Corporation exited the market, the only resources for machine language programming were for the ZX Spectrum. A number of users stepped in to fill the knowledge gap, learning from the two main documents and each other, they wrote dozens of articles for newsletters about the many unique aspects of the Timex/Sinclair 2068 computer. This volume collects the best of their works.
