Which Sinclair ZX Spectrum Model Was the Last Released?

This article identifies the final computer officially released under the Sinclair brand name within the ZX Spectrum lineage. It examines the transition of ownership from Sinclair Research to Amstrad and highlights the specific hardware that concluded the production of these iconic British home computers.

The Sinclair ZX Spectrum launched in 1982 and became one of the most successful home computers in history. Throughout its early life, Sinclair Research Ltd produced several iterations, including the original 16K and 48K models, the Spectrum+, and the Spectrum 128. These machines defined the British computing landscape during the 1980s and established a loyal user base that persisted for decades.

In April 1986, facing financial difficulties, Sinclair Research sold its computer business and the rights to the Sinclair brand name to Amstrad. While Sir Clive Sinclair remained involved with other projects, the future of the ZX Spectrum lay in the hands of Alan Sugar’s company. Amstrad continued to manufacture and sell machines under the Sinclair name, ensuring compatibility with the existing software library while updating the hardware design.

Following the acquisition, Amstrad released the Spectrum +2 in 1986, which featured a built-in cassette deck. However, the final major model to bear the Sinclair branding was the Sinclair ZX Spectrum +3. Released in 1987, the +3 distinguished itself by including a built-in 3-inch floppy disk drive instead of a cassette player, aiming to modernize the platform against competitors like the Commodore 64 and Amstrad CPC.

Although Amstrad later produced minor revisions known as the +2B and +3B to reduce manufacturing costs, the +3 remains recognized as the last significant model released under the Sinclair brand. Production of the ZX Spectrum line eventually ceased in 1992 when Amstrad discontinued the range to focus on their PC compatible systems. The ZX Spectrum +3 stands as the final chapter in the official history of Sinclair-branded computers.
