1990

ZX Spectrum +3 production discontinued

In December 1990, Amstrad discontinued production of the ZX Spectrum +3, bringing the production run of its disk-based Spectrum to an end after just over three years. The +3 had been introduced in 1987 as the most advanced member of the Spectrum family, combining 128K of RAM with a built-in 3-inch floppy disk drive and support for CP/M.

The decision to discontinue the +3 was reportedly connected with Amstrad's relaunch of its own CPC range. The Spectrum +3 was effectively competing within Amstrad's own home-computer product line, while the simpler +2B was allowed to remain in production because it was considered less of a direct competitor to the CPC machines.

The end of +3 production did not immediately mean the end of the ZX Spectrum. Other Amstrad Spectrum models continued to be produced, with the +2B remaining available until 1992. Nevertheless, the discontinuation of the +3 marked the end of the final disk-based Spectrum model and the beginning of the final chapter of the Spectrum's commercial life.
