List of ZX Spectrum clones
The following is a list of clones of Sinclair Research's ZX Spectrum home computer. This list includes both official clones (from Timex Corporation) and many unofficial clones, most of which were produced in Eastern Bloc countries. The list does not include computers which require additional hardware or software to become ZX-compatible. Many software emulators can fully or partially emulate some clones as well.
The only official clones of the Spectrum were made by Timex. There were three models developed, only two of which were released:
The Timex Sinclair 2068 or T/S 2068 (also known as TC 2068 or UK 2086) was a significantly more sophisticated machine than the original Spectrum. The most notable changes were the addition of a cartridge port, an AY-3-8912 sound chip, and an improved ULA giving access to better graphics modes. The T/S 2068 was produced for consumers in the United States, while very similar machines were marketed in Portugal and Poland as the Timex Computer 2068 (TC 2068) and Unipolbrit Komputer 2086 (UK 2086) respectively. A small number of TC 2068s were also sold in Poland.
The Timex Computer 2048 or TC 2048 was a similar machine to the Spectrum 48K, but with the improved ULA from the TC 2068 (allowing access to the improved graphics modes), Kempston joystick port, and composite video output. Marketed only in Portugal and Poland.
The Timex Sinclair 2048 or T/S 2048 was a never-released variant of the T/S 2068 with 16 KB of RAM.
A clone of the ZX Spectrum+ developed by Investrónica in Spain in 1986, the Inves Spectrum + was based on the work developed by the company on the ZX Spectrum 128. Released just after Amstrad bought Sinclair Research Ltd, it looked much like a regular ZX Spectrum+, but all the internal components were redesigned. As the ROM was also modified, it has compatibility problems with some games – notably Bombjack, Commando, and Top Gun. A Kempston joystick port was fitted on the rear of the machine.
Due to Invéstronica being the distributor of Sinclair's products in Spain, and because Amstrad already had its own exclusive distributor in Spain (Indescomp, later bought by Amstrad itself), Amstrad sued Investrónica in 1987 to cease sales of the computer. The court agreed with Amstrad, but the decision was not issued until 1991, when the computer was discontinued, as the 8-bit computer market in Spain was succeeded by 16-bit computers.
The Decibels dB Spectrum+ was an official clone of the ZX Spectrum+ for the Indian market, introduced in 1988 by Decibels Electronics Limited, selling over 50000 units and achieving an 80% market share.
