== Official == The only official clones of the Spectrum were made by [[Timex Sinclair|Timex]]. There were three models developed, only two of which were released: === Timex Sinclair 2068 === {{main|Timex Sinclair 2068}} 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.<ref name="byte198312">{{cite news |author=Advertisement |date=December 1983 |title=Now from Timex...a powerful new computer. |pages=281 |work=BYTE |url=https://archive.org/stream/byte-magazine-1983-12/1983_12_BYTE_08-12_Easy_Software#page/n281/mode/2up |accessdate=20 October 2013}}</ref> The most notable changes were the addition of a cartridge port, an [[AY-3-8912]] sound chip, and an improved [[Gate array|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 [[Komputer 2086|Unipolbrit Komputer 2086]] (UK 2086) respectively.<ref name="homecomputerde">[http://www.homecomputer.de/pages/easteurope_pl.html HCM: East-European Home-Computer], homecomputer.de website.

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.<ref>{{cite book |last1=Ferrándiz Javier |first1=José Ramón |title=Jurisprudencia sobre propiedad industrial, publicidad y derecho de la competencia |year=2007 |publisher=La Ley |isbn=9788497257954 |page=377}}</ref> 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 computer]]s. <gallery> File:Inves Spectrum+ (RetroMadrid 2018).jpg|Inves Spectrum + </gallery> ===Decibels dB Spectrum+=== The '''Decibels dB Spectrum+''' was an official clone of the [[ZX Spectrum#ZX Spectrum+|ZX Spectrum+]] for the Indian market, introduced in 1988 by Decibels Electronics Limited, selling over 50000 units and achieving an 80% market share.<ref>{{Cite web |title=Tirlochan Singh |url=https://isourcingindia.com/team/tirlochan-singh/ |access-date=2022-12-18 |website=isourcingindia |language=en-US}}</ref><ref>{{Cite web |title=Decibels Electronics Limited Information - Decibels Electronics Limited Company Profile, Decibels Electronics Limited News on The Economic Times |url=https://economictimes.indiatimes.com/company/ |access-date=2022-12-18 |website=The Economic Times |language=en}}</ref><ref>{{Cite web|url=https://www.sinclaircollection.site/?page_id=455|title=Decibels dB Spectrum+ – Sinclair Collection Site}}</ref><ref>{{Cite web |title=dB Spectrum+ at Spectrum Computing - Sinclair ZX Spectrum games, software and hardware |url=https://spectrumcomputing.co.uk/entry/1000517/Hardware/dB_Spectrum |access-date=2022-12-18 |website=Spectrum Computing |language=en}}</ref><ref>{{Cite web |title=The innovative legacy of Clive Sinclair |url=https://www.theweek.in/news/sci-tech/2021/09/18/the-innovative-legacy-of-clive-sinclair.html |access-date=2022-12-18 |website=The Week |language=en}}</ref> <gallery> File:DB_Spectrum%2B.jpg|Decibels dB Spectrum+ </gallery>
