Editing List of ZX Spectrum clones (section)

=== Inves Spectrum + ===
A clone of the ZX Spectrum+ developed by Investrónica in Spain in 1986,<ref>{{Cite web|url=https://www.sinclaircollection.site/?page_id=453|title=Inves Spectrum+ – Sinclair Collection Site}}</ref> the '''Inves Spectrum +''' was based on the work developed by the company on the [[ZX Spectrum 128]].<ref name="Bourne">{{Cite journal |last=Bourne |first=Chris |date=November 1985 |title=News: Launch of the Spectrum 128 in Spain |url=http://www.sincuser.f9.co.uk/044/news.htm |url-status=dead |journal=[[Sinclair User]] |issue=44 |page=5 |archive-url=https://web.archive.org/web/20060924095443/http://www.sincuser.f9.co.uk/044/news.htm |archive-date=24 September 2006 |access-date=15 August 2006}}</ref> Released just after [[Amstrad]] bought [[Sinclair Research Ltd]], it looked much like a regular [[ZX Spectrum#ZX Spectrum+|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 (video game)|Top Gun]].<ref>{{cite book |last1=del Vas |first1=Jesús Martínez |title=Queremos su Dinero: EL Hombre tras Amstrad España |year=2019 |publisher=Dolmen Books |isbn=9788417956288 |page=124}}</ref> 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.<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.
