Editing Amstrad CPC (section)

==Influence on other Amstrad machines==
Amstrad followed their success with the CPC 464 by launching the [[Amstrad PCW]] word-processor range, another Z80-based machine with a 3" disk drive and software by [[Locomotive Software]]. The PCW was originally developed to be partly compatible with an improved version of the CPC (''ANT'', or Arnold Number Two - the CPC's development codename was Arnold).<ref>{{Cite web |url=https://www.theregister.co.uk/2014/02/12/archaeologic_amstrad_cpc_464/ |title=You're NOT fired: The story of Amstrad's amazing CPC 464 |last=Smith |first=Tony  |date=12 February 2014 |website=www.theregister.co.uk |language=en |access-date=2018-12-20}}</ref><ref>{{Cite news |url=https://www.pressreader.com/uk/retro-gamer/20171228/284185106163072 |title=The CPC that never was |date=28 December 2017 |work=[[Retro Gamer]]}}</ref> However, Amstrad decided to focus on the PCW, and the ANT project never came to market.

On 7 April 1986, Amstrad announced it had bought from [[Sinclair Research]] "...the worldwide rights to sell and manufacture all existing and future Sinclair computers and computer products, together with the Sinclair brand name and those intellectual property rights where they relate to computers and computer-related products."<ref>{{Cite web|url=https://www.crashonline.org.uk/28/news.htm|title=CRASH 28 - News|website=www.crashonline.org.uk}}</ref> which included the [[ZX Spectrum]], for £5 million. This included Sinclair's unsold stock of [[Sinclair QL]]s and Spectrums. Amstrad made more than £5 million on selling these surplus machines alone. Amstrad launched two new variants of the Spectrum: the [[ZX Spectrum +2]], based on the ZX Spectrum 128, with a built-in [[compact audio cassette|tape]] drive (like the CPC 464) and, the following year, the [[ZX Spectrum +3]], with a built-in [[floppy disk]] drive (similar to the CPC 664 and 6128), taking the 3" discs that Amstrad CPC machines used.
