After the Atom had been released into the market, Acorn contemplated building modern [[16-bit computing|16-bit]] processors to replace the Atom. After a great deal of discussion, Hauser suggested a compromise—an improved 6502-based machine with far greater expansion capabilities: the Proton. Acorn's technical staff had not wanted to do the Atom and they now saw the Proton as their opportunity to "do it right".{{citation needed|date=September 2021|reason=Source was an "email from Sophie Wilson", which is not [[WP:RS|reliable or verifiable]]}}

One of the developments proposed for the Proton was the ''Tube'', a proprietary interface allowing a second processor to be added. This compromise would make for an affordable 6502 machine for the mass market which could be expanded with more sophisticated and expensive processors. The Tube enabled processing to be farmed out to the second processor leaving the 6502 to perform data [[input/output]] (I/O). The Tube would later be instrumental in the development of Acorn's [[ARM architecture family#History|ARM processor]].<ref>{{cite magazine |quote=Should Acorn abandon the 6502 processor which lay at the heart of all its machines?

In early 1980, the [[BBC]] Further Education department conceived the idea of a computer literacy programme, mostly as a follow-up to an [[ITV (TV network)|ITV]] [[documentary film|documentary]], ''The Mighty Micro'', in which [[Christopher Evans (computer scientist)|Dr Christopher Evans]] from the UK [[National Physical Laboratory (United Kingdom)|National Physical Laboratory]] predicted the coming [[microcomputer revolution]].<ref>{{Cite web|url=http://www.offthetelly.co.uk/?page_id=568|archive-url=https://web.archive.org/web/20111128100448/http://www.offthetelly.co.uk/?page_id=568|url-status=dead|website=Off the Telly |title=Standby for a Data-Blast |first=Jack |last=Kibble-White |date=December 2005|archive-date=28 November 2011}}</ref> It was a very influential documentary—so much so that questions were asked in [[Parliament of the United Kingdom|Parliament]]. As a result of these questions, the [[Department of Industry]] (DoI) became interested in the programme, as did [[BBC Enterprises]], which saw an opportunity to sell a machine to go with the series. BBC Engineering was instructed to draw up an objective specification for a computer to accompany the series.

Eventually, under some pressure from the DoI to choose a British system, the BBC chose the [[Grundy NewBrain|NewBrain]] from Newbury Laboratories. This selection revealed the extent of the pressure brought to bear on the supposedly independent BBC's computer literacy project—Newbury was owned by the [[National Enterprise Board]], a government agency operating in close collaboration with the DoI. The choice was also somewhat ironic given that the NewBrain started life as a Sinclair Radionics project, and it was Sinclair's preference for developing it over Science of Cambridge's MK14 that led to Curry leaving SoC to found CPU with Hauser.{{Citation needed|date=August 2009}} The NEB moved the NewBrain to Newbury after Sinclair left Radionics and went to SoC.

In 1980–1982, the British [[Department for Education and Skills (United Kingdom)|Department of Education and Science]] (DES) had begun the [[Microelectronics Education Programme]] to introduce microprocessing concepts and educational materials. In 1981, through to 1986, the DoI allocated funding to assist UK local education authorities to supply their schools with a range of computers, the {{nowrap|BBC Micro}} being one of the most popular. Schools were offered 50% of the cost of computers, providing they chose one of three models: BBC Micro, {{nowrap|ZX Spectrum}} or [[Research Machines 380Z]].<ref>{{cite news | first = Nick | last = Langley | title = Schools: the early learning curve | date = 1989-09-09 | work = [[New Scientist]] | pages = 65 | quote = In 1981 the British government launched a scheme which offered schools 50% of the cost of a computer from one of three suppliers. The computers were the Sinclair Spectrum, the BBC Micro from Acorn and the Research Machines 380Z, all 8-bit machines.}}</ref> In parallel, the DES continued to fund more materials for the computers, such as software and applied computing projects, plus teacher training.

Although the NewBrain was under heavy development by Newbury, it soon became clear that they were not going to be able to produce it—certainly not in time for the literacy programme nor to the BBC's specification. The BBC's programmes, initially scheduled for autumn 1981, were moved back to spring 1982. After Curry and Sinclair found out about the BBC's plans, the BBC allowed other manufacturers to submit their proposals. Hauser quickly drafted in [[Steve Furber]] (who had been working for Acorn on a voluntary basis since the ACE fruit machine project) and [[Sophie Wilson]] to help complete a revised version of the Proton which met the BBC's specifications. BBC visited Acorn and were given a demonstration of the Proton. Shortly afterwards, the literacy programme computer contract was awarded to Acorn, and the Proton was launched in December 1981 as the [[BBC Micro]]. In April 1984, Acorn won the [[Queen's Award for Technology]] for the BBC Micro. The award paid special tribute to the BBC Micro's advanced design, and it commended Acorn "for the development of a microcomputer system with many innovative features".

In April 1982, Sinclair launched the [[ZX Spectrum]]. Curry conceived of the [[Acorn Electron|Electron]] as Acorn's sub-£200 competitor. In many ways a cut-down BBC Micro, it used one Acorn-designed [[Gate array|uncommitted logic array]] (ULA) to reproduce most of the functionality. But problems in producing the ULAs led to short supply, and the Electron, although launched in August 1983, was not on the market in sufficient numbers to capitalise on the 1983 Christmas sales period. Acorn resolved to avoid this problem in 1984 and negotiated new production contracts. Acorn became more known for its {{nowrap|BBC Micro}} {{nowrap|model B}} than for its other products.<ref>{{cite news|last=Sadauskas|first=Andrew|title=BBC Micro B lives on: Strong growth for ARM after increased tablet and smartphone use|url=http://www.smartcompany.com.au/information-technology/050914-bbc-micro-b-lives-on-strong-growth-for-arm-after-increased-tablet-and-smartphone-use.html|access-date=7 August 2012|newspaper=SmartCompany|date=27 July 2012|url-status=dead|archive-url=https://web.archive.org/web/20120728230947/http://www.smartcompany.com.au/information-technology/050914-bbc-micro-b-lives-on-strong-growth-for-arm-after-increased-tablet-and-smartphone-use.html|archive-date=28 July 2012}}</ref>

In 2008, the [[Computer Conservation Society]] organised an event at London's [[Science Museum, London|Science Museum]] to mark the legacy of the BBC Micro. A number of the BBC Micro's principal creators were present, and Sophie Wilson recounted to the BBC how Hermann Hauser tricked her and Steve Furber to agree to create the physical prototype in less than five days.<ref>{{cite news|title=BBC Micro ignites memories of revolution|url=http://news.bbc.co.uk/1/hi/technology/7307636.stm|work=[[BBC News]]|date=2008-03-21|access-date=2011-06-29|url-status = live|archive-url=https://web.archive.org/web/20080407140141/http://news.bbc.co.uk/1/hi/technology/7307636.stm|archive-date=7 April 2008}}</ref> Also in 2008 a number of former staff organised a reunion event to mark the 30th anniversary of the company's formation.<ref>{{cite web | url = http://www.drobe.co.uk/riscos/artifact2200.html | title = Acorn celebs to mark 30th anniversary with reunion | access-date = 2011-07-21 | date = 2008-01-28 | website = [[Drobe]] | quote = Top Acorn Computers luminaries are planning a reunion for former company staff to mark the firm's 30th birthday, drobe.co.uk has learned. | url-status = dead | archive-url = https://web.archive.org/web/20120210072848/http://www.drobe.co.uk/riscos/artifact2200.html | archive-date = 10 February 2012}}</ref><ref>{{cite web | url = http://www.reghardware.com/2008/08/28/acorn_30_reunion/ | title = Acorn alumni to toast tech pioneer's 30th anniversary | access-date = 2011-07-21 | last = Smith | first = Tony | date = 2008-08-28 | work = RegHardware, [[The Register]] | quote = Some 400 staffers from that flag bearer of the 1980s UK home computing revolution, Acorn, are to gather next month to celebrate the 30th anniversary of the firm's foundation. | url-status = dead | archive-url = https://web.archive.org/web/20110525053906/http://www.reghardware.com/2008/08/28/acorn_30_reunion/ | archive-date = 25 May 2011}}</ref><ref>{{cite news | url = http://www.zdnet.co.uk/news/desktop-hardware/2008/08/29/acorn-to-celebrate-30th-anniversary-39472541/ | title = Acorn to celebrate 30th anniversary | access-date = 2011-07-21 | last1 = Goodwins | first1 = Rupert | last2 = Barker | first2 = Colin | date = 2008-08-29 | work = [[ZDNet]] | quote = Thirteenth of September will see the 30th anniversary of UK technology company Acorn Computers, famous in the 1980s 8-bit boom for its 6502-based microcomputers such as the Electron, Atom and BBC Micro.
