===Development=== In order to reduce component costs, and to prevent cloning, the company reduced the number of chips in the Electron from the 102 on the BBC Micro's motherboard to "something like 12 to 14 chips"<ref name="smith20130823">{{cite web |url=https://www.theregister.co.uk/2013/08/23/acorn_electron_history_at_30/ |title=Acorn's would-be ZX Spectrum killer, the Electron, is 30 |publisher=The Register |work=2013-08-23 |access-date=12 January 2015 |last1=Smith |first1=Tony }}</ref>{{rp|page=1|quote=Central to cutting the cost of the new machine was reducing the chip count. In place of the BBC’s various ancillary logic chips, the Electron would employ a single Uncommitted Logic Array (ULA) chip, a trick Sinclair had employed in the ZX81 and Spectrum; the ZX80 had used off-the-shelf TTL parts. “That allowed us to take a machine which had 102 chips on the motherboard and reduce it to something like 12 or 14 chips,” says Furber, “basically an order of magnitude reduction in the complexity of the motherboard.”}} with most functionality on a single 2,400-gate [[Uncommitted Logic Array]] (ULA).<ref name="popcompweekly19830901" /> The operating system ROM locations 0xFC00-0xFFFF contain the details of some members of the Electron's design team, these differing somewhat from those listed in the corresponding message in the [[BBC Micro|BBC Model B]] ROM:<ref name="acornuser198309_credits">{{ cite magazine | url=https://archive.org/details/AcornUser014-Sep83/page/n30/mode/1up | title=The Elk's 'MOS' Roll Call | magazine=Acorn User | date=September 1983 | access-date=19 October 2022 | pages=29 }}</ref> {{boxquote|(C) 1983 Acorn Computers Ltd.
