The Acorn Electron is a budget version of the BBC Micro educational / home computer made by Acorn Computers Ltd.

At its peak, the Electron was the third best selling micro in the United Kingdom, and total lifetime game sales for the Electron exceeded those of the BBC Micro.

The Electron was developed during 1983 as a cheap sibling for the BBC Micro with the intention of capturing the low-cost Christmas sales market for that year.

Despite this, several features that would later be associated with BBC Master and Archimedes were first features of Electron expansion units, including ROM cartridge slots and the Advanced Disc Filing System — a hierarchical improvement to the BBC's original Disc Filing System.

This enabled the Electron to achieve the same functionality as that provided by the Expansion-ROM slot on the bottom-left of the BBC Micro B keyboard.

By providing extra storage this modification also allowed some games and applications intended for the BBC Micro to function on the Electron despite the lack of a native Mode 7.

Of the capabilities present in the BBC Micro but absent from the Electron, the teletext-style mode 7 was particularly conspicuous because of the very low memory usage in that mode ( just less than 1 kB ) and the high number of BBC programs that used it.

The Electron is widely misquoted as operating at 1. 79 MHz after measurements derived from speed testing against the thoroughly 2 MHz BBC Micro for various pieces of ' common software '

Like the BBC Micro, the Electron was constrained by limited memory resources.

Notable enterprises which produced discs of such software are BBC PD, Electron User Group and HeadFirst PD.

The Acorn Atom was a home computer made by Acorn Computers Ltd from 1980 to 1982 when it was replaced by the BBC Micro ( originally Proton ) and later the Acorn Electron.

Acorn Computers Ltd implemented a 1200 baud variation of CUTS in their BBC Micro and Acorn Electron microcomputers, which reduced a ' 0 ' bit to one cycle of a 1200 Hz sine wave and a ' 1 ' bit to two cycles of a 2400 Hz wave.

Elite is a seminal space trading video game, originally published by Acornsoft in 1984 for the BBC Micro and Acorn Electron computers.

Originally there were 3 versions of Elite released: Acorn Electron Tape, BBC B Tape and BBC B Disk.

Beginning with black and white adaptations of Nigel Kneale's BBC science fiction serials The Quatermass Experiment ( 1955 ) and Quatermass II ( 1957 ), Hammer quickly graduated to deceptively lavish colour versions of Frankenstein, Dracula and The Mummy.

BBC 7 repeated the original versions on 21 and 28 September 2003.

Later versions of the story have followed suit: the 1991 movie Robin Hood: Prince of Thieves and 2006 BBC TV series Robin Hood each contain equivalents of Nasir, in the figures of Azeem and Djaq respectively.

Star Trek: The Animated Series was the only Star Trek series not to feature a cold open (" teaser ") and started directly with the title sequence ( although some overseas versions of the original live action series, such as that run by the BBC in the U. K. in the 1960s and 1970s, ran the teaser after the credits ).

Television versions include the 1974 BBC TV movie, Alice Through the Looking Glass, with Sarah Sutton playing Alice, a 1982 38-minute Soviet cutout-animated film made by Kievnauchfilm studio and directed by Yefrem Pruzhanskiy, an animated TV movie in 1987, with Janet Waldo as the voice of Alice ( Mr. T was the voice of the Jabberwock ) and the 1998 Channel 4 TV movie, with Kate Beckinsale playing the role of Alice.

News and information is available on all these languages on the BBC Website with many having RSS feeds and specific versions for use on mobile phones and some also using email notification of stories.

Radio 4 Extra broadcast a variety of radio plays from the BBC ` s vast archives and a few extended versions of Radio 4 programs.

One of the most accessible versions was the 1978 television production by the BBC of the play, shown as part of " The Shakespeare Plays " ( a several years-long project to put all of Shakespeare's plays on tape ).

Radio 4's sister station, BBC Radio 4 Extra ( formerly known as BBC 7 ), complements the main channel by broadcasting repeats from the Radio 4 archive, extended versions of Radio 4 programmes and supplements to series such as The Archers and Desert Island Discs.

BBC Radio released audio-only versions of episodes starting in 1995.

Petula Clark released a recording of it in 1953 to coincide with the coronation of Queen Elizabeth II, and despite neither making the charts, both versions were popular on BBC radio's Children's Favourites programme.

BBC 7 repeated the original versions on 21 and 28 September 2003.

Emerick used the original equipment to record the new versions of the songs, and the results were broadcast on BBC Radio 2 on 2 June, marking the album's 40th anniversary.

On April 22, 2008, the BBC Radio 1 Rockshow broadcast a new session of Down recordings featuring alternate versions of " NOD ", " Beneath the Tides ", and " Jail ", along with a cover of " When The Levee Breaks " ( written by Kansas Joe McCoy and his wife Memphis Minnie, and famously covered by Led Zeppelin ).

Jailbreak and Johnny the Fox are double CD editions with the second disc containing outtakes, BBC session recordings and newly remixed versions of two of that particular album's tracks.

BBC documentation shows that " Sheila " and two versions of " Three Cool Cats " were recorded and never broadcast, but the tapes were likely reused or discarded, a fate shared by some of The Beatles ' studio session tapes prior to late 1963.

Although the station is essentially a rebranding of Radio 7, its content has been brought further in line with its sister station, BBC Radio 4, and new additions to its schedule include extended versions of established Radio 4 programmes such as The Now Show, The News Quiz and Desert Island Discs.

The channel simulcasts a network version of BBC One in High Definition, with HD versions of programmes including Holby City, The One Show, Strictly Come Dancing, The Apprentice, The Weakest Link and Doctor Who.

It also produces U. S. versions of some shows ( like What Not to Wear, originally a BBC production ) as well as original programming ( like Robotica ).

Once BAFTA judging had completed, the BBC re-launched the game in two distinct versions to showcase new artwork for scenes and objects deliberately omitted from the first release.

Acorn subsequently released alternative versions of the BBC disks that were compatible with the WD1770.

Neither the BBC nor the Electron tape versions featured missions.
