Despite this all of the games released on ROM were packaged as 'serial ROMS', from which the micro would load programs into main memory in exactly the same way as if it were loading from tape. The analogue interface was normally used for joysticks, the parallel for a printer.ДЄccess to ROM memory occurred at 2 MHz regardless of graphics mode so theoretically programs released on ROM could run at least twice as fast as those released on tape or disc.

The Acorn Plus 1 added two ROM slots, an analogue interface and a parallel port.

This meant the Electron had a lifespan not much shorter than those more popular micros and much longer than competitors such as the Oric-1 and Dragon 32.

However, whilst it may not have been as popular as the Spectrum, Commodore 64, Amstrad CPC or even its own BBC sibling it did sell in sufficient numbers to ensure that new software was being produced right up until the early 1990s. The Electron is commonly thought of by many retro computer enthusiasts as a failure. 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. With hindsight, the machine was too lacking in RAM (a typical program would need to fit in only around 20 kB once display memory is subtracted) and processing power to take on the prevailing ZX Spectrum and Commodore 64.

Following Olivetti's 1985 cash injection into Acorn the machine was effectively sidelined. This was a blow from which the machine never fully recovered, although games sales for it would ultimately outstrip those of the BBC Micro. Although Acorn were able to shrink substantially the same functionality as the BBC into just one chip, manufacturing problems meant that very few machines were available for the Christmas period - to the extent that some shops reported eight presales for every delivered machine. 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. The ULA controlled memory access and was able to provide 32K Г— 8 bits of addressable RAM using 4 Г— 64K Г— 1-bit RAM chips (4164). The machine architecture also imposed a substantial speed decrease on applications running from RAM, although ROM applications ran at the same speed It had feature limitations such as being unable to output more than one channel of sound where the BBC was capable of three-way polyphony (plus one noise channel) and the inability to provide teletext mode. The hardware of the BBC Micro was emulated by a single customized ULA chip designed by Acorn.

There are at least 500 known games for the Electron and the true total is probably in the thousands Fact|date=January 2008. It was capable of basic graphics, and could display onto either a television set, a colour (RGB) monitor or a ' green screen' monitor.ДЄt 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 able to save and load programs onto audio cassette via a supplied converter cable that connected it to any standard tape recorder that had the correct sockets. It had 32 kilobytes of RAM, and its ROM included BBC BASIC along with its operating system. The Acorn Electron is a budget version of the BBC Micro educational/ home computer made by Acorn Computers Ltd.
