While nine models were eventually produced with the BBC brand, the phrase "BBC Micro" is usually used colloquially to refer to the first six (Model A, B, B+64, B+128, Master 128, and Master Compact), excluding the During the early 1980s, the BBC started what became known as the The Acorn team had already been working on a successor to their existing Additionally, the last bytes of the BASIC ROM (v2 and v4) include the word "Roger", thought to be a referenceThe machine was released as the BBC Microcomputer on 1 December 1981, although production problems pushed delivery of the majority of the initial run into 1982.Efforts were made to market the machine in the United States and West Germany.The cost of the BBC Models was high compared to competitors such as the ZX Spectrum and the Commodore 64, and from 1983 on Acorn attempted to counter this by producing a simplified but largely compatible version intended for game playing, the 32K A key feature of the BBC Micro's design is the high-performance RAM it is equipped with.

The extra RAM in the The B+ is incapable of operating some original BBC B programs and games, such as the very popular There is also a long-running problem late in the B/B+'s commercial life infamous amongst B+ owners, when Superior Software released The BBC Micro platform amassed a large software base of both games and educational programs for its two main uses as a home and educational computer. Watch Queue Queue The cut-out space next to the keyboard (nicknamed the "ashtray") was more commonly used to install other upgrades, such as a ZIF socket for conventional paged ROMs. The 1985 'BBC Microcomputer Service Manual' from Acorn documents the details of the technical changes. Please quote this reference ID in any communication with the Centre for Computing History. All orders are custom made and most ship worldwide within 24 hours. If problems occur with this sort of machine, the problem can generally be cured by the use of either a Rockwell 6502A CPU chip, or by replacing IC14 (a 74LS245) with either another 74LS245 or the faster 74ALS245.US models include the BASIC III ROM chip, modified to accept the American spelling of Acorn introduced the Model B+ in mid-1985, increasing the total RAM to 64 KB but this had modest market effect. And who remembers using LOGO to command the turtle on the floor on a big sheet in the classroom to draw shapes. Logo's most-known feature is the turtle (derived originally from As a practical matter, the use of turtle geometry instead of a more traditional model mimics the actual movement logic of the turtle robot. The BBC Micro was used extensively to provide graphics and sound effects for many early 1980s BBC TV shows. Watch Queue Queue. The original plan was that some games would be released on cartridges, but due to the limited sales of the speech upgrade, little or no software was ever produced for these sockets. During the early 1980s, the BBC started what became known as the BBC Computer Literacy Project.The project was initiated partly in response to an ITV documentary series The Mighty Micro, in which Christopher Evans of the UK's National Physical Laboratory predicted the coming microcomputer revolution and its effect on the economy, industry, and lifestyle of the United Kingdom. This was held at There are also a number of websites still supporting both hardware and software development for the BBC micros and Acorn in general.The BBC B+ and the later Master provided 'shadow modes', where the 1–20 KB frame buffer was stored in an alternative RAM bank, freeing the main memory for user programs. Il BBC Micro (anche British Broadcasting Corporation Microcomputer System) era un home computer progettato e costruito da Acorn Computers per la British Broadcasting Corporation (BBC) tra il 1981 ed il 1994.. Nei primi anni ottanta, la BBC creò quello che divenne noto come il BBC Computer Literacy Project (progetto BBC per l'alfabetizzazione informatica).

Notable examples of each include the original release of Although appropriate content was little-supported by television broadcasters, BASIC, other languages, and utility ROM chips reside in any of four 16 KB Not all ROMs offer star commands (ROMs containing data files, for instance), but any ROM can "Acorn strongly discouraged programmers from directly accessing the system variables and hardware, favouring official As the early BBC Micros has ample I/O allowing machines to be interconnected, and many schools and universities employed the machines in In line with its ethos of expandability Acorn produced its own range of peripherals for the BBC Micro, including:
