  BBC Micro - Wikipedia, the free encyclopedia
The project was initiated largely in response to an extremely influential BBC documentary The Mighty Micro, in which Dr. Christopher Evans from the National Physical Laboratory predicted the coming (micro)computer revolution and its impact on the economy, industry and lifestyle of the United Kingdom.
The BBC discussed the issue with Sir Clive Sinclair, who tried to offer the unsuccessful Grundy NewBrain micro to them, but it came nowhere near the specification the BBC had drawn up, and was rejected.
The BBC Micro provided in-game graphics for the BBC TV show "The Adventure Game", where the BREAK key on the keyboard was covered by a plastic box to prevent accidental pressing.

 The BBC lives! -- Introduction & History
The BBC had serious discussions with Clive Sinclair (or Sir Clive), who tried to peddle the terrible "NewBrain" micro to them, but it came nowhere near the specification the BBC had drawn up, and was rejected.
BBC Education made several series "starring" the BBC Micro, which included: "The Computer Programme", "Making the Most of The Micro", "Computers In Control" (about robots and other hardware), "Micro Live" (weekly computer news magazine), and it also made the ground-breaking "Domesday Project" in 1986.
BBC Radio 4 had a programme called "The Chip Shop" which broadcast some software for the BBC Micro that could be taped and then loaded.

 BBC Micro and Electron Games - The Stairway To Hell - History
The BBC required a home computer to complement their upcoming television series and, as nothing on the market at the time was deemed to be suitable, they issued a specification list to which the new micro must conform and invited proposals from the leading manufacturers.
The BBC Micro was originally available in two flavours: the 16k Model A (£235, later increased to £299) and the 32k Model B (£335, later increased to £399).
Perhaps its most notable accomplishment was ousting the BBC Micro from third spot in the hardware charts, whilst the Commodore 64 and 48k Spectrum lead the field.

 BBC B Micro review. Electronics & Computing Monthly December 1982
If you are aware of the early history of the BBC Micro project you may know that the 6502 was specifically ruled out in the early specifications for the machine, which stipulated a Z80 CPU.
The BBC Micro (Model B) is not just another all-singing, all-dancing home computer, it is the basis of a really powerful system and one that will last into an exciting future.
The BBC Micro has a standard 7-pin DIN audio socket and the User Guide advises you to obtain a lead with "suitable plugs for your particular recorder" at one end and either a 7-pin DIN or a 5-pin DIN at the other.

 The BBC Computer Literacy Project - The BBC Micro (1981)
To enable the BBC Micro to be so fast, a large amount of the computer circuity was bundled up in to two Uncommitted Logic Arrays (ULAs), of which 10,000 were ordered from Ferranti.
Initially two versions of the BBC Micro were launched, known as the Model A and the Model B. Both were based around a 2 MHz 6502 processor and featured the same operating system and language, BBC BASIC I (later BBC BASIC II), housed in 32 Kb of ROM.
The original BBC Micro cost £235 or £335 (for the Model A and Model B, respectively), but this was later increased to £299 and £399.

The BBC Micro has composite video output which is easily connected to a modern TV.
Connecting the BBC to the SCART socket of a TV requires that the signal levels be reduced from 5V down to 0.7V.
Eventually the level shifter circuitry could be housed inside the BBC micro, in which case the connections are indeed short.

BBC floppy diskettes use "single density" compared to "modern" diskettes used on PCs (which are "double" and "high" density).
BBC Explorer is a drag-and-drop Windows program that can create a new disk image from dragged BBC files or their *.inf files, or extract such files from an exisiting image.
Downloading on the BBC means loading a file into a certain range of memory, then moving it to another range, usually lower in memory.

A MAJOR breakthrough that could save BBC Television thousands of pounds in equipment costs has been made by BBC TV networks engineer Tim Kennington using a BBC Micro.
Kennington, 31, has written a program that enables the BBC Micro to be used as a terminal to create pages on the Ceefax service.
If current tests with the program are successful BBC TV outside broadcast teams will use micros to transmit Ceefax pages direct from live events.

 My first computer: The BBC Micro - Desktops - Breaking Business and Technology News at silicon.com
The BBC Micro was first conceived of as a response to the wide public interest aroused by BBC documentary The Mighty Micro about the impending computer revolution.
In 1981, the BBC Micro models A and B were released and quickly became the basic (perhaps I should say BASIC) fare of schoolchildren up and down the land.
The BBC B was followed up - somewhat belatedly - in 1985 by the BBC B+ and eventually the BBC Master, which both added extra graphics and extra memory.

 New BBC Micro Adventure Games - About
Commissioned by the BBC and built by Acorn Computers, the humble BBC Micro came out in 1981 and, thanks to government funding, soon ended up in virtually every school in the UK during the first half of the 80's.
The BBC was capable of so much more, and a lot of the games had something appealing about them; the programmers seemed more willing to try something new rather than just copy the latest arcade games.
My original BBC finally packed up a few year back, which was very sad - until I found that you can get several BBC Emulators to run on a PC.

 BBC Micro Disk Controllers
When the BBC Micro models A and B were first released, it was possible to add a disk upgrade to the machine, Mind you, the upgrade cost about £120, so it wasn't a popular upgrade initially - until people got hacked off with a large program taking 20 minutes to load from cassette tape.
In Acorn's design of the BBC Micro, the floppy disk controller appears in the memory map from andFE80 - andFE9F - however only 3 address lines are made available to the floppy disk controller, and so only 8 locations are uniquely addressable (e.g.
This was a daughter board which plugged in to the 8271 socket on the BBC motherboard, but this time the daughter board carried a Western Digital 1770 disk controller AND a socket for the displaced 8271 disk controller.

 BBC in MESS page
The extra 64K of ram in the BBC B+ 128K was just mapped in as 4 banks of sideways ram in bank 0,1,C and D. I guess I should really add some sideways ram to the BBC B driver at some point soon.
I have made up a detailed report of where exactly the BBC driver for MESS is at, look at the picture at the bottom of this page to understand the colour information.
I think I am going to have to write a program that turns BBC files back into cassette wave files, it is all a little bit mad but I am having lots of fun getting this one working, I will keep you posted on how it is coming along.

Because of its BBC-approved status, the Acorn BBC Micro was the computer of choice for British schools and loads of kids brought up in the UK during the 80s would have encountered a BBC Micro at some point.
The BBC came in a variety of guises including the A, B, B+ and Master series.
Acorn eventually abandoned the BBC to develop its own next generation machine in the late 80s, the advanced-for-its-time 32-bit Archimedes series.

 John Allen's Z88 Link for BBC Micro
As there are no plans for a 'BBC Link II', an easy to use file transfer link between the BBC micro and a Z88, we've done our own, the result is the listing opposite.
The other options on the main menu allow you to show a list of BBC files in the current directory and transfer then to the Z88 (the procedure is similar to sending files from the Z88 to the BBC micro), and to enter '*' commands, for example to change the current drive or directory.
The problem is that bytes in the range &10-&1F on the Z88 were transferred to the BBC micro as bytes in the range &20-&2F so if you sent the file back to the Z88 it's not the same as when it went.

 The BBC lives! -- Emulators
According to Tom Seddon, this emulator is rather useless due to a number of bugs, and overall slowness (pure C implementation).
BBC BASIC(Z80) can be downloaded free of charge.
Because this is not a full BBC micro emulation, but rather an adaption of the BBC BASIC language for other platforms, the performance is much higher than full-fledged emulators when it comes to BASIC power.
