	The next generation - The BBC Master series (1986) (Site not responding. Last check: 2007-11-06)
		The BBC Master 128 was released in January 1986, as a replacement for the highly successful BBC Micro range.
		The BBC Master was based on the 8-bit 65C02 processor, a later revision of the 6502A used in the earlier Acorn systems, and was provided with four times the memory, 128 Kb.
		The Master Compact (released in September 1986) was a standard BBC Master 128 fitted in to a three-box case along the same lines as the later Archimedes, with an integral 3.5" disc drive and lacking some of the interfaces (although an add-on was available which provided some of the missing interfaces).

	File Allocation Table - Wikipedia, the free encyclopedia
		With the usual hard disk sector size of 512 bytes, this gives 32 KB clusters, hence fixing the "definitive" limit for the FAT16 partition size at 2 gigabytes.
		DOS Plus on the BBC Master 512 did not use conventional boot sectors at all.
		Data disks omitted the boot sector and began with a single copy of the FAT (the first byte of the FAT was used to determine disk capacity) while boot disks began with a miniature ADFS filesystem containing the boot loader, followed by a single FAT.

	The BBC Master 512 - Using the XIOS
		The Master 512 is put together in quite a different way from a true IBM PC or 100% compatible machine, and so its "low level" software is also different.
		In this case BX must contain the segment value (in the 512) which is to be used for the screen memory.
		The memory maps in the 512 for these modes are very different, but since this function applies only to host screens the same screen type number is used for both of them.

	Wikidpedia - The free online encyclopedia - Acorn Computers Ltd
		Acorn's BBC Micro computer dominated the UK educational computer market during the 1980s and early 1990s, drawing many comparisons with Apple in the U.S. Though the company was broken up into several independent operations in 2000, it leaves an impressive legacy, particularly in the development of RISC personal computers.
		The BBC Micro, released by Acorn in 1982.
		BBC Education tested delivery of radio-on-demand programmes to primary schools, and a new educational service, Education Online, was established to deliver material such as Open University television programmes and educational software.

	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.
		The BBC B with 6502 second Procesor unit evolved into the Master Turbo, the BBC with Z80 second processor evolved into the Master 512, but with an 80186 as the main processor.
		The Masters also had to fight the threat of the steadily cheaper Atari ST. It was obvious that very few commercial applications took advantage of the extra features and power of the Masters.

		BBC Master Turbo and Master 512 - these were Master 128s with internal second processors and sold as a complete package.

	R.T.Russell: BBC BASIC for Windows
		In BBC BASIC text rows are counted from the top of the window and graphics coordinates are measured from the bottom of the window, so selecting a display mode with known dimensions is particularly important to ensure consistent alignment of text and graphics.
		As with the BBC Micro, the OSWORD function number is passed in A% and the address of the parameter block is passed in X% and Y%.
		BBC BASIC still uses a 'logical' palette of 16 colours, but this is purely for software convenience and to maximise compatibility between paletted and non-paletted displays.

		Although the BBC was a hideously expensive machine it was fast, had excellent sound, neat graphics and was the best home machine at shifting polygons this side of the Vectrex.
		During development (and before the BBC decided to choose the machine as its supported computer), the BBC was known as the Acorn Proton.
		The cases for the Acorn Atom and BBC Micro were designed by Allen Boothroyd who is also responsible for the sylish Meridian range of hi-fi equipment.

	OLD-COMPUTERS.COM : The Museum
		The BBC Master was an enhanced version of the BBC Model B providing improved features, but sadly also introducing compatibility problems with earlier BBC systems.
		The BBC Master and Master Compact could be considered the most accomplished 8-bit 'home' computers and among the last mass-produced 8-bit machines.
		While developing and marketing the BBC Master, Acorn realized the PC world was moving on from 8-bit to 16-bit processors and started developing their own 32-bit chip, the Acorn RISC Machine, or ARM.

		The Master 512 driver maps half of the colours to white, and one of them happens to be the blue used for the desktop pattern.
		Acorn also supplied a second fl and white driver that maps colours to fl like everything else, though according to Yellow Pig's BBC Computer Pages it had to be patched to work properly.

		It has also been implemented in portable C that can be compiled on almost any platform with a C compiler.
		BBC BASIC is not a BBC emulator, it is an implementation of the BBC BASIC programming language.

	Reading DFS and ADFS floppy disks under Linux
		I'm fortunate in that I still have a BBC Master 128 in service, but some of the data on the disks is useful to have on my day-to-day platform - which is Linux.
		BBC floppy disks number their sectors starting from 0, whereas it seems more common to number the sectors from 1.
		It would be great to get the BBC format disks added to this file, so one could use a construct like "setfdprm /dev/fd0 ADFS_L".

		All Acorns (including BBC), Apple Macintoshes (`Macs'), IBM and clones (`PCs'), and Research Machines computers (`RMs') are covered, and each item is marked to show the platforms on which it runs.
		The heavy early involvement of Acorn (BBC) computers in education, in multiple processors, and in fast RISC processors has given them a long lead over other platforms in the areas of cross-platform connectivity and easy file exchange.
		Systems such as PCs and Macs, which were designed for commercial purposes, have had a historic built-in resistance to connectivity and easy file exchange, as these were against their natural commercial interests in promoting their own particular systems and software.
