ID Acorn BBC Master
Short Name
Name BBC Master
Company Acorn
Description In 1986 the Acorn Business Computer range was long gone, and Olivetti -
Acorn's new owners, having been forced to increase their stake from 49
to 80 per cent of the firm - were concentrating on making Acorn more
profitable. The case for the 65C816-based Communicator was retained and
given a basic box, housing a PSU and disk drive, to make a standard-looking 3-box computer system based around the BBC Master architecture.
Also marketed in Europe as the Olivetti Prodest PC 128 S (S for Sistema), the Master compact differed from other computers in a number of annoying ways. Most confusing was the decision to keep the computer in the keyboard, with suitable reductions in available interfaces and features such as the real-time clock - making the Master Compact rather like a grown up Electron (however, home marketing would unfortunately not be attempted - it would have been considerably more successful). The 'CPU' was connected via a large ribbon cable and a jack plug. The monitor connected to the 'keyboard'. It was, to be blunt, a mess.
However, the system did introduce the 3.5" drive as a standard to the 8-bit BBC range and featured all the usual Master enhancements plus a mouse/joystick port. As a school computer - the traditional market - it differed just enough to make it relatively unpopular, lacking the user and 1MHz bus ports used by many educational devices, and being (by nature of its smaller case) somewhat easier to steal and damage. The Compact was discontinued very early on, the introduction of the A305 Archimedes offering a similar 'format' of machine, but with all the benefits associated with Acorn - expandability, speed, and reliability. The original one-box Master 128 continued to sell until 1993...
Olivetti were to get their own back for the Compact - Acorn sold a
branded version of the Olivetti M19 'PC Compatible', a rather dated 8088-based machine.
The Olivetti Prodest 128 can be seen in the kid's film 'Treasure Island in Space' - an Italian production, most likely. The computer is recognizable by its blue and white display.

    "description": "The BBC Master was an enhanced version of the <a href=\"computer.asp?c=29\">BBC Model B</a> providing improved features, but sadly also introducing compatibility problems with earlier BBC systems. \nThese features were: loads more memory such as shadow, sideways and private RAM, 4 sound channels, twin cartridge sockets, as well as several built-in ROM software packages like <b>View</b> (word processor), <b>ViewSheet</b> (spreadsheet), <b>ADFS</b> (Advanced Filing System), a text editor and terminal utilities.\n \nLike the Model B, the system had so many I/O ports that most of them had to be placed under the case. Luckily, they only used flat-cable connectors. \nWhen it was released, the BBC Master met with great success. From 1986 to 1989, about 200,000 systems were sold, mainly to U.K. schools and universities. \nSeveral enhanced versions of the Master were launched in the following months:\n- The <b>Master 512</b> was a Master 128 with 512 KB of RAM and an internal 80186 processor. It could be upgraded up to 1024 KB and ran MS-DOS.\n- The <b>Master Turbo</b> was a Master 128 with a 65C02 as a second processor.\nThe BBC Master and <a href=\"computer.asp?c=729\">Master Compact</a> could be considered the most accomplished 8-bit 'home' computers and among the last mass-produced 8-bit machines. Production ended in 1993.\n \nWhile 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.",

    "description": "In 1986, the 900th Anniversary of the Norman Domesday Book, the BBC and \nthe National Curriculum, amongst other UK bodies, endeavoured to \nproduced a 20th Century equivalent. Recently the Domesday project has \nhad renewed interest, as the sense of producing such an ambitious \nundertaking then storing the results on a strange, and now forgotten, \nformat has been called into question many times since!\nFor old-computers.com readers, the interesting bits are not terribly \ninteresting - but they are scarce. The presentation was viewable on one \nof two platforms - the main, and the one most associated with it, was \nthe BBC Master AIV (Advanced Interactive Video). This isn't an \n'official' term - as far as Acorn and the BBC were concerned, they \nwanted schools to purchase the system in the belief that it was \nessentially what they were used to. The BBC Master was an off the shelf \nMaster Turbo, with an additional SCSI interface (possibly \nelectronically derived from the SCSI interface built into the ACW), and \nan additional filing system to access the LV-ROM.\nThe VP415 LV-ROM was an industrial Philips Laservision player, already \n'programmable' according to the Laservision standards. The storage was \nbroken down into volumes, with data encoded along with the video \ncontent (which can be played separately). The SCSI interface allowed \ndata retrieval but this was also possible via the RS-232 interface - \nand a module to allow the other machine popular in schools at the time \naccess - the RM Nimbus. The actual data format on the disc was \ncontrolled by LV-DOS in the player, and VFS in the BBC series computer. \nWhilst the Master AIV was most definitely marketed for this \napplication, the documentation is quite vague about whether a BBC B \ncould be used, implying that merely the VFS ROM is required!\nVideo from the laserdisc was mixed using a genlock incorporated in the \nbase of the VP415 with data generated by the Domesday applications and \ndisplayed on a SCART monitor.\nApplications allowed searching of film content, further exploration of \nthe information, such as going into a house pictured (within \nlimitations, of course!), and statistical analysis of data gathered in \na project that involved schools all over the UK. It's quite likely that \nmany people of my generation contributed, in some small part, to the \nDomesday project.\nAdditional discs were produced for educational purposes, hoping to \nexpand the applications of the AIV system, but the late 80s was to see \nthe advent of Microsoft's \"Multimedia PC\" standard, Philips' own CDi, \nand many other CD (rather than LD) based systems. LV-ROM, in addition \nto the video and still frames, could store just under 400Mb of data on \na 12\" optical disc - whilst the video would take up more space on CD, \nthe media was physically fragile and was eventually to be rendered \nobsolete with the end of the VP415.\nProjects to restore the Domesday project are hampered by copyright law \nand the restrictions of accessing the data, The most successful is \nLeeds University's CAMeLION project, an emulated system, with some \nPC-based applications. I am undertaking my own 'accessible' project, to \nattempt to make the material useable in a wide range of consumer \nfriendly appliances, but like everyone else, am tied by the fragility \nof the hardware (if anyone has parts for the VP415 I need spares!) and \nof course, copyright law.\n___________\n<font color=\"#666666\">Thanks A LOT to Richard Kilpatrick for all this info.</font>",
