The LVL true double density printed circuit board offers an amazing 1 ,474,560 Bytes of on-hne storage, on a twin 80 track double density drive. Removed is the 8271; (it is not capable ot supporting double density). In it's place, a small printed circuit board with a new disc controller and support circuitry provides a much improved data retrieval. This drastically reduces read errors by using a phased locked loop data separator, which is superior to the standard window circuit. Your BBC micro will now recognise the media density in the drive, and inform you if it is correct. You may define what density you require, 40 or 80 track, and which sides of the disc to use. Tlie device gives complete flexibibty and comes with an Eprom containing firmware; manual, and a 40/80 track utilities disc. On a dual drive it is simplicity itself to copy existing software from single density to double density. • Double Density • 40 or 80 track • Automatically • Own PCB with checks for correct seperate 8Mhz density clock • No 8271 (RareS • Simple to fit expensive) • User definable • Utilities provided density • Defaults to single • Phase lock loop density on power data separator up QLcircuit. -

For the first time the exhibition is organised directly by Redwood Publishing, the publishers of Acorn User, and features several innovations. There's a series of seminars covering aspects of computing from wordprocessing through music, to programming. For teachers and the trade we've introduced a specific first day so people get the chance to concentrate on those special interests. -
TELETEXT and ITS USE in SCHOOLS by GARY DAVID
TELETEXT AND ITS USE IN SCHOOLS by GARY DAVID COOKE A Master's by Course Dissertation submitted in partial fulfilment of the requirements for the award of the degree of MSc in Computer Education of Loughborough University of Technology, January 1989. Supervisor: Mrs M P A Green by GARY DAVID COOKE 1989 ABSTRACT Television teletext is a public viewdata service, a British invention in the nineteen-seventies, that was envisaged as a data store for a national computer literacy project. This dissertation examines the devel opment of the technology and its benefits to schools. Although both the IBA and the BBC transmit a teletext viewdata service, it is the BBC's CEEFAX that has had the greatest influence on education. After launching a computer-literacy project along with its microcomputer and television transmissions, the BBC developed its teletext service to provide both information and a transfer ·of computer-based learning materials. Reception of the latter became possible with the BBC microcomputer teletext adapter. This, in turn, gave rise to the the CEEFAX Telesoftware Service, a section of CEEFAX dedicated to the provision of electronic data, primarily for education purposes. The educational achievements of BBC Telesoftware have been barely documented and this dissertation largely has that as its aim. i DEDICATION This dissertation is dedicated to Jeremy Brayshaw, the Telesoftware Organiser of BBC CEEFAX. When the time came to submit this work for final assessment the BBC introduced sweeping changes to the format of its teletext service and this necessitated the closure of the BBC Telesoftware service. During the time that it had been in existence, the BBC Telesoftware Office had. -

A computer for individual use, typically, is a box with separate keyboard and monitor, or else a flat notebook with a fold-out screen; employs a Microsoft operating system, on an International Business Machines(IBM)-derived hardware architecture, usingan Intel-derived microprocessor; and is primarily set up for use as an office tool, though it can be coaxed into performing many other tasks. Compatibility or interoperability with thesenormsand expectationsisa principal consideration for office, educational and home users. The `PC' did not reach its commanding position through legislative intervention or formalized regulatory guidance.
