with the BBC Micro supplying "question-and-answer frames" in interactive training course material. The Polymedia PCL 1000 also offered a combination of BBC Micro and Sony Betamax video tape recorder bundled with interface, single disc drive, colour monitor and software for £2,450. Earlier competitors included the Felix Link interface from Felix Learning Systems, supporting laserdisc, VHD video discs, U-Matic tapes, with VHS tapes promised, along with Cameron Communications' Interact B system offering touchscreen control over a Thorn EMI VHD video disc player. Acorn's success in the interactive video market was reportedly hindered by Acorn's financial difficulties of 1985 putting the company's "support or commitment" into question, even leading to the BBC taking over the development of the Domesday Project's retrieval software from Acorn. Consequently, a contract for 1500 machines with Lloyd's Bank ended up being signed by Video Logic, and other potential customers had not progressed beyond trial purchases of Acorn's machines. By early 1988, "fewer than 2,000" Domesday systems had been sold, with the total price of the system being around £5,200. However, a voucher scheme had been in operation, reducing the purchase price to £3000, and this was to be extended until the end of that year. Subsequent Acorn machines were also featured in laserdisc solutions. For instance, a system was offered by Eltec Computers and the British Nuclear Forum consisting of a BBC A3000, LaserVision 406 player, genlock card, and three discs designed by educators at Newcastle University aimed at secondary schools. The system cost £1899. Some software on the RISC OS platform also supported use of laserdisc players such as the Key Plus data collection and analysis software for the educational market. Oak Solutions' Genesis product supported use of laserdisc hardware, with The Battle of the Somme title, produced by Netherhall School in conjunction with NCET and the Imperial War Museum, incorporating "Laservision material which really brings the project alive" and offering "potentially a new beginning for that old Domesday system".
