the discs would become unreadable as computers capable of reading the format had become rare and drives capable of accessing the discs even rarer. Aside from the difficulty of emulating the original code, a major issue was that the still images had been stored on the laserdisc as single-frame analogue video, which were overlaid by the computer system's graphical interface. The project had begun years before JPEG image compression and before truecolour computer video cards had become widely available. CAMiLEON However, the BBC later announced that the CAMiLEON project (a partnership between the University of Leeds and University of Michigan, led by Margaret Hedstrom and managed by researcher Paul Wheatley) had developed a system capable of accessing the discs using emulation techniques. The CAMiLEON project transferred the text and database files stored on the Domesday laserdiscs to a Linux-based computer using an SCSI connection to the player. Images, stored as still-frame video, were digitised at full resolution using video capture hardware and stored uncompressed, ultimately requiring around 70 GB of storage per side of each laserdisc. A modified version of the Free Software emulator, BeebEm, was then used to access the archived data, with enhancements introduced to support emulation of the Turbo co-processor, SCSI communication and laserdisc player functionality. Videotape Digitisation Efforts Another team, working for the UK National Archives (who hold the original Domesday Book) tracked down the original 1-inch videotape masters of the project. These were digitised and archived to Digital Betacam. Domesday 1986 A version of one of the discs was created that runs on a Windows PC. This version was reverse-engineered from an original Domesday Community disc and incorporates images from the videotape masters. It was initially available only via a terminal at the National Archives headquarters in Kew, but was published on the web as Domesday 1986 (at domesday1986.com) in July 2004. This version was taken off-line early in 2008 when its programmer, Adrian Pearce, suddenly died. Domesday Reloaded In 2011, a team at BBC Learning, headed by George Auckland, republished much of the Community disc data in a short-lived web-based format. This data comprising around 25,000 images was loaded onto the BBC Domesday Reloaded website which went online in May 2011 and offline in June 2018, being hosted in archived form at the National Archives thereafter. The data extraction underlying the Domesday Reloaded site was carried out in 2003 and 2004 by Simon Guerrero
