In 1989 Apple produced a LaserDisc based multimedia kit for American schools similar to the BBC’s Domesday National disc (although with less focus on data and more on video). As with Domesday, the Apple Visual Almanac is an example of early interactive multimedia applications using LaserDiscs to present video, pictures and sound with unprecedented quality. Information about the kit and Continue reading Details of the Apple Visual Almanac added

The Acorn AIV Master computer used by the Domesday project was fitted with a specific SCSI adapter card in order to connect the Philips VP415 LaserDisc player to the computer. As there were a relatively low number of Domesday systems sold (and very few survive) these cards can be difficult (and expensive) to source. This project provides a drop-in replacement Continue reading Replacement Acorn SCSI AIV Adapter board
