This disc set (which is without doubt the rarest AIV disc made by the BBC) covers the square mile ‘City of London’ and was produced by the BBC’s Interactive Television Unit in association Continue reading The BBC AIV City Disc set is found!→

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→

This project provides a drop-in replacement Continue reading Replacement Acorn SCSI AIV Adapter board→

This project provides a modern replacement for the module made with durable, industrial-grade parts.  The replacement can be simply dropped into the player and requires no alteration.  As well as fixing existing broken players, the Continue reading Philips VP415 Replacement Front-Loader Module→
