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 for the original AIV SCSI board which both functions as and resembles the original. The project and design are open-source hardware and free to use.
