BeebMaster's
Domesday
Machine
SCSI
Ribbon
Cable
The SCSI board inside the BBC Master connects to the back of the Laserdisc player via a standard 50-way SCSI ribbon cable.
The lead in the picture above is the one I am using in the BeebMaster Domesday Machine. It has some additional connectors along the lead as I think it was originally used in a server with multiple hard disc drives, but it works fine with the Domesday System.
