BBC Master AIV
User Guide



I bought this in summer 2010. It came with another Domesday-related item which I'm keeping quiet about for the time being!

This is the user guide for the Master AIV itself rather than the Domesday Discs specifically, which warrant their own guide which still eludes me. It is very handy and contains details of all the VFS commands, including OSWORD and other OS calls, the LV-ROM disc format and the control codes for communicating with the player.
