The Videodisc Filing System ROM is an integral part of the Domesday System. It provides the hierarchical filing system, similar to ADFS, which is used by LV-ROM laserdiscs, as well as a set of commands controlling the playback functions of the player. It contains the code to drive the trackerball or mouse and controls the configuration settings available in VFS. I hope you will click on the picture links above to learn more.
