This is the last version released of the VVCR system sofware.  The disks are self booting and self installing for all VVCR models.

The VirtualVCR or VVCR was Drastic's first Digital Disk Recorder.  Based on Intel 486 CPUs with a custom built Unix like operating system, the VVCR used Matrox video and compression boards to save high quality SD motion JPEG frames to a standard FAT32 disk or custom, shared disk operating system.

This is one of the original VVCR advertisements from 1995.
