Video Backup System (Score 1)

old serial (intended for amiga) video backup ntsc decoder. http://www1.omnitel.net/savel/amiga/hardware.html that was one, back in the amiga days, the VBS - Video Backup System, did very reliable backups at about 40 meg per hour with runtime compression. that was back in 94. The theory is simple enough, 1 volt peak to peak video signals are fed into a diode decoder on the serial port. white on the video means a one in the serial. VBS used 4 data columns with the last being for error correction and the top and bottom of the video had syncronize info. it worked very well, i remember backing up about 4 gig or more this way. the amiga had NTSC composite out on all of the older systems, as pc's dont, there would have to be a standard.
