I remember the [Video Backup System](http://www.hugolyppens.com/VBS.html) for Amiga advertized in Polish computer magazines of late 90s, "store hundreds of diskettes on a single VHS tape!"

I seriously considered buying it (and a VCR since I didn't have one...) before I got my hands on a cheap CD-ROM drive – and to this day I don't know what I have missed and if I should regret it or be happy.

First, let me ask the solid objectively answerable question: it connected by SCART or RCA (composite video, "phono plug") to the VCR, but what interface did it use on the Amiga side? It didn't have any built-in video, or analog inputs, so the analog data had to undergo some rudimentary conversion to digital in hardware (before being passed through Reed-Solomon Error Correction program running on the Amiga). What was it?

...and then let me ask for comments, how did it work out in practice (as "user experience") – because I never knew anyone who used it, and I wonder if it was half as good as the hype in the ads.
