I have an old Sound and Vision mini-loc sv-1000, it's a digital remote with two memory setpoints, it was a retrofitable unit on a lot of reel-to-reel units. I can't find any info on it anywhere, i do have a basic info pack with it but mine's not working and the info is kinda sketchy. Anyone know anything about them or where to find out more. .i've googled like crazy and found nothing.

thanks!
