I tried building my own cable for a CVS Blue, following the directions for the Centronics / USB cable.
Unfortunately, I don't have soldering tools or very steady hands, so I tried (please don't laugh) holding the cables in place with hot glue alone.
This didn't work at all, and actually net me a burn on my finger from the cable when I kept trying to get it to work - seems something didn't go right.
I'd be willing to compensate someone for a premade cable, as well.
I can be reached through here, or via [dhmo at pixelechoes dot net].
Beware the horned chocobo. o.O;
