Ok, here's a scan of the box with some specs..I hope it helps. But as I said
before, I have used both products extensively, I have an old used T-Port laying
in a drawer. It is inferior to Turbo Port both because its chip is slower and its
software is primitive in comparison. I hope you can read this primitive scan. I
don't have time to clean it any better right now:
