Steer well clear my friend, it just isn't worth it. I bought it for my Blizzard PPC system and they never ever got it to work. As far as I know it does work on Cyberstorm systems but there is no support for either serial port or parallel port. So you can run a fair few programs but cannot print from them and worse still cannot get on the internet (with dial up anyways) with it..... so whats the point?
I managed to sell mine for £50 (cut my losses) but a lot of people were left with a CD that was more useful as a beer mat :-(
