As far as I know you need the Prins software, a computer running win98, with a serial port (or if you are a computer person, get it to pretend to be Win98), and a link lead which is about £30 from Poland. I bought an old cheap win98 laptop just to mess with it = £40 on Ebay. Not sure how well it will work yet as it is too bloody cold!
Simon (LPGC) might be your best bet for info and perhaps software.
Sounds good I've got an old laptop or two spare I can use. And, if I ever do mess things up I've a couple of spare gas ecus that work too. Any chance of a link to the Polish connection please.
