Hi mate,
Haven't had the pleasure of working with windows 7 and these dataloggers yet, we're public sector you know! I've got drivers for xp which were a bit nasty to get working to start with but eventually managed it. I can forward those to you if you wish. As for buying or receiving your relics i'd have to have a chat with our science department as we are slowly getting them toward the door, the fact that new dataloggers are out of our price range is the only real reason for keeping them! Phoned Easysense for technical support early this year and they pretty much laughed at me but at £140 a unit or whatever they quoted it was worth the 99p serial to usb adapters and a few hours of hassle.
