As per my Subject line we have a MAT252 with a Kiel II, HDO, and Conflo II as front ends. I'm still running DOS based Isodat software. I really want to use the Windows based Isodat software. Am I truly limited to using Windows NT 4.0 or can I use Windows XP (without buying additional hardware for the MAT252). I know there have been discussions about the Windows upgrade in the archives, but my attempts to find a definitive answer to this question in the archives has been frustrating. I'm in DIGEST mode on Isogeochem so if you could kindly cc: me directly in addition to the normal reply through ISOGEOCHEM I would greatly appreciate it.
