Hi Michael, Check out www.dontronics.com Don may be able to help you with a solution -- worth a try. I think there is some mention on his web site regarding software that works with the ITU hardware. Sadly, Chris Sakkas died circa 1998. He was way too young and was a great person to have in the engineering community. Good luck in your quest -- hope you can get it working on Windows XP.
