I just watched the NI tutorial "A Simple Thermocouple Measurement - 1994 and 2004". It shows writing a VI in LabVIEW 7 vs. LabVIEW 3.1. It got me wondering just what the really early versions of LabVIEW were like. Seeing as the early versions were on a handful of floppies, they wouldn't be a big download. I even have an old Mac in storage, so LabVIEW 1.0 would be an option. Anyway, I can't see how releasing the 1.0-3.1 versions as freeware could possibly hurt sales of 7.0. Every year at NIWeek they have old machines running the old software, so NI must have a few copies that are easy to get to. Maybe have the person in charge of that booth add them as a bonus on the 2004 NIWeek CD.
