I attended a summer computer camp in 4th grade at Purdue University. Ralph Hempel taught us how to use pbForth on the Mindstorm robots. It was just a simple line following robot but my Forth implementation was much, much better than a LabView implementation that I did as a freshman in college (at Purdue, of course =)! I really need to reverse engineer the file format of the pbForth projects. I contacted Ralph a while ago, asking for help to obtain the source from the pbForth files that I found on an old floppy. He never responded. That code is oldest surviving code that I have written! The only possible older code is the "code" (I think it was probably GUI flowcharts) that I wrote for the Mindstorms predecessor (what were they called?) LEGO robots for my 3rd grade computer camp. =)
