Nice Jens, a "tip" of the ol' index finger on this one... I love how the teacher is thrilled to have their one commodore up in front of the class, the "latest" tech for sure! Hell, my school, Colorado Technical University, just installed our first smart board!
Smart Board Technology
I used to run a demo group on the Commode 64 computer.
This web page has screen dumps (yes, they're really called that) of several of my demo programs, along with the demos themselves and a PC emulator (that essentially turns your pee-cee into a C=64) that allows you to run them.
