As to being glad to see the STAMP2 in the rear view mirror? You bet. It was some much easier to do things like scale a joystick using signed math. Oh and the PIC chip was many many times faster, more memory for variables, more code space (remember program slots? Ugh! that was painful).

I recall when 95 did a swerve drive using the basic stamp in 2003. I soldered up a board to use a second stamp in parallel with the RC in order to speed up our processing time. It was a nightmare from what I recall.
