When each of my daughters turned 10 (within the last 10 years or so) I gave each of them a TRS-80 Model 100 and taught them basic. One really took to it and used it to write software for a science fair project on genetics - the judges were of the right age to appreciate it (although she didn't win anything!) In any case, its a lovely computer with a pixel addressable display, which was perfect for doing newtonian physics demos for extra credit in high school physics... (But they make lousy terminals at 40 col.)
