Yeah - it was pretty simple stuff. You entered the number of seconds for the robot to move
in fwd, rvs, left, rght, or backwards to navigate a course. The headlights just turned on or
off based on light levels. Nothing fancy. It had zero sensors except for the LDR.

The average person had to re-program it around 4 times to make it through most simple
courses, but it was tons of fun. You could do the same thing with around 50 lines of PBP
code on a PIC. It was several hundred lines of 8749 assembler. Boy have times changed.
