Quoted from pin2d:- Best School Project Ever
I agree! Can't ask for a much better project than a Big Time - 5 Magic Lines, two super cards and much more.
Having a little experience (https://pinside.com/pinball/forum/topic/1950-bally-turf-king-one-ball-horse-race-game) teaching kids about fixing games, I believe that there are few things more valuable to a young mind than learning how machines work, how to read a schematic, how to fix their own electrical and electronic stuff (and hopefully applying those lessons later in life, too).
