Same here. I was 8 or 9 years old and couldn't understand how chips worked. They were just sort of magic to me, so I wired all my solutions without chips. It required a massive mess of logic gates to solve things like the Ventilation Shaft and Minefield puzzles in level 4. The signals puzzle in level 5 was as far as I could get... but it got me hooked on algorithmic problem solving. Edit: to get an idea of the complexity of the puzzles, here's a link to a walkthrough of level 4: http://mysite.verizon.net/thomasfoote/DQ/id28.htm http://mysite.verizon.net/thomasfoote/DQ/id28.htm
