Is there a program (freeware if possible) that people use to create schematics?  The reason I ask is that I'm interested in recreating the schematics for a couple of games.  My default was to use Visio, but I was wondering if there was something else that people have used.

Sure, I could just scan them, however they are not complete and truthfully it looks like crap.  One of the other benefits would be to easily find specific relays/switches just by using 'Find:'...

Thanks
