Console Schematics
Schematics for consoles are notoriously hard to come by. You may occasionally find a badly scanned copy of a badly photocopied copy of a badly drawn third party SNES schem, or you might know a guy who knows a guy… But that's more or less it.
I had to take matters into my own hands when it came to the PCEngine, and the results of this crazy note-taking and painstaking trial and error are below for your enjoyment.
And maybe other consoles as well. Add 'em if you got 'em.
