Found a 1990s wiring diagram for a nav system and it looked like a kid drew it

I was digging through old files at the hangar and pulled out a paper manual for a GNS 430 from like 1995. The wiring diagram was all hand-drawn with pencil, super messy, and someone had written "good luck" in the corner. Back then, I guess you just had to trace every line and hope for the best. Now I pull up the digital manual on my tablet, zoom in, and have the exact pinouts in two seconds. The old way felt like solving a puzzle with half the pieces missing. Anyone else find these ancient docs and just laugh?

That "good luck" note was the previous tech's honest final instruction.

Feel that in my soul.

I mean, that hand-drawn diagram was probably the official one from the factory. They did a lot of that back then before everything was CAD. It was a puzzle, but it was the only puzzle you got.
