I'm old enough to remember hand-etching prototype boards at my first job out of college because commercial prototypes cost so much. At that time, the big deal was the PCB milling machines for companies that needed prototype same day.

Stuff like this makes me feel old!

My shame though - is that I haven't finished soldering the plugs... (Because I want to use pigtails instead of soldering them directly on the board)

Now I can get the same to my door in under 2 weeks for $60. And they actually test the boards!
