When I was developing the MiniVex Pedal I, the foot pedal add-on for Vectrex and Atari, I received a suggestion to make multiple units link up, so that more than one button could be interfaced with a pedal (ie:gas and brakes for driving games.) So I've been hemming and hawing over how to add jacks to an already crowded selector box, among numerous other details, and...just staring at them last night, the setup in the photo happened. No revisions whatsoever. And it works perfectly.
Over TWO MONTHS since I received that suggestion! SMACK! (Sound of palm slapping forehead.)
Does wisdom increase with age? I'm having serious doubts.
