> Which, by the way, has really marvelous ramps and responsiveness for that encoder -- it's silly-fast and efficient to give that knob a twist and dial in exactly what I want for a timer.

Omg I am so jealous. All the appliances I use at home or family have horrendous UIs.

And I am really trying hard to find appliances with passable UIs. It's impossible those days.

And for the few that have a rotary encoder, they are barely usable, and used for anything but selecting the time.

I have contacted companies and offered to write the code for free to fix theirs shitty knobs. But they all refused or didn't bother replying.

Anyways I am off topic.

It's old -- I'd guess from the mid 80s. Branded Kenmore and made by Frigidaire/Electrolux. It was free. The controls themselves were basic electromechanical things -- the clock/timer doesn't do anything but display time/timer and beep.

When I first got it, I assumed it was driven by AC as many clock ICs once were back in those simpler times.

But then I discovered a small low voltage DC power supply when I was in there installing a PID controller for the oven, so it may actually have something resembling software. Maybe.

And yeah, unresponsive physical controls are a pox. I'm not sure what method you used, but perhaps contacting the companies that design and build the boards might be better than contacting the companies that buy the boards and install them.
