“Thermostats, doorbells, refrigerators, washers and driers, dishwashers all were better before chips.”
Thermostats! Remember the ones you just turned up and down? Huh? Great times.
I have one on my wall. When I got my last Mastercool installed, they tried to get me to update to something that looked like it came out of an F-18.
I said no, and they used the old one. Easy peasy.
Yep, just two joined strips of different metals with different expansion coefficients that curled and uncurled to turn the air conditioner or heater on and off. Good times.
