I had forgotten all about this until you mentioned the computer chips, but back when I was developing Ektachrome (process E-4) a few times a month I got to where I could tell water temp within 1 degree F. by dipping my hand in it... I still used a thermometer, especially to check first developer since that had to be within 1/2 degree. But all the chemical bottles would sit in a sinkful of water that you constantly had to add hot water to to keep it the proper temp (85 degrees if I remember right). I'd add water until the temp felt right and then check the thermometer... after a year or so of doing this, my guesses as to when to stop adding hot water would be right on the money.

After all these years, I can still get within a degree or two when mixing up water to add to the aquarium. So I guess I'd definitely have to say I believe the story about the guy with the frame tubes.
