I've still got my first calculator, a Jeppesen model CR-3 computer. I did buy a TI 2500 when they first came out, 1972. To derive a square root a series of division operations had to be performed to extrapolate the answer. I showed an old guy co-worker how to calculate interest rates the easy way. He started borrowing the machine to do just that. I watched him the next day run the figures then turn to paper and pencil to check the answer, bless his heart.
"When you runs out of fingers and toes, you applies for social security" Albert the alligator as retold by Walt Kelly We shall not go into proper counting as directed by Brother Maynard as it is quite silly.
I took courses in school that required "slide rule accuracy" I always found slide rules fascinating, it was possible to see how answers were derived.
Just remembered something I did as a kid when we'd visit back at the old country place: Crank up water from the cistern.
How about the tools you have in your garage?? I am not talking about what you remember but what you all still own????:lol:
Hmm like that special open end box wrench I heated and bent so I could loosen the distributor bolt on old GM's?
