I hope so, I've got a dozen or more circular slide rules,
several regular engineering slide rules, and even a Curta
calculator. The Curta is a hand cranked mechanical
calculator that looks like a hand grenade. Certainly a nice
HP or Ti calculator is faster and more accurate, but harder
to use in flight.
