I don’t have a slide rule, but do have a Curta Type II calculator in its original box with original instructions thta I bought in early 1970 to do estate and tax work. In 1971 the first of the electronic calculators came out, making my Curta instantly obsolete, so I decided to keep it as a curio that might someday be very valuable. Right now it’s worth about $1,300 vs. the original price of about $150.00.

When I was in college (grad.1972), the business dept got an “electronic” calculator. Cost $400. All it could do was add/subtract/multiply/divide AND square roots. Heaven!

The real kicker was that only grad students and faculty were allowed to use it.

Right now it’s worth about $1,300 vs. the original price of about $150.00.

Meaning it has more than kept up with inflation. $150 in '71 dollars would be about $850, today.
