When I was an undergraduate:
  1. The waelty engineering students had a Dietzen Log-log Duplex Deci-Trig slide rule @ $28.00 plus tax.
  2. The less wealty students had a table of 4 place lgoarithms @ $0.25
  3. The truly destitute ones memorized their classmate's table of 4 place logarithms.
Ohh..and BTW a textbook could be had for $15.00 or less - NEW!
They just don't make students like they used to make 'em

Wow I am way too old. When I started in electronics we had to learn to use a slide rules because those new fangled calculators were just a fad. :)
