I went to engineering school in the transition period between slide rules, etc. and computers/calculators (late 70s/early 80s). So I never used a slide rule. Here is a cool Texas Instruments Ti 59 I bought at an estate sale. The guy was an engineer for Dow Chemical. Included were several dozen program cards for various things he did. Most are dated 1980. And it all works - even the thermal printer! I was always an HP guy and used similar programmable HP calculators over the years.
