I have a well maintained bamboo slide rule in a drawer somewhere here.
Never liked the metal ones. It got me through college to a BSEE, but
shortly after that, on my first full time engineering job at a small
company, the manager bought us one of the new HP pocket calculators to
share, then he added to the collection with newer models every year. Within
five years, I was able to purchase my own. Yes, it and a few other HP
calculators are around here somewhere as well.
