@mattmcirvin@mathstodon.xyz @asakiyume@wandering.shop @rgammans@dice.camp @janeishly@beige.party The teacher who had the computer wrote one of the last slide rule text books ever published! I did learn to use one. I remember dad bringing home the expensive calculator he had brought for his medical practice - $50 in about 1970 with a 6 digit display & a button to push to show the 6 highest digits. Basic arithmetic only, suitable for calculating medical bills.
