You folks are all young sprouts... when I was in H.S.
(1938) our AV
equipment was a wind up phonograph (disks, not cylinders,) and a lantern
slide projector. Once someone from Bell Telephone brought in a movie
projector and showed films! Calculations? they were done with a pencil on
"foolscap". And no, I didn't have Socrates for a teacher.
I went through HS on a slide rule. Someone brought in an electromechanical
calculator to my math class, and I fell in love with it. <sigh>
ps Where did "Foolscap" get its name? E-mail me... (extremely off-topic)
