I can still smell the ammonia from paper fresh off the mimeograph machine. "Blueprints" were blue and smelled of ammonia. There was no color TV. I walked 1.3 miles each way to school. I used a slide rule for AC circuits. The first computer I saw was in college. They used paper tapes and punch cards. "Mini computers" were DEC Vax machines with switch inputs to enter machine language commands. A "4 banger" calculator (+-*/) was $100.
Later there were 8" floppies and 30MB hard drives as big as wedding cakes. But by then the dinosaurs had disappeared and men became our biggest threat.
