Yeah, pocket calculators and digital watches were in 007 movies when I started flying. They did not have computer logbook programs for the Apple IIe I talked my parents into shelling out $3,500 for in 1983.
For comparison, I bought a nice Piper Tri Pacer just after high school for $7,500. That would make that Apple II a $16,000 purchase in today's money. For a lot of the folks in their late 30's, or early 40's, computer logbooks just did not exist.
