LOL - my 72 AMC Hornet had one of those 8-track players.
That electric calculator was a big deal. Our office had ONE - for special projects. Every mostly used hand crank calculators.

Our first computer games had to be loaded by cassette tape. Took like 30 min or so THEN you could play. And we had like 2.
