1.) I watched Neil Armstrong walk on the moon, live. On a black-and-white TV.
2.) I remember the invention of the cassette tape.
3.) When I first worked at a TV station, it was before VHS tapes existed. The new thing was U-matic (3/4") video "cassettes".
4.) I learned electronics using vaccuum tubes.
5.) I remember when calculators didn't have seven-segment displays, and used nixie tubes.
6.) When I was first programming computers, we had to use punch cards and paper tape. The PC didn't exist yet, and hard drives were still a ways from becoming commercially available.
7.) My first real programming job was rewriting the system for a computer that had magnetic core memory.
8.) Marylin Monroe was still alive when I was born. JFK was president.
9.) I used to laugh at Topo Gigo on the Ed Sullivan show.
