My first tv had knobs. Clunk-clunk-clunk knobs for the channels. There were 2 of them, one for UHF and one for VHF channels. It was in black and white. But that didn't matter, because half of the shows on tv were black and white reruns anyway (bewitched, my three sons, etc). I think it was a 6" or 8" screen.
My first video game console was Pong. The original.
My first "remote" had a 5 pin cable running from it to the VCR.
My first online experiences were with a modem. My first modem was 300 baud, but it could do 50 baud if you wanted to connect it to TTY.
The first time I used a computer, it was a teletype machine--an electric typewriter attached to a mainframe with a serial cable. We played math games. We would patiently wait for the typewriter to type out a math problem, and then we would type the answer. I was one of two kids who ever saw that thing in my elementary school.
When I was a kid, all of the cereals still had "sugar" in the name: Sugar Corn Pops, Sugar Smacks, Sugar Frosted Flakes, Sugar Crisp.
The first rap song I ever heard, in junior high school, was
White Lines by Grandmaster Flash. When I was in junior high, people actually had breakdance battles at teen clubs. I carried around a beatbox and cardboard around my neighborhood and would hook up with neighborhood kids to breakdance.
I remember when Cracker Jack actually had an actual toy surprise in them, and not some temporary tattoo or other paper product.
