Now I've hijacked an entire thread. But hey, it's all about me!
I do remember BW TV.
I didn't see TV until I was 11, and that was because our town didn't have it until 1954. Honolulu had it about a year earlier. Then we had one channel, CBS, and we got it via a signal that came from Maui, hit a reflecting antenna up on Mauna Loa, which sent it downslope to a tower that I could see out the back of our house. When it was windy on Mauna Loa the reflector shook and sometimes went out of alignment.
Yeah. We old guys have dealt with old tech. To crunch the numbers for my PhD thesis I punched (and verified) nearly 10,000 cards on an IBM keypunch. Talk about mind-numbing (and noisy). The cards went to a System/360 for overnight processing. I had to provide my own tape, which I got from a surplus place and was marked "Saturn V launch data."
One more old-days thing. Although I understood about logging into a computer via modem and teletype, I certainly didn't understand networking. In the early 70s, I was visiting a friend who was working at Bolt, Beranek and Newman (BBN). He fired up a little TI teletype and said, "Watch this," and proceeded to log onto the BBN PDP-10 and then without hanging up and redialing, he logged into half a dozen university systems around the country. I didn't get it at all. I said, "Oh, interesting."
