we had worldwide digital audio in 1944!!! I was at one of the very first public demos of digital audio by Bell Labs in 1962 ... and never dreamed that it was then older than I was. Doug McDonald |

The astronauts on Apollo 12 having fumbled the TV camera, letting it aim at the Sun, burning it out, didn't help. After that, the public being unable to watch live TV from the moonwalk, lost interest in that mission...

I watched a news piece on the anniversary of the Apollo mission today on my newly acquired late 60's Setchell Carlson Class room TV/monitor. I'd guess it has not been worked on in a long time yet it still works like new.

Yes, worldwide digital voice communication in 1944 via shortwave radio.
Google SIGSALY One notes that we have had transoceanic digital text since 1866 and transoceanic digital text by radio since 1902, just with human ADC and DAC. SIGSALY was fully electronic (except for the encryption.) Doug McDonald |

The 40s era actress, Hedy Lamarr, who was actually an Austrian Jew, Eva Marie Kiesler, was a whiz in other areas as well. She helped develop some concepts that helped spur on digital technology. She hoped her discoveries would help defeat the hated Nazis, but he discoveries were about 35-40 years too early...

In case you have not seen it, back in 2009 Stan LeBar was the featured guest at the Early Television Museum convention. On the last day of the convention he toured the museum, some of us had cameras and recorded the tour.

Walter
I still hear Walter Cronkite in my head. One of the many voices I hear in my head besides the voices emitting from my keyboard.

Oh, another event around this time for my family is that we adopted a kitten, "Cricket" that we then had for 17 years.

We lived in Minneapolis, and Golden Valley TV had just serviced our Zenith color roundie combo. I was in the basement watching reruns on an old Admiral black and white, and my dad called us all into the living room just before Armstrong gave his famous remarks. I was 8 at the time, and had seen the launch at school (summer school, half days)

I was 10, and I don't have any clear memories of watching the Apollo 11 coverage, but if we watched anything at home, it would have been on our new GE 21" color TV in 1969. I still have the TV in my living room. It has a green cataract around the outside and the picture is overly green now, but then it was a great TV. We used it until around 1986 when it was replaced by a cable-ready Magnavox.
It had the "automatic warm-up" circuit to keep the tubes lit halfway. I worked on that TV many times and I have lots of spare parts put away for it. It's one of the heaviest table model TVs I've ever seen. Metal cabinet with fake woodgrain and a heavy metal chassis. We also got a rotating antenna. It worked great, and we could pick up Charlotte and Chapel Hill. |

If the image is too green even in the center where it is not discolored then it probably could benefit from a gray scale adjustment (ie screens and color gain controls adjusted for an untinted monochrome picture).
Those green cataracts are not all that hard to fix either.

Our 1963 Motorola (heavy metal) 19" was pretty bright but images were still hard to see, I was almost 6 and a bit confused like others my age. Dad recalled it being on a weekend.
We had moved from SanAntonio to live at my Grandma's in Penna. just two months before. Likely we watched it on WFIL-TV 6 from Phila, the clearest channel from the stacked conical VHF antenna. It was a field (sand)stone house deep in the woods, only some fans were needed to stay cool then, great times.
