I can't even imagine a time when something like that was cutting edge technology.  I wonder what of ours today will seem like that in the future.

It will probably be just as entertaining. There was a time when the transistor radio was cutting age.

Thanks for the video link.  I really enjoyed watching it.


You're welcome. And thank you for posting that first photo of the SAGE which starting this impromptu walk back to the Cold War Years. I can certainly see the importance of those JAN tubes and the significant role it played military equipment during those years.... and why there are so many JAN tubes still around.

One of the types of tubes used in the SAGE was the Sylvania 7236

Sylvania made great tubes. Now the company is a skeleton as the name was sold One of the true great tube manufactures and they also years ago made the best color TV that lasted for 20 plus years. Boy how times have changed

That is exactly why the 7236 tube was called "Computer Rated".  It was in fact used in computers!

That would make one hell of a wallpaper. Hint hint hint...

x3 Hint hint hint, too! Suitable for framing as well; to be hung on my walls; one at work and one at home. With your permission, of course.

So, I would assume that the SAGE computer has good bass extension that is snappy, but might sound a little bit cold at times.

The last time Clayton turn this on caused the San Francisco earthquake...


Yes.
 
OMG. What if the SAGE used EML 5U4G mesh plates instead of the unpretentious Sylvania 7236's. Talk about global warming!!!
 
Guys and gals--I have to return the SAGE. I just turned it on and I think it has a short somewhere. Thank goodness I have some spare fuses:

I hooked up my computer and found a larger resolution, not the original and not wallpaper size, it still requires a little tinkering to get it to look like the image I posted earlier, I'll post it when I get the chance. In any case, if it goes up, you have my permission to use it freely
