content: Thanks for yet another interesting video. I was amazed at how much stuff there was in that bit of kit. I for one would be very interested in seeing you do some measurements on some of those 'blocks'.

content: I would like a teardown and explanation on how the rf coponent works.And than you couls build some good experiment with them.By the way where you find this dumpster at bell labs?

content: Now that is a teardown looking for parts. The question is, was the dumster rated for >10 GHz BW equipment?I would be really interested in description of 26 GHz part and other high frequency components merged with motors.

content: Oh god, that plugin was in the complete mainframe in the dumpster, and he left the mainframe there 'because it was too heavy.'(falls off chair, drags self to dark corner, curls up in fetal position and cries.)Oh well, I'll just assume the thing was hopelessly dinged up, and could never be resuscitated. Please don't anyone say otherwise. This way I can watch and enjoy such a beautiful system being scrapped for parts.As opposed to watching it and suffering irreversible psychological trauma.

content: The mainframe was not good. Rusted, snowed on, and dirty. I had already cleaned the front of the modules before filming.

content: Quote from: TerraHertz on February 14, 2015, 11:36:01 amToo late, it already happened to me.70000 series mainframes and display sections are available on the cheap.It was a superb spectral analysis system and those modules would probably have found good use if sold.Like your comment on the RF section: "Too beautiful to destroy".

content: Having a HP 70000 system that misses the RF section, i had a heart attack hearing that you found such modules in the dumpster. Would wish that happens to me. Would volunteer to test whether the RF section is still functional. Very nice video about the internals of those modules!
