Umm the world is round. ?I suspect all the big
cleaning of old stuff
was done about 10 to 15 years ago, with the advent of digital scopes.
In the past six months, I have come across (in mostly different
locations!) EIGHT different tube type Tek scopes. I will likely only
keep the 565 machine, as all good 70s mainframe shops had a Tek on a
cart tucked away somewhere.
Just a few days ago I came into a 535A and a 567. The 567 is a little
bit of an oddball, as it has the built in Nixie tube frequency
counter. I may end up parting these out, unless someone wants to give
me scrap/parts/shipping value (from 10512). It is a bit rough, so it
is a bit of a project.
In thinking about this again, it was likely the military that spread
Teks all over the place initially. They purchased biblical amounts of
535As and 545As.
