@smorgs,
I don't know any pop after 1973.
My computer is okay-ish again. The screen power supply failed, and it may have had something to do with all the crappy dust that was inside the PC box. Two different problems cropped up at one time. What are the chances of that happening, eh?
Anyway I've got a different screen pro tem and I'm up and running.
But it's as slow as the Second Coming.
There's a line for you to work on.
