[sdiy] where to get 3M Scotchflex sockets and strips?

What is strip board? That does sound like something I would like.

The 3M scotchflex socket system was eye wateringly expensive.
It made a lot of sense when prototyping digital bus based systems.

I made a lot of Eurorack size cards for GESBUS/Half VME, etc. that
would be alpha trialed before an actual PCB was made.

The comments here so far show that most of the reasons for its existence
are now gone.

Now, about this strip board, is that a wire wrap thing? Or is it "push to
clip & contact" like the 3M stuff?
