modifiable backplane with sockets?

For a project, I was wanting to make some small electronic cards that slide
into sockets on a backplane, and then wire them together on the
backplane. I want the freedom to redo the wiring on the backplane
without having to reprint a new backplane. Do I have to find some old
wire-wrapped backplane from the 1970s, or is there some kind of modern
— and ideally inexpensive — approach to this sort of thing? Maybe I just
need the right kind of sockets mounted on a normal PCB, and then wire
wrap on the back side of those...?

I was thinking like 10 or so pins per card, though maybe I could use
quad chips instead for my modules and go with something like 40 pins.

It is not a data bus — purely analog — so I'm not looking for some kind
of data bus design.
