What ever happened to 'multiwire' (or some such trade name)? It was
a multilayered weld-bonded wiring alternative to multilayer PCBs
in the '60s and '70s and was very rugged, easily implemented with

Gone the same way as wire wrap it seems.

Most VME backplanes utilize a press fit pin, directly into a clad hole,
and it is gas tight in the connection regions and there is no solder
involved. Lasts for years and years.
