The TRS80 sometimes had edge connector issues (corrosion, etc.)
The normal cure for that (which I never had to do) was to solder a header
plug onto the edge of the PCB and to replace the cables with ones with
suitable header sockets.
For a while, there was a company making gold-plate

My Philips P8450 has PCB-backplane connectors which are a bit like 2-part
edge connectors. The chassis mounted part is similar to an edge connector,
but with a wider-than-normal slot (it looks like it's for a thick PCB. The
PCB mouted part is a plastic strip with contacts on each side (like a
thinner version of the active bit of a microribbon connector). IIRC the
I/O connectors on the PCBs are the same design and I used normal edge
connectors to connect to them, so possibly the backplane connectors aren't
much different to normal edge connectors.
I have never seen these connectors used elsewhere, no idea where you'd
find them.
