Oops, I'm wrong on my guess.

Maybe adding some hyphens will make my description clearer, "cheap
edge-of-the-epoxy-circuit-board connectors." By cheap I mean that to
manufacture these connectors pads only need to be printed on the edge of
the epoxy board which saves the cost of making all those pins and the
plastic housing and attaching that to the board. I thought that Apple used
this type of connector for PDS slots, but I've never seen the inside of an
SE30, which was the computer you were discussing.

Cowering in the corner I plead:
