To connect to the Bubble Display module, I mounted it on a piece of Veroboard, with the rails cut between the 2×6 pins. I left one row of extra holes on each side, and mounted some 90 degree header strip there, exposing the 12 pins at right angles to the display. I then took two length of 6 strand ribbon cable, put 6 way Molex connectors on for plugging into the display. But on the other end of the ribbon, I put 12 individual connectors on, this way, it was easy to match the bubble pin number with the correct shift register and pin at the board end. I do need to find some nice soft flexible cable though, all the stuff I seem to have is really stiff, and doesnt like being bent at certain angles!
