Image #1: Rough sketch of MK14 VDU connector pin numbering seen from top (component) side. I made some quick measurements to verify that the 'a' row is definitely the row closest to the PCB edge and the 'b' row is the row further away from the edge.

Image #2: Top side showing '1' at right hand side and '32' at left hand side

Image #3 Underside of connector area

Image #4 The reason mine has a DIN connector fitted. In 2013, after the VDU card had languished in a drawer for at least 30 years, I took pity on it and connected it to a PIC micro evaluation board programmed to emulate a 512 byte block of RAM which was preloaded with a static message for the VDU to display. The aim was basically just to see / show the VDU card working without having to connect it back up to the MK14.
