Well I had to engineer a new connector. The main PCB runs almost 2/3 of the length of the 'nose'. Then there's phosphour-bronze fingers that I had stamped in China which are tipped with gold contacts - all soldered together during the reflow process. The physical support - the black plastic block of the old connectors - is built into the lower case half and 'nose' cover. The case is in three pieces: bottom, main top and connector top.

There aren't enough old modules kicking around to cannibalize, just to extract an already 30-40 year old part from.
