The earliest Lisa prototypes had 50-pin edge connectors for the I/O
expansion cards. Sometime between 7/81 and 2/82 the Lisa got the
pinch-fit, 56-pin edge connector for I/O expansion cards that it
eventually shipped with. The collection of diagrams at DigiBarn (from
which the flickr image was nicked) shows this evolution pretty clearly.
Ah, there we go! Thanks for that link! :-)
