Does the black connector housing have ridges on the top and bottom that
prevent a normal DE-9 from mating with it? Or signs that such ridges have
been filed off? If so, you have an early backplane. I wouldn't expect to
see that in a 2/10 or XL. The early Lisa mice used a strange DE-9 variant
that I can't easily describe. In order to use the later mice on it, you
had to either file off the ridges on the Lisa connector, or cut notches
in the metal shell of the mouse connector, and either way you ended up
with nothing to retain the connector.
