   I think you're correct that it's a Logitech, but I'm not positive.  
What I am positive about, though, is that the 3B1 uses a 3-button 
mouse.  If memory serves its connector resembles a modular one but with 
a slightly more elaborate locking mechanism.

   Very cool.  I sold and serviced them in an after-school job in 9th 
grade.  I spent every spare moment bouncing between the 3B1 (actually a 
7300...nearly identical) and the DEC Pro350 we had in the store.
