[re old IBM mice]
  jeez, i just round filed dozens of them a while back!
the buttons start
 getting dodgy after long term use.  
So did I!  Someone brought in a paper grocery sack full of them and wanted
to sell them.  When I said no, they just left the shop, and left the mice
behind, so I chucked 'em.
Are you sure that's not a PS/1 mouse in the photo?  The ones I trashed were
exactly like the photo, but I didn't think they were the really early mice.
