   Take a close look at how Logitech describes that mouse (on its box or its
   manual).  Some are just called "serial", some are called "serial or PS/2".  
   If it's PS/2, it should be able to plug into the mouse port.  I have one
   plugged into the model 80 I'm using now, with PC-NFS telnet.

   But NOTE: the model 80 is microchannel, the model 30 is ISA.  I have no
   idea whether the same mouse can go on the model 30's mouse port.

   Also, there are certain points where using Logitech's driver for that mouse
   makes the 80 miserably slow.  Notably when I am using Norton Commander, 
   and the commander wants to read the directories to be shown in the
   directory windows, it just sits there for a moment before it displays
   anything.  And this always starts immediately after I run Logitech's 
   MOUSE.COM .

   So now I use Microsoft's MOUSE instead, and it doesn't seem to have any
   problem.
