  Indigos need special Indigo mice. Replacement mechanical or optical
  (take note, mechanical mice haters!) mice are available from SGI or
  directly from Mouse Systems (510-656-1117).

  Indigo2s can use PS/2 mice as per the pcmouse(7) manpage. Dave Yost
  expands on this:  The Indigo2 takes any industry standard mouse of
  the variety variously known as "IBM PS/2", "Mouse Port" or "6-pin".
  A PC serial mouse won't do, even with an adaptor, unless it is
  claimed to work on a PS/2 through an adaptor.  The Logitech "MouseMan
  Cordless" mouse works for me.
