If it's that close that it's safe to connect to a PC, you could 
determine the scancodes by running "showkey -s" under linux. It might be 
something like "Set 3" which is what SGIs used to use (and documented in 
their manpages).

And I found a page somewhere (sorry, forgot where) that mentioned using 
a Logitech Trackman on a RC2030 which worked "99% of the time" so a 
fairly common mouse might work.  Most of the Logitech mice I've seen 
like the one in the picture Al found, were quadrature mice (X+, X-, Y+, 
Y- and 2/3 button signals) but presumably there were serial mice in that 
style too.
