Minimum client expectations, LTSP Triage

  "Certainly, within some small spaces, we may be able to optimize  
things, but the
   bottom line is, that old 486 with 16 megs of memory simply isn't  
going to work
   as a thin client any more."

Of course an old 486 with 16 m ram will work as a thin client!! you  
can always use it as a telnet terminal or install a distro that is  
suitable for this architecture.
Even now my toaster is running as a thin client, just joking :)
