..do the math on power, maintenance etc cost on keeping the old 
junk running vs doing it e.g in a virtual machine on a newer host 
iron, you may find that the newer iron adds academic profits such 
as learning to run virtual machines.

..then again, in some climates, you _may_ have a use for the 
100W or 300W or so of waste heat generated by that old iron.

..waste heat value: Say 150W @ .5NOK/kWh and per year?  
arnt@celsius:~$ qalc 150W*1year*.5NOK/kWh to $ 
warning: It has been more than one week since the exchange 
rates last were updated. 
(150 * watt * (1 * year) * (0.5 * NOK)) / (kilowatt * hour) 
= approx. $110.73655
