I realise that I'm not going to be able to keep these machines
running for much longer, but I'll keep trying for as long as I can.

..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

Done the math many times :-)

These little machines take about 30W max, are only used for an average of an hour a day. As for running costs? Peanuts. Heat output? Barely noticable.

My main laptop is slightly newer and about 10x the power. I have other systems, but nothing modern - I don't have the funds to get anything newer.

Besides, it's a fun challenge to keep the old ones running. I enjoy it :)
