The Amiga, which replaced a computer the size of a refrigerator, was set up to control heat and air conditioning at the district’s 19 schools. It has been doing that job tirelessly for the last 30 years.

30 years! I suspect it's like a light bulb that runs for years if left on.

 

its got a little bit for every air conditioner, and it switches em on and off. sounds like the amiga is too good for that job already.
you might as well leave it to a gameboy, but even a gameboy would be too good.

A custom little cheapo lcd game could pretty much surfice if it was wired up right.
But I suppose, thats why you learn all this stuff, cause simple machines are useful.
