Which is of course right on the button. I have to say, there's very 
little way I could justify the use of kWh on either of the two 
projects, if the alternative is having the machine off. But for 
people wanting to do something with their classics, I assume the 
electricity has proven not to be a major consideration. And certainly 
for any already-running and on-line VAXen, that must be the case.

Something I hadn't considered, though, is whether classic hardware 
burns less current "idle". I knew about sleep mode on my G4 laptop 
using less power; at what generation did that become prevalent?

The cryptography and Optimal Golomb Ruler projects *should* be 
integer, but I don't know how the algorithms are implemented.
