As described at the time, the contemporary Sinclair Z88 had a separate bit of management logic that kept the Z80 CPU asleep until there was some interaction, in order to get ludicrous runtimes on 4xAA. (I wouldn't be surprised if the Model 100 did similarly, but there was no point in doing it on machines that plugged into the wall...)

A few things would need hacks like cursor blink (don't do it) and updating displays like clocks (wake every minute?). Interesting.
