Not as simple as that - you'd just have an analogue frequency meter
showing the instruction rate.
Right, which is what I interpreted the original poster to mean.
Was that not what he meant?
The old GE
machines with the "Thousands of Operations Per
Second" analogue meters were kind of neat too.
So just how does one construct
such a meter? If you wanted it to show how busy the machine is,
something in the
idle loop toggle the bit that drives the integrator. Set the bit
high when you come out of the idle loop, set it low when you go in...
That'd work very nicely for a load indicator.
