Does anyone know what CPU that fits in the SPARC 20 uses the least
power? Does that significantly effect power consumption from the mains
supply? I'm looking to run an SS20 for a task that will require
minimal CPU restorces, yet will need to be on 24/7. For obvious
reasons I don't want it using loads of power. At the minute I have two
machines configured (which we just taken from the top of a pile of 5
SS20's I have) both of which have dual CPUs in them - one 2x75, the
other 2x125. Clearly that's not an ideal solution, but was wondering
about the other CPUs. I have an SM61 somewhere hear. Is there anything
likely to use significantly less power than that, or would I be saving
myself next to nothing by using another CPU. I don't want to spend $$
on a CPU and carriage if it won't bring any significant benefits.

I don't think the CPU will have a non-negligible effect on the
total power consumption, but I guess if you want to minimise it,
go for a low speed CPU with no E$. But I suspect we're talking
less than 1W difference...

I suspect that the consumption of a CPU will be considerably
less than the disk(s) installed on the SS20, especially if they're
older drives.
