What if I took an older 5V CPU (say... an 80486) and
wired 'er up to just
Vcc & Ground - how much power would that use? [[ I've started some google
searches & I will continue, but I was hoping others here would
have better
ideas than my lame-azz neurons & google so far ]]
1st, I assume that you won't leave any input pins "floating" - if you
do the
results are somewhat unpredictable (from no effect to more than "somewhat
glowing"!*)
* I had one dx4 overdrive chip self-destruct with one tiny (about 0.1"
square) part of
it glowing white hot ... never did find out why :-(
2nd, If unclocked the results are also difficult to predict - but the
probability is
that the consumption will be very low indeed (just as overclocking increases
power
usage).
