Oh!  Those might work better than my 10W.  Those must be BIG.

However...

Those are neat!  Have to find it Canadian or digikey though to be
useful, I don't like getting fee-p0wned by the courier companies on US
stuff.

But, doesn't matter (probably) as I just dug out an AT PS that
claims .4A min on 12V!  Yay!  That should be no problem to handle.

Funny, but only 2 out of about 15 AT PS's I have show a minimum load at
all, the rest just list max.  And only some tell me what color is what
V (though I could infer based on the std AT power connector location,
or use a DMM).  It looks like the older I go back, the more info they
give me.  No one cares about hobbyists anymore!

The one I'm going to use is from '96.  (Would you believe I have a few
from the 80's!)

Back to soldering...
