Nope, fresh PRAM bat didn't work either, firing up the compressor next. FEH!

GAAAAAAK!!!!! No go, probable pooped-out PSU. xx(

Found a screw shorted between a cap can and standoff for the AirPort card that's likely been there for a very long time . . .

. . . also saw what looked like a loose clip for RFI shielding shift position from underneath the MoBo chassis plate to underneath the HDD chassis plate while vacating a quantity of dust small enough that it shouldn't have been the culprit.

Don't have the planned backup on hand for this as yet: Dualie 1.25MHz MDD/FW400

Haven't got the new PSU for the 466 DA yet either . . . :-/

. . . iLamp/800/X as main machine?
