    The "original" IRIS Indigos do have a battery on the CPU board;
some of the dratted things are soldered down (*that* design "engineer"
needs a whack with a clue-by-four), but some, even some of the (later,
I'm guessing) R4000 chipped machines have the batteries socketed.

    If I had one of the ones with a soldered-down battery, I'd work
up an "ECO" to install a battery holder someplace and wire that to
the old solder-down point.

    If you can find that, please post it.  I'm sure somebody will
find it handy someday!
