Old Jupiter went several weeks without a 918BB981 on startup, even
though the control panel battery needs replacing.
Then today, it threw one again, and even though all the drives spun up,
it wouldn't even go to DST.
I got out the socket wrench, and started reseating connectors. First,
the drives. Then, the books.
There's an old saying: you always find everything in the last place you
To that, I offer a corollary: if the problem is a dirty connector, it's
always the last one you reseat.
Just about the only one left to reseat was that short little flex-PC
cable with the honking big 96-pin connectors on it, connecting the main
board to the processor-side book-cage. The same kind as the one I'd bent
two pins, on, on the expansion side, and had to cannibalize from the
carcass of our 200.
The the same kind that I'm almost afraid to touch.
I VERY GINGERLY reseated the cage end of the cable, plugged the power
back in, and hit the start button.
It got past the point where it had 918BB981'd. The processor light
started flickering. The poll indicator on the terminal went on. It asked
me to sign on. DST indicated 3 good mirrored pairs. It had, of course,
forgotten the date and time, but that was to be expected with a dead
control panel battery and several unpluggings.
So now, I guess I'll go pick up another CR2450 coin battery. And the
small socket set that can actually get at the bolts that hold the book
