Also, what is
the story on the FCO on the power harnesses for the
backplane? The two harnesses in
my BA123 are made of a gray ribbon cable pressed
into orange
connectors.
I *thought* it was the early BA23 power harness that
had the issue, not the BA123. A bit of googling through
newsgroups (comp.sys.dec or comp.os.vms) should nail
that down somewhat.

Yes, with the BA23 there were serious risks of fire

that with the _OLD_ power harness. You can recognize those by
the color: the power wires are WHITE with colored plugs. The NEW
ones have COLORED wires with a WHITE plug. If you have a BA23
with WHITE power wires... burn it!
Won't it do that by itself? Also, I'd recommend not burning the whole
BA23 enclosure, but rather only the power harness. And assuming one
couldn't find a replacement power harness for the bad one, what would it
take to modify/repair the bad one to make it safe to use? Is it just
the matter of replacing some of the existing wire with something of a
heavier gauge?

Anyone know what the official DEC conclusion was?
