  It's not just the terminals. You find the same thing on HP 64000 LDSs and
9845 and 9835 calculators that use CRTs. I've never figured out why some do
it and some don't. I've bought stuff that's sat in un-air conditioned
storage with PLENTY of humidity here in Florida and it will be fine but
others that were stored under better conditions are full of spots. In fact,
the three 2648s that I just bought all came from the same place and were
stored under IDEAL conditions and one is almost completely covered in spots
but the others are perfect and have NO spots. I wonder if something
happened to some of them during manuacturering? I've seen a number of HP
voyageur series (HP-11C, 15C, etc) calculators that had never been
previously opened but had distinct spots of corrosion on the circuit board.
It appeared that someone had dripped sweat on them as they were being
assembled.

  I guess I should start picking up any HP CRT devices that have good CRTs
and save them just for the CRTs.
