Those are most definitely wasp nests, a particular variety we here at least
call "Mud Daubers".
The "nest" varies in appearance from a series of tubes, to a simple mass
with a hole or two in it.
They are made from mud, and will come apart when wet. However, they are
unusually hard mud, almost cement-like! The way they are normally removed on
buildings & such is whacking them with a board or hammer. In your case, it's
very likely to take components off the board if you do that. My suggestion
would be to moisten the mud with water, which it will soak up. Moisten
again... keep repeating, till the whole thing softens. I'm just guessing if
this would be the best way to remove. Of course, be very sure there are no
live wasps in side it! Be aware they may also be live larvae inside the mud
nest too.

Subject: Bugs in computer hardware (real ones)
I have a dual floppy system from Computer Automation
that
some kind of insect had made a nest in a long time ago. I'm not sure how
to remove the stuff. I tried water but it has no effect. It's hard as
concrete! I can chip it but it takes quite a bit of force and I don't want
to rip off any components under it. Any ideas? Here's some photos:
