Sun Type 4 keyboard failures

[bennett at beach.cis.ufl.edu]

Has anyone been experiencing failures with the type 4 SUN keyboards?  So
far this week alone, I have had two failures.  Both involved the "RIGHT
SHIFT" key not working.  I have also noticed the springs tend to pop lose
beneath the key cap.  These two failures are out of 13 SUN 3/80's
installed in an undergraduate lab.  About six weeks ago I had an identical
failure on another machine.  None of these machines is much more than six
months old.
