[R-390] R-390A hard to find clamps

[Richard]

Hello OM,

At one point I found the clamps to be more and more difficult to 
find.    One of the mechanical engineers at work suggested Small Parts 
Inc.  (http://www.smallparts.com/).    They have over 300 types of  
clamp-on collars alone.  I even found some small plastic bearings I used 
to repair the card reader in my HP-65 calculator.   Well recommended.
