Of Mice and Memos.

     Our memo of the month award goes to the employee of an unnamed computer
company.  It went to ALL field engineers about a computer peripheral problem.
The author of the memo was quite serious.  The engineers rolled on the
floor.  Here goes.

     Mouse balls are now available as FRU (field replacement units).
Therefore, if a mouse failes to operate or should it perform erratically, it
may need a ball replacement.  Because of the delicate nature of this
procedure, replacement of mouse balls should only be attempted by properly
trained personnel.

     Before proceeding, determine the type of mouse balls by examining the
underside of the mouse.  Domestic balls will be larger and harder than
foreign balls.  Ball removal procedures differ depending upon the
manufacturer of the mouse.  Foreign balls can be replaced using the pop-off
method.  Domestic balls are replaced using the twist-off method.  Mouse 
balls are not usually static sensitive.  However, excessive handling can 
result in sudden discharge.   Upon completion of ball replacement, the 
mouse may be used immediately.

     It is recommended that each replacer have a pair of spare balls for
maintaining optimum customer satisfaction.  Any customer missing his balls
should suspect local personnel of removing these necessary items.

Thank you.
