IJMC - Mouse Balls

This one is a classic. Some of you may have seen it far too many times, 
to you I apologize. However, many more have likely heard about "mouse 
ball" jokes with no idea from where they stem. So here it is, the 
original IBM Field Engineer alert, years old at this point. Use with 
caution.							  -dave



Mouse Balls (R)

(Thanks to Mate Gross and dhingle@newgen.nexgen.com)

This is an actual alert to IBM Field Engineers that went out to
all IBM Branch Offices.  The person who wrote it was very serious
but the rest thought it was pretty funny.

    Abstract:  Mouse Balls Available as FRU (Field Replacement Unit)

    Mouse balls are now available as FRU.  Therefore, if a mouse
    fails 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
    depending upon 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 statisfaction, and that any
    customer missing his balls should suspect local personnel of
    removing these necessary items.

    To reorder, specify one of the following:
    P/N 33F8462 - Domestic Mouse Balls
    P/N 338F461 - Foreign Mouse Balls
