This memo is from an unnamed computer company. It went to all field
engineers about a computer peripheral problem. The author
of this memo was quite serious. The engineers rolled on the floor!
Memo -
Mouse balls are now available as FRU (Field Replacement Unit).
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
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 by using the twist-off method.
Mouse balls are not usually static-sensitive. However, excessive,
upon completion of ball removal, 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."
