Pointer to Pointer is a double pointer, denoted by (**). Pointer stores the address of the variable and pointer to pointer stores the address of a pointer variable and syntax can be given as int **ptr2ptr;
When a variable is declared as being a pointer to type void it is known as a generic pointer. Since you cannot have a variable of type void, the pointer will not point to any data and therefore cannot be dereferenced. It is still a pointer though, to use it you just have to cast it to another kind of pointer first. Hence the term Generic pointer.

On 289, the pointer was a round peg, with a rib on the top, which was a part of the cast aluminum cover. The 302 went to a separate sheet metal pointer. If you can't see the pointer, it is either broken off or you have a 302 cover on your 289; they are interchangeable.
