In my original copy of the 1992 manual, there is only one jumper 
indicated on the GPIB board.  It is at the front of the board.  Pages 
7-34 and 7-35 show it.  On the first page it says : "Make certain the 
jumper plug is installed in the upper two pins of SK4 as shown".

On the next page however it says the opposite:  "Install item 41 (i.e. 
the jumper) on the lower row of pins".

One can only assume that these are for the two versions of the language, 
though it would be nice to have it explained a bit better! 

Good luck!
