Unlukily I can't open my Racals now to check how many jumpers
are present on the GPIB board, because they are running.
I have electronic copies of both the standard and military 
manuals. They are different revisions than yours, as the page
numbers do not match. Anyway on both manuals only one jumper 
is shown on the GPIB board, and both state "install item 41 
on lower row of pins". Go understand.

Let's wait for the Bill's follow up.

Thanks,
Antonio I8IOV
