Pioneer Saturn (aka Pioneer 11) Encounter Trajectory - Question.

Does anyone here know where I can find information on Pioneer 11's
trajectory during it's 1979 encounter with Saturn? I have looked for
diagrams on the internet, but so far to no avail. Ideally, I would
like to locate something similar to this NASA/AMES drawing of
Pioneer's Jupiter flyby:

Also, I am trying to find a software program that simulates the
journeys of both Pioneer 10 and 11 through the Solar System. I own
copies of 'Redshift 2' and 'Redshift 3', but neither program features
these particular probes (a big omission, IMHO).

Any help on this matter would be appreciated,

Ian Regan.
