NM,
I don't know anything about the sim that you are referring to however I do know that the FMS in an F-100 is of the airbus style. Newer airbuses although similar in design, have a much newer and more intuitive software version. If you can however find manuals or sims for slightly older generation airbus products (A300, A310) it should be spot on.
This may be a start for you.

Good luck!
