I have tried this with miss-matched supervisors and they have to be
identical for the SUPERVISOR SYCRONIZATION to occur. Identical
including the existance or non-existatnce of NFFC. If they are not only
one comes on line meaning no extra MSSF either. I had a buch of them
and tried several combos. THis was my experience.
