Molecular Display Programs for RISC 6000?

    Does anyone know of cheap or free molecular display programs for the
 IBM RISC 6000 machines for academic use?  I'm thinking of programs like
 MIDAS or MMS of PCMODEL, etc., etc.  I'm also interested in displaying
 ouput, trajectories, etc. from the academic version of CHARMm.
