First thanks for all replied replied:

   - ROSS's hyperSPARC chip will work on Solaris 1.1 (SunOS 4.1.3) with a ROSS patch.

   - The improved speed increase with SS20 model 61 with the 150Mhz (512Kb cache)
        module can be twice as much.

   - There may be a down fall installing the chip on a RDBMS machine, since the
        chip has only 512KB cache over the 1MB of the SuperSPARC, but on the other
        hand performace increase can be great with floating point work.

   - I will be going ahead with the evaluation and I will summaries my results
        when it is over.

   - Also, the UK dealer which I am dealing with is:
        Stellar Performance
        Oxford House
        London W4 4DH
