I think the problem (unfortunately) is the 32BitQuickDraw init.  The routines i
n it take up much more processor time in order to handle the expanded color
requirements.  I have an se/30 and Solarian is very slow (it jerks, shakes, and
does a few dances) with the 32BQD installed, even if it is set at 256 colors.
Taking it out of the system folder and restarting usually takes care of this.
The only problem is that the Si's have the video built into them.  I haven't tr
ied my solution with an Si, but I have a feeling that it might not work.
  Your suggestion that the absence of a math coprocessor may also be a problem
depends on whether Solarian uses one and how heavily.  Since, until recently,
every color mac has had a math unit (i think) B.H. may have relied on one being
available.
            In other words... no answers, just a few suggestions to try and
 and a few more questions.


                           Good Luck,
