As I understand it, the si video is like the ci.  It shares RAM.  Apparently 
the video can access the 1 meg onboard while the cpu is accessing the SIMM
memory.  I'm not a tech, but this is supposed to slow the machine down in 
some cases.

Just a note: I went for a job with Wolfram not too long ago. Didn't get it but
found out at one point that they can't stand the ci video. They say that in
8 bits they get a 25% _decrease_ in performance, down to mac II, so they just
put NuBus video cards in. It's only an advantage in 1 or 2 bit mode, no
difference in 4.
