Greetings Net People;

I work in a lab which is great need of a new machine.  First, I'll tell
you what we do, and then I'll drop some questions.

The lab is for vision/cognition research.  It has a bunch o' macs, 
including II, IIx, pluses and cx.  The work I do requires colour
graphics (speed is important), floating point calculations, and
specific timing.

We have a national instruments A-D board which migrates from machine
to machine.  We hook buttons for RT timing and an eye movement monitor
for sampling to it.

So, we need a new machine.  I suggested the IIsi because of 20MHz clock
and built in video.  I gather this is 8 bit video?  I hear that it uses
main memory for video.  Can you put in video ram?

Also, the national instruments board is NuBus.  I understand I need
an adapter which joyously comes with an FPU.  Can I get any more
slots than just 1 via an expansion box?  If so, how much, from whom....

Suggestions appreciated.  THanks.
