I am considering moving the development of a data
acquisition and display system from a PC/AT to a 
MAC II. I am currently reading my way through Inside
Macintosh (all 5 volumes) to get an idea of what the
programming environment will be like, but I have a few
questions that I would like to throw to the net. BTW, current
system is written in MSC 5.0, and is heavily number-crunching
and graphics oriented.
  1) I am considering Lightspeed C - is this a good choice?
  2) My current PC program uses the timer interrupt to
     initiate data collection from an A/D card. Would the
     environment be similar on a MAC II - how would I
     control data acq. timing?
  3) Does anyone have any experience with plugging in a
     68882 math coprocessor, rather than the 68881?
  4) I would like to display a rather primitive line
     drawing (maybe 20-30 line segments) and have it move
     after each data collection interval (maybe 30 times
     per second). Where can I find out how fast
     Quickdraw is at drawing line segments. Most of the
     available time will be spent computing, so the
     drawing itself must be fast.

 Thanks for any help you can offer.
