I took pictures of a monochrome mac screen several years ago.  The pictures
turned out crisp, but as with most computer screens, the lines were not
straight.  That is, you will pick up the slight bowing of the screen,
which I found annoying.  However, depending on how good the results need
to be, the bowing may not bother you.  (Try to avoid getting any of the
black border, and the bowing will probably be less obvious.)

About the film, use the slowest film you can tolerate.  Remember
that the screen has a refresh rate of approximately .016 seconds.
So, you want to at least allow enough time for the retrace to make one
full scan of the screen (so everything makes it onto your slide).  If
memory serves me correctly, the shutter speeds are in 1/X sec (where
X is 250, 1000, etc.).  So, you want your shutter to be open at least
1/30 sec.  

I don't know about what type of color film would be best.  (If no one
else can provide suggestions, I suggest calling Kodak's 800 number.
They have been very helpful in the past with special developing
situations I have found myself in.)
