Folks:

This may seem like an esoteric problem, but it's very real when you
MUST solve it.  I'm running TeX on a NeXT, which is a PostScript machine.
For a book I'm doing, I need to use PostScript versions of the CM fonts;
bitmapped versions are unacceptable.  Fortunately, Blue Sky Research
sells Type 1 versions of the CM fonts, 75 in all.  I've bought them and
installed them.  Everything seemed to go smoothly until I tried printing
the quadratic equation.  That is, I used the simple Plain TeX expression:

	$$-b\pm\sqrt{b^2-4ac}\over 2a$$

Curiously, all elements appeared to be correct, except the minus and
plusminus signs were missing.  I've tried several other equations with
integral signs, matrix brackets, greek characters, etc., and I get
mixed results.  For example, theta is missing, while alpha and phi are
correct.  Also, the multiply "x" and left arrow don't appear.  Any 
thoughts on what might be amiss?  Seems like an encoding problem, but
I wouldn't know where to look.  Since this problem is not likely to be
of widespread interest, please reply directly to me at rlp@lanl.gov.
Thanks,

	Dick Phillips
