Thanks to all who replied to my plea for help.  Barry Smith of Blue Sky
Research called within an hour of my posting and talked me through a
potential solution. The evidence seemed to indicate that many characters
were missing, both from the font encoding vectors and the *.afm files,
in the first 32 positions.  Not included in my posting was the fact that
I bought the Macintosh version of the CM fonts and used Altsys'
Metamorphosis Pro to convert them for use on the NeXT.  While I have had
no trouble with that program in the past, it apparently can not deal with
TeX encodings properly.  I have just reinstalled the CM fonts, starting
from MS DOS versions (thanks again to Barry Smith) and everything works
perfectly.  Thanks again,
