Quite possibly.  You should be able to tell if this is so by looking at
words that have capitals in them, like the first word in each sentence. 
However, the vast majority of II+ software did not use lower-case letters. 
If you have the DOS 3.3 Master, =everything= on that disk is all caps.

You need a new character chip, commonly called a lower-case ROM.  If your
II+ does not have jumper blocks on the rows of RAM then the mod is a simple
one of swapping out one chip.  I don't know of anyone who sells these chips
any more.

Dont' work at ALL, or don't display right on the screen?  I assume that
they don't work at all, since you said you can't do a CATALOG.  Odds are
pretty good that it's a bad keyboard if those are the only 4 letters that
give you trouble.
