Differences between 3032and 3032B ROMs?

In my ongoing debugging of Zork for the PET, I observed some
interesting behavior: selecting 3032B vs 3032 (graphic keyboard)
in VICE made a difference in, apparently, positioning the cursor for
the initial prompt and the status line.  It suggests to me that
the zero page usage is different between the two keyboard layouts.
I didn't think that was so.

My question is, can any one shed some light on the basic sorts
of differences between the editor ROMs for a graphic keyboard
and a business keyboard?  Before this experience, I was thinking
that only the keycode table was different.

Yes, I plan to go through the ROMs with a fine-toothed comb.  I'm
interested in any tips to help me narrow the search.
