I wonder if anyone have brought this up before. I didn't search the
group since there are many results regarding diff eq that has to do
with other topics which would be too much to read through.

On the 49G, 49G+, 50G in the Diff Eq window settings input form, at
the independent var initial and final value fields, the help text
shows something else about z-view volume values, which to me doesn't
seem to have anything to do with graphing differential equations;
wondering if there are any other interpretations. It's minor, at least
the field functionalities are right, but this made it a little
confusing in learning about graphing differential equations and doing
it on the calculator. The manual got it right though.

Regardless, I was able to graph the diff eq and superimpose the
slopefield plot to match what the 89 gives. Pretty impressive
considering this feature was available on the 48G back then out of the
box.
