   If there was, I would have mentioned it. Also, people would have
used that functionality in many things. On the Apple II line, that
font is in a Chargen (Character Generator) ROM that's connected only
to the graphics output logic. There is no way to read out the font
with a PEEK, let alone change it.

   On the Apple III, apparently the font was mutable and stored in
RAM.  Along with other neat stuff like per-character foreground &
background colors. Of course, does that logic ever make it out to the
Apple II? Not if Apple's going to release the //e as a ][+ with
lowercase and an 80-column slot and just about nothing more. Being
able to bankswitch in the characters would have been nice (or some
other program-transparent hack for backwards compatability).
