Nope; the C64 had special character-graphics hardware which was used for
games. When the Apple II was designed Woz used a canned character generator
ROM (the 2513) which was a part used by dumb terminals. Later Apple would
use 2532 ROMs and 2732 EPROMs instead, but no logic was ever added to let
you reprogram the character set. Hi-res was used instead.
