SuperGraph differs from [Apple?s Graphing Calculator][1] in its
flexibility and customizability when dealing with implicit expressions
(which Graphing Calculator does not directly support) and in its
ability to run on 680x0 (non-PowerPC) Macintosh computers.

SuperGraph is especially suited to demonstrating various implicit
expressions and techniques of sketching them in a classroom situation.

DL #1 SuperGraph v1.0 FAT

Compatibility
Architecture: 68k

SuperGraph requires a Macintosh with System 6.0.4 or higher, a 68020
or higher processor and a math coprocessor (or PowerPC). SuperGraph is
accelerated for Power Macintosh and ships as a ?fat binary?
application. 32-Bit QuickDraw is also required, as is a color or
grayscale monitor. At least 16 grays or 256 colors should be used; 256
grays or millions of colors produce the best-looking implicit graphs.
(Images that are copied or saved will be of the same quality no matter
what the screen can display.) Saving pictures to disk is not available
under System 6; System 6 users should use copy and paste instead.
Users of 68040 Macintoshes without math coprocessors (some Performas,
some PowerBooks and certain other models). Unfortunately, no version
is available for 68020 and 68030 Macintoshes without math coprocessors
(LC series and some Performas and PowerBooks).
