All archives are full commercial versions with no need for a serial
code. They will ask for name/organization/code, but you can type in
anything.

PDN_96.2.toast_.zip \- this is a TOAST4/MacZip image of the Pictorius
PDN CD 96.2, the latest that I have located. It contains Prograph CPX
1.4 along with a wealth of source code, demos, and archives of useful
files from older PDN releases.

PDN_96.1.toast_.zip \- this is a TOAST4/MacZip image of the Pictorius
PDN CD 96.1. Uploaded for historical purposes, this CD has earlier
versions of the apps and source code and may have 3rd party
samples/tools not on PDN 96.2.

Prograph_CPX_1.2_dc42.sit \- this StuffIt archive contains six disk
images in Disk Copy 4.2 format. This is the floppy distribution of the
commercial 1.2 release. The CD image above has far more documentation
and source code. It seems like Pictorius would trim electronic
documentation whenever they needed to fit a distribution on floppy
disks, probably because the disks shipped with printed manuals, so
this archive will be difficult to use unless you at least get the docs
from the CD image.

Overview
Prograph was a visual, object orientated, dataflow driven programming
language available on Mac OS in the 1980's and 1990's. You can read
more about it on Wikipedia: <https://en.wikipedia.org/wiki/Prograph>

Prograph was not a text language labeled "visual" just because it had
a GUI IDE. It was an iconic dataflow language. You would literally
draw your code. Unlike other flowchart developer tools of the time it
was a real, expressive language. You could open any computer science
book and implement the algorithms in Prograph.

Prograph CPX could compile 68K and PowerPC apps for Mac OS classic.
For a time, thanks to support from the Prograph community, it could
also compile Carbon apps for Mac OS X. Unfortunately a change in OS X
conflicted with the code produced by the PowerPC compiler bringing an
end to Prograph on OS X. In the near future I'll collect and upload
the Carbon related code for historical purposes.

Note: Another, completely new version of the language was implemented
by Andescotia Software at:
<http://www.andescotia.com/products/marten/> That version is currently
freeware. Since that site is still up and running I won't upload it
here.

Compatibility
Architecture: 68k PPC

IDE and 68K Compiler
* 68020 or higher processor.
* Minimum of 8 MB of free RAM.
* System 7 or higher.
* The IDE appears to run fine in SheepShaver, but I have not compiled
any apps there.

PowerPC Compiler
* A Power Mac.
* A third party linker. The Prograph PPC compiler did not perform the
final step of linking the files and building a Power Mac binary.
CodeWarrior works best for this. You don't have to write any C++, you
just have to create a CodeWarrior project, add the files, and build.
