Via Richard Davey comes news that the original Amiga source code to DeluxePaint is on GitHub.
Adafruit looked on GitHub and indeed found the files posted here with this explanation:
DeluxePaint/DPaint original 1986 amiga source code; Includes manual book and reference card pdfs for DPaint 1
Starting point – PRISM.C is where you can find main()
Note – This source code has been released in 2015, and I’ve just made a complete package here on Github.
I’m not allowed to pre-compile the software for you, as I’m not licensed to distribute the Software. They never said anything about not distributing the source code however, not to mention that at the time of creating this repo the original website wasn’t available, so I wanted to make sure the source was saved.
Also note that the LICENSE file doesn’t contain a regular GPL or BSD license, but a custom one – you’re not allowed to redistribute the compiled software.
The license is the Computer History Museum Software License Agreement.
A look at the museum website turns up a 2015 article about the software, as the code, manual and reference card are in their collection.
Dan Silva created DeluxePaint in 1985 at Electronic Arts, a then 3-year-old publisher of computer games. The initial goal was to write an internal graphics design program, called “Prism”, for creating game artwork at EA. But it quickly became clear that it was a general-purpose design tool that might have broad appeal outside of EA.
The first version of what became called DeluxePaint was released at the same time as the Amiga at the end of 1985 at an introductory price of $79.95, and was sold later for $99.95.
The source code
With the permission of Electronic Arts, Inc. the Computer History Museum posts, for non-commercial use, the source code to the 1986 version I of DeluxePaint. You have to click through the license agreement mentioned earlier to download a zip file with the code. There are 89 files of C language source, comprising almost 17,000 lines of code in about 474 KB of text.
See the Computer History Museum article for more details.
