With the permission of Abobe System, the Computer History Museum has made the source code for Photoshop version 1.0, the very first original Mac-version of Photoshop from 1990, available.
“We developed it originally for our own personal use…it was a lot a fun to do.” commented Thomas Knoll, a PhD student in computer vision at the University of Michigan, who is working with his brother John Knoll, at Industrial Light & Magic, on the project ‘Display’ (which was the program’s original name). Adobe acquired the licence for the program in 1988, 2 years before it was released to the public as "Photoshop", the name that has since become such an iconic application.
Check out the Computer History Museum website for plenty more historic trivia and comments on the source code by Grady Booch, a famous software architect.
A little something extra for the geeks among us…
The source code comprises about 128.000 lines of code within 179 files, most of which written in Pascal and the remainder in 68000 assembly language. You can download the original user guide/manual and have a read through a tutorial here!
