Computer History Museum Releases Photoshop Source Code
The Computer History Museum on February 13, 2013 released the 1990 Photoshop 1.0.1 source code for non-commercial use with Adobe's permission. The archive contains 179 files (about 128,000 lines), primarily Pascal and Motorola 68000 assembly, and includes Grady Booch commentary highlighting early architecture such as tiles, filters, and virtual-memory abstractions useful for studying legacy I/O and file-format handling.
