The source codes of the legendary “Makovsky” graphic editor MacPaint and QuickDraw libraries are transferred to the Museum of Computer History
as “samples of great software and hardware design”.
Graphic editor with libraries worked on 128 KB of RAM and 8 MHz processor.
The source code is still the copyright of Apple and can only be used for non-commercial purposes.
MacPaint and QuickDraw were written by Bill Atkinson, who was part of the original team for creating Macintosh computers (in the photo to the right).
The MacPaint graphics editor was based on a previous development called LisaSketch (also known as SketchPad) for the unwelcome success of the Apple Lisa computer. Work on the program was completed in October 1983.MacPaint 1.3 sources
: 5822 lines on Apple Pascal plus 3582 lines in assembly language for the Motorola 68000 processor.QuickDraw library sources
in 36 files in assembly language for 68000.
In general, in this regard, an interesting question arises: maybe it makes sense to oblige all software developers to open source codes for their outdated programs? Someday they may come in handy for backward compatibility.
