Fantastic. 25 years after it was first written for the Mac, Apple has chosen donate the source code of MacPaint and QuickDraw to the Computer History Museum, making one of the earliest and most efficient pieces of art software ever available to public scrutiny for the first time ever.
Originally released back in 1984, MacPaint was a revolutionary piece of software that first introduced common image editing conventions like the lasso tool and the paint bucket. From a programming perspective, though, MacPaint is even more impressive: it was so efficiently programmed and its memory constraints were so tight that MacPaint actually revealed bugs in the underlying system that could only be exposed by running so close to the edge of available memory.
According to a whimsical Steve Jobs, up to twenty-four man years went into the writing of MacPaint. If you’re interested in taking a glimpse at coding perfection spread across 5,804 lines of Pascal and 2,738 of assembly, go take a look.
