A Technical History of Apple's Operating Systems
An anonymous reader writes "As part of his 1680-page book Mac OS X Internals: A Systems Approach, Amit Singh of kernelthread.com wrote a very detailed technical history of Apple's operating systems. Since he had to cut down on the history chapter because of the book's already too-large size, most of this chapter didn't make it to the printed book. Singh has made available the history chapter as a free PDF. The file is 140 pages long, and is generously filled with figures and screenshots. It starts with the internals of the original Apple I and goes through a tour of all operating systems Apple dabbled with, including internals of A/UX, Lisa OS, and such. It even covers details of outside influences like the Xerox Alto, STAR System, Smalltalk, and Sketchpad, and closer to home things like Mach, NeXTStep, and OpenStep."
(damn Slash indentation destroyer) but I think they renormalised it.
It looks like a great chapter, I am going to print it out then go to my favorite cafe, Black Dog, to peruse it. I think that counts as work hours. Much thanks to Mr. Singh for providing the PDF to Slashdotters and the web community.
