Check Out the Source Code For the Xerox Alto

Posted by samzenpus on from the take-a-look dept.

jfruh writes The Xerox Alto is a computer legend: it was never sold to the public, but its window-based OS was the inspiration for both the original Mac operating system and Windows. Now you can check out its source code, along with code for CP/M, a similarly old school (though not graphical) operating system.

  1. CP/M source code by NoNonAlphaCharsHere · · Score: 3, Insightful

    In honor of CP/M's 40th birthday, the [PL/M] source code for a very early version from 1975, and three later versions from 1976, 1978 and 1979 are being made available for non-commercial use.

    LOL -- and a bit of Digital Research cluelessness from the past as well.

    Oh, get over yourself. CP/M was 1975 for god's sake. In the same time period (and until substantially later), Unix filenames were limited to 14 characters. A diskette held 243 kB. Unix and CP/M didn't hold back anybody, you idiot. They opened the way.

    BTW, people who use spaces in filenames are imbeciles. They don't have a clue how command lines operate. Point and click is about the limit of their brainpower.

    What did YOU give the world in 1975?
