Xerox Alto Restoration CuriousMarc This video series chronicles the restoration of a seminal Xerox Alto computer. This is the machine that Steve Jobs saw during a visit at the famed Xerox PARC, and would inspire the Macintosh. Although never commercialized, this 1974 design, built entirely out of simple TTL logic before a powerful enough microprocessor even existed, was so far ahead of its time that it is hard to comprehend. It demonstrated many then unheard-of firsts, and astonishingly, they all made it to the present day computer, barely modified: a personal computer booting from a hard disk, with a graphical screen, proportional fonts, a mouse driven GUI, a WYSIWYG text editor, a drawing program, IDE with overlapping windows, Ethernet, Net booting, laser printing, the first optical mouse - and even network games. Follow along as we delve into the depth of this machine while bringing it back to life step by step, while being constantly amazed at its never ending cleverness. https://www.youtube.com/watch?v=XhIohWr10kU&list=PL-_93BVApb58I3ZV67LW3S_JEM...
