“Charles Thacker, one of the lead hardware designers on the Xerox Alto, the first modern personal computer, died of a brief illness on Monday. He was 74.
The Alto, which was released in 1973 but was never a commercial success, was an incredibly influential machine. Ahead of its time, it boasted resizeable windows as part of its graphical user interface, along with a mouse, Ethernet, and numerous other technologies that didn’t become standard until years later. (Last year, Y Combinator acquired one and began restoring it.)”
