microprocessor 4004: -2,300 transistors -10 µm features -10 mm2 die -108 kHz kHz  1974... Intel releases its 2MHz 8080 chip, an 8bit microprocessor. It can access 64KB of memory. It uses 6000 transistors, based on 6micron technology. Speed is 0.64 MIPS. In a desperate act to save his failing calculator company, MITS company owner Ed Roberts begins building a small computer based on Intel's new 8080 chip, with plans to sell it for the unheardof price of US$500. MITS completes the first prototype Altair 8800 microcomputer. Bravo is developed for the Xerox Alto computer. It is the first WYSIWYG program for a personal computer.  1975 Bill Gates and Paul Allen found MicroSoft (the hyphen is later dropped). MOS Technology announces the MC6501 at US$20 and the MC6502 at US$25. At this point, the Intel 8080 costs about US$150.
