• The first microprocessor was developed by what was then a small company called Intel in the early 1970s

9. Market the chipset as a "general purpose" microprocessing system for use in applications where digital logic chips would have been used. The chipset was a success and within a short while Intel developed a

10. general purpose 4 bit microprocessor called the 4004. 11. Historical review

In 1974 the more powerful second generation microprocessor (the 8008) was announced fabricated as a single chip.

12. Quickly followed by the Intel 8080. 13. Both the 8008 and the 8080 operated from a single +5v power supply (using NMOS 14. technology). 15. Historical review
