Intel with the help of Ted Hoff introduced the first microprocessor, the Intel 4004 on November 15, 1971. The 4004 had 2,300 transistors, performed 60,000 OPS (operations per second), addressed 640 bytes of memory, and cost $200.00. Intel also introduced the 4-bit bus.

First edition of Unix released on November 03, 1971. The first edition of the "Unix PROGRAMMER'S MANUAL by Ken Thompson and Dennis M. Ritchie."
