CP/M

To round out the early days of the microcomputer revolution, we need to introduce a Seattle native and student of the University of Washington.

Enter Gary Kindall, computer science graduate of 1972. At this time, the pair who founded Micro Soft was working part-time in the university district of Seattle.

Gary, like Paul & Bill had a love for the DEC computer. After completing a tour for the Navy, Gary founded the company Intergalactic Digital Research.

One of his projects was to write an operating system for microcomputers called the Control Program Microcomputer (CP/M). Gary incorporated features he liked from the DEC operating system to the Control Program Microcomputer.

Because CPU designs need to be bonded to an operating system, Gary wrote a second operating system specifically for the Intel Microprocessor, calling it Programming Language for Microcomputers PL/M.
