But full credit goes to the company where Mr. Taylor worked after leaving ARPA: Xerox. It was at the Xerox PARC labs in Silicon Valley in the 1970s that the Ethernet was developed to link different computer networks. Researchers there also developed the first personal computer (the Xerox Alto) and the graphical user interface that still drives computer usage today.

This is my understanding of it. I've know about this from other sources for decades.

As a 20 year PARC vet I can attest to that. With Bill Gunning, I am personally responsible for 10-base-T ethernet and laser mice (solo).

I, for one, welcome our new Cybernetic Overlords /.

The missed opportunities of Xerox PARC is staggering.

Its like:

“Watson, come here. I need you”
“Yes, Dr. Bell?”
“Go sell these two instruments”

Let not forget Datapoint corporation which
produced the Datapoint 2200 programmable
microprocessor in the form of a PC in 1970.

It included a complete Disk Operating System in 1972.

Aside from being one of the first personal computers, the Datapoint 2200 has another connection to computer history. Its original design called for a single-chip 8-bit microprocessor for the CPU, rather than a conventional processor built from discrete TTL modules. In 1969, CTC contracted two companies, Intel and Texas Instruments, to make the chip. TI was unable to make a reliable part and dropped out. Intel was unable to make CTC's deadline. Intel and CTC renegotiated their contract, ending up with CTC keeping its money and Intel keeping the eventually completed processor.[2]

CTC released the Datapoint 2200 using about 100 discrete TTL components (SSI/MSI chips) instead of a microprocessor, while Intel's single-chip design, eventually designated the Intel 8008, was finally released in April 1972.[3] The 8008's seminal importance lies in its becoming the ancestor of Intel's other 8-bit CPUs, which were followed by their assembly language compatible 16-bit CPU's—the first members of the x86-family, as the instruction set was later to be known. Thus, CTC's engineers may be said to have fathered the world's most commonly used and emulated instruction set architecture from the mid-1980s to date.

Equally significant is the fact that the terminal's multi-chip CPU (processor) became the embryo of the x86 architecture upon which the original IBM PC and its descendants are based.

I agree. Xerox PARC came up first with the concept on local area network. Xerox PARC also invented mouse, touch screen, GUI, etc...
