This patent wasn't accepted by Japan so Japanese businesses could avoid paying any fees, but in 1989 – after a 30-year legal battle – Japan granted the patent; so all Japanese companies paid fees up until the year 2001 – long after the patent became obsolete in the rest of the World.

It was the first functional prototype of a computer scaled down to be optimized and priced for the individual user (about $43,600 - equivalent to $368,500 in 2019). Used for the first time at the National Institutes of Mental Health in Bethesda, Maryland in 1963, many consider it to be the first personal computer, despite the big dimension of some elements, e.g. the memory rack.|

|1964||USA||Computers built between 1964 and 1972 are often regarded as "third-generation" computers; they are based on the first integrated circuits – creating even smaller machines. Typical of such machines were the HP 2116A and Data General Nova.|
|1964||USA||Programming language PL/I released by IBM.|
|1964||USA||Launch of IBM System/360 – the first series of compatible computers, reversing and stopping the evolution of separate "business" and "scientific" machine architectures; all models used the same basic instruction set architecture and register sizes, in theory allowing programs to be migrated to more or less powerful models as needs changed. The basic unit of memory, the "byte", was defined as 8 bits, with larger units such as "words" defined with sizes that were multiples of 8, with many consequences. Many competing computers at the time used word sizes that were multiples of 6. The marketing term "IBM Compatible" was often used, at this time, to indicate that the architecture used 8-bit bytes. Over 14,000 were shipped by 1968.|

|7 Apr 1969||USA||The first Request for Comments, RFC 1 published. The RFCs (network working group, Request For Comment) are a series of papers which are used to develop and define protocols for networking; originally the basis for ARPANET, there are now thousands of them applying to all aspects of the Internet. Collectively they document everything about the way the Internet and computers on it should behave, whether its TCP/IP networking or how email headers should be written there will be a set of RFCs describing it.|

Later developments include VLSI (Very Large Scale Integration) of integrated circuits 5 years later – typically 10,000 components. The fourth generation is generally viewed as running right up until the present, since although computing power has increased the basic technology has remained virtually the same.|
|1972||USA||Programming language C developed at The Bell Laboratories in the USA
Dennis Ritchie, one of the inventors of the Unix operating system, simplifies BCPL into a language he calls B, then iterates B into C. It is a very popular language, especially for systems programming – as it is flexible and fast. C was considered a refreshing change in the computing industry because it helped introduce structured programming. Inspired by C, C++, was introduced in the 1980s, and in turn helped usher in the era of object-oriented programming.

Unlike the 8080 it is sold not as much as a general-purpose "number cruncher / computer" CPU core but more as a control processor for industrial control and as a peripheral processor.|
|1974||USA||Engineers Chuck Peddle and Bill Mensch leave Motorola after completing work on the 6800 CPU and join MOS Technology, Inc.|

The 6501 is quickly withdrawn from sale and replaced with the 6502 which has a "lawsuit-compatible" design, but is otherwise nearly identical to the 6501. The 6502 becomes one of the most popular CPUs for the next 10 years and is used in many computers and game consoles (most notably the Atari 2600, Apple II, the Commodore PET, VIC-20 and Commodore 64, the Acorn Electron/BBC Microcomputer, and the Nintendo Entertainment System/NES).|
