The first ( retroactively ) RISC-labeled processor ( IBM 801-IBMs Watson Research Center, mid-1970s ) was a tightly pipelined simple machine originally intended to be used as an internal microcode kernel, or engine, in CISC designs, but also became the processor that introduced the RISC idea to a somewhat larger public.

The first highly ( or tightly ) pipelined x86 implementations, the 486 designs from Intel, AMD, Cyrix, and IBM, supported every instruction that their predecessors did, but achieved maximum efficiency only on a fairly simple x86 subset that was only a little more than a typical RISC instruction set ( i. e. without typical RISC load-store limitations ).

The first IBM drive, the 350 RAMAC, was approximately the size of two refrigerators and stored 5 million 6-bit characters ( the equivalent of 3. 75 million 8-bit bytes ) on a stack of 50 discs.

The word Applet was first used in 1990 in PC Magazine.

The BIOS software is built into the PC, and is the first code run by a PC when powered on (' boot firmware ').

When the PC starts up, the first job for the BIOS is the power-on self-test, which initializes and identifies system devices such as the CPU, RAM, video display card, keyboard and mouse, hard disk drive, optical disc drive and other hardware.

The first Compaq PC was sketched out on a table napkin by Ted Papajohn while dining with the founders in a Houston restaurant.

Under Pfeiffer's tenure as chief executive, Compaq entered the retail computer market with the Presario which one of the first manufacturers in the mid-1990s to market a sub -$ 1000 PC.

While rival Dell Computer had 55 % growth in U. S. PC sales in the first quarter of 1999, Compaq could only manage 10 %.

Solidyne 922: The world's first commercial audio bit compression card for PC, 1990

The first personal computer to make use of the 80386 was designed and manufactured by Compaq and marked the first time a fundamental component in the IBM PC compatible de facto-standard was updated by a company other than IBM.

The first company to design and manufacture a PC based on the Intel 80386 was Compaq.

By extending the 16 / 24-bit IBM PC / AT standard into a natively 32-bit computing environment, Compaq became the first third party to implement a major technical hardware advance on the PC platform.

His first model arrived at dusk.

Stock design is excellent, and this model is a good first gun.

The first to arrive was Émile Levassor in his Panhard-Levassor 1205cc model.

The quantum number n first appeared in the Bohr model where it determines the radius of each circular electron orbit.

Gamow solved a model potential for the nucleus and derived, from first principles, a relationship between the half-life of the decay, and the energy of the emission, which had been previously discovered empirically, and was known as the Geiger – Nuttall law.

The language of the poem is typically direct and concise and comprises short sentences-the first line is in fact a model of condensed meaning, comprising an exhortation (" Let's drink!

image: Apollo17UV. jpg | A model of the UV spectrometer used to take the first accurate measurements of the constituents of the Moon's atmosphere.

The first model was launched in 1985 as a high-end home computer and became popular for its graphical, audio and multi-tasking abilities.

The first model was released in 1985 as simply " The Amiga from Commodore ", later to be retroactively dubbed the Amiga 1000.

On Amiga 1000 ( and first Amiga 500 and Amiga 2000 model ), the power LED had no relation to the filter's status, a wire needed to be manually soldered between pins on the sound chip to disable the filter.

In 1802, at the personal request of Napoleon, Canova returned to Paris to model a bust of the first consul.

Martin Cooper ( inventor ) | Dr. Martin Cooper of Motorola, made the first private handheld mobile phone call on a larger prototype model in 1973.

Newton was the first to develop a mathematical model for calculating the speed of sound, but it was not correct until Pierre-Simon Laplace accounted for the molecular behavior of gases and introduced the heat capacity ratio.

After World War II, Bulgaria followed the Soviet model of economic development more closely than any other East Bloc country with becoming one of the first members of Comecon ; the new regime shifted the economy from mainly agrarian type towards industrial economy and much of the labour force from the countryside to the city, providing workers for new large-scale industrial complexes.
