The Pentium microprocessor had an architecture capable of executing two operations at once.
The Pentium's introduction was intended to eliminate competitors producing clone microprocessors, such as AMD (Advanced Micro Devices), which created the K5, or Cyrix, which produced very good 486s.

An evolution of the Pentium, but with RISC architecture.
It was very inexpensive, but suffered from a problem with floating-point calculations, which was called flag erratum. It was soon discontinued.

Core i5 is a term used to designate mid-range or high-midrange processors from Intel. They are characterized by an affordable price and sufficient performance to be used in computers capable of running complex programs or games that require slightly more power.

The i5 family offers an average processing speed of around 3.5 GHz and a cache of around 8 MB.

This computer, about the size of a suitcase, will be the progenitor of modern portable computers, an honor shared with the Osborne 1 (which used CP/M) and the Hyperion (although it used MS-DOS as its operating system, it was not fully compatible).

It could be purchased with a color (CM) or monochrome (MM) monitor.
And with floppy disk drives for low-density (PC1512SD) or double-density (PC1512DD) disks.
This computer initially didn't have a hard drive, but one could be included. Its floppy disk drives could also be replaced with high-density ones.

The keyboard:

When Amstrad manufactured the PC1512 in 1986, it was careful to avoid any conflict with IBM and made sure not to infringe any of IBM's patents on the IBM PC. In fact, there were very few patents registered other than the keyboard interface.

Therefore, Amstrad designed a new keyboard interface that was quite different (and therefore incompatible) with the IBM interface. The connector and protocols were different, so an Amstrad keyboard cannot be used (even with an adapter) with an IBM PC, or vice versa.

The proprietary keyboard interface was used on all machines in the 1000, 2000, 3000 and 4000 series. Later (from the 5000 series onwards), Amstrad followed what had become common practice and switched to the IBM PS/2 keyboard interface.

This was an update to the previous model, the PC1512, which increased the RAM to 640 KB and incorporated EGA graphics.

There was a version with a dual 5.5-inch floppy disk drive or a hard drive (PC1640HD20).

It was released a few months after the Model 30. Designed as a low-cost model for the home, it eliminated the MicroChannel bus and replaced it with the previous ISA bus so that users could use more common and cheaper cards.

Innovations: Introdujeron el bus MCA, y la conexión
para la interfaz de teclado y mouse, que se llamó también "PS/2".

La interfaz de teclado PS/2 es electrónicamente idéntica a la ampliamente usada PC/AT, pero en lugar del conector DIN de 5 pines se usa un conector mini-DIN de 6 pines.
La interfaz del ratón es físicamente idéntica, pero muy diferente de la RS-232 usada hasta entonces.
Para ambos conectores existían adaptadores.
Y como ambos conectores (de teclado y ratón) eran idénticos, Microsoft, con la norma PC 97, les asignó ser coloreados con diferentes colores.

Hoy en día la conexión de estos periféricos ha sido sustituida casi completamente por USB.

Tambíen fueron los introductores del nuevo estándar de vídeo VGA.
