Intel 8088

Intel 8088 microprocessor technical specifications

Developed by: Intel
Launched: 1979
ALU bits: 16
Clock: 4.77 MHz until 16 MHz
Family: x86
Registers: 16 bits
Bus: 8 bits
Mem. Address: 20 bits
Transistors: 29 000
Technology: 3 µm
Pin num.: 40 pins
Socket: DIP

A reduced-cost version of the Intel 8086 with a data bus reduced to 8 bits so that it could use circuitry from previous-generation computer manufacturers and thus reduce computer costs.

NEC's i8088 Clone

Through reverse engineering, NEC created a chip that was pin-to-pin compatible with the Intel 8088 microprocessor.
The chip has approximately 29,000 transistors, and the clock speed is between 8 MHz and 10 MHz (16 in later models).
The NEC V20's design was more efficient than the 8088, allowing it to run 30% faster at the same clock speed, depending on the application. The main feature that made it run faster was that it had hardware multiplication, while Intel's chips performed multiplication using microcode software.

Manufacturer: Motorola
Launched: 1979
Bits: 16
Clock: 2 MHz
Transistors: 68 000
Technology: 3 nanometers

It takes its name from the number of transistors it contains.
It was the first in a family of microprocessors that included the Motorola 68008, Motorola 68010, Motorola 68020, Motorola 68030, Motorola 68040, and Motorola 68060 microchips. It was also known as the 68k.
It powered the popular Commodore Amiga and Atari ST computers, and the first Macintosh computers.
It also powered the Sharp X68000 (sold only in Japan) and the first Capcom arcade video game motherboards.

Manufacturer: Zilog
Launched: 1979
Bits: 16

A 16-bit microprocessor with a completely orthogonal register set, featuring a user mode and a supervisory mode.

Its architecture was designed by Bernard Peuto, while the logic and physical execution were carried out by Masatoshi Shima.

The Z8000 was not compatible with the Z80, so it didn't benefit from a large software package.
However, there was a version of the Xenix operating system for the Z8000.
