Intel 8008

text from wikipedia. the second generation of Intel Microprocessor. beautiful. Intel 8008 The Intel 8008 was an early byte-oriented microprocessor designed and manufactured by Intel and introduced in April 1972. It was an 8-bit CPU with an external 14-bit address bus that could address 16KB of memory. Originally known as the 1201, the chip was [...]

Intel 4004

Intel 4004. the first microprocessor in the world. text from wikipedia. The Intel 4004 is generally regarded as the first microprocessor, and cost thousands of dollars. The first known advertisement for the 4004 is dated November 1971 and appeared in Electronic News. The project that produced the 4004 originated in 1969, when Busicom, a Japanese [...]

Semiconductors and microprocessors

Semiconductors and microprocessors (from Wikipedia) Computers using vacuum tubes as their electronic elements were in use throughout the 1950s, but by the 1960s had been largely replaced by transistor-based machines, which were smaller, faster, cheaper to produce, required less power, and were more reliable. The first transistorised computer was demonstrated at the University of Manchester [...]

Motorola 6800

I didn’t know Motorola was making microprocessor before. I thought it was just cellphone company. Interesting. text from wikipedia. Motorola 6800 The 6800 was an 8-bit microprocessor designed and manufactured by Motorola in 1974. The MC6800 microprocessor was part of the M6800 Microcomputer System that also included serial and parallel interface ICs, RAM, ROM and [...]

RCA 1802

text from wikipedia. The RCA CDP1802, also known as the COSMAC (Complementary Symmetry Monolithic Array Computer), is an 8-bit CMOS microprocessor (µP) introduced by RCA in early 1976. It is currently being manufactured by Intersil Corporation as a high-reliability microprocessor. The 1802 has an architecture different from most other 8-bit microprocessors. In 1970 and 1971, [...]

Signetics 2650

text from wikipedia. my memo regarding the history of microprocessor. The Signetics 2650, was a very early (1975) 8-bit microprocessor. According to Adam Osborne’s classic book An Introduction to Microprocessors Vol 2: Some Real Products, it was “the most minicomputer-like” of the microprocessors available at the time. Signetics sold development boards e.g. the PC1500 “Adaptable [...]

General Instrument CP1600

text from wikipedia. General Instrument CP1600 The CP1600 was a 16-bit microprocessor created in a partnership between General Instrument and Honeywell in the 1970s. The CP1600′s design was based on the PDP-11, whose design also formed the basis of the Western Digital MCP-1600 and influenced others. Honeywell used the CP1600 in a number of process [...]


The POWER2, originally named RIOS2, is a microprocessor designed by IBM that implemented the POWER instruction set architecture. The POWER2 was the successor of the POWER1, debuting in September 1993 within IBM’s RS/6000 systems. When introduced, the POWER2 was the fastest microprocessor, surpassing the Alpha 21064. When the Alpha 21064A was introduced in 1993, the [...]
