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 [...]
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 [...]
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 [...]
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, [...]
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 [...]
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 [...]
