Editing intel/mcs-4/4004

The '''Intel 4004''' was the first commercially available [[microprocessor]] in history released by [[Intel Corporation]] in 1971. The 4004 was a [[4-bit CPU]] designed for use in the Busicom 141-PF printing calculator<ref>[http://www.intel.com/content/www/us/en/history/museum-story-of-intel-4004.html The Story of the Intel® 4004]</ref>. The chip, which clocked at 740 KHz, employed a 10µm<ref>[http://www.intel.com/Assets/PDF/DataSheet/4004_datasheet.pdf 4004 Datasheet]</ref> process silicon-gate, capable of executing 92,000 instructions per second. The chip was capable of accessing 4KB of [[program memory]] and 640 bytes of RAM. The 4004 was part of the [[Intel MCS4]] system.

The microprocessor had a limited architecture such as only 3-levels deep [[stack]], a complex memory access scheme, and no [[interrupt]] support.
