Abstract
The first two microprocessors — the 4004 (a four-bit set of devices) and the 8008 (an eight-bit device on a single chip) — were produced in the early 1970s by a newly formed company, Intel Corporation. The 4004, also known as the MCS-4, was designed to replace six custom chips in a desktop calculator and was therefore programmed for serial, binary-coded, decimal arithmetic (a very common practice in handheld and desktop calculators). Although the client, a Japanese manufacturer named Busicomp, went out of business before it could put the 4004 to work, this set of devices was soon adapted for numerous other applications.
