Intel Inside
The first commercial microprocessor, the Intel 4004, was originally ordered by the Busicom Japanese company for exclusive use in their line of desktop calculators. It was delivered in early 1971.
Intel was then able to re-negotiate the rights to build 4004 processors for other customers. The Intel 4004 was introduced as the first commercially-available microprocessor in November 1971.
Busicom went bankrupt in 1974. Intel makes $10 billion a year selling (mostly) microprocessors as of 2014.
(Thanks Wikipedia!)
This processor is a 4004 rev. C socketed into the main board of a Busicom 162-DE calculator, released in 1972. Note the 3-digit batch number: B0461. The markings on top of the die (保税) is a stamp of the Japanese customs.
The calculator stands on my desk, in perfect working condition.
Taken with an Auto-Topcor 5.8cm f/1.8 lens with Exakta-mount macro extension rings.
