ABSTRACT
<p>The MF7114 was an early 4-bit single-chip microprocessor designed and built by Microsystems International between 1970 and 1972. The MF7114's genesis is the design work on Intel's first microprocessor, the 4004. Exploring the MF7114 microprocessor's development helps to gain a more complete historical perspective on the formation of the microprocessor and microcomputing industries.</p>

1. The research reported in this article is based primarily on documents released by Microsystems International between 1972 and 1974. It also significantly relies on oral histories because there is a lack of relevant primary and secondary sources on these topics, such as the genesis of the Intel 4005 chip. Quotations by J. Freeman, J. Heckman, M.E. Hoff, J. Monico, and S. Mazor, were obtained through interviews and email correspondence with the author between 2003 and 2008.
