The '''MCS-80''' ('''Micro Computer Set-80''') was a family of {{arch|8}} microprocessor chipsets developed by [[Intel]]. Introduced on April, 1974, the MCS-80 featured the {{\|8080}} CPU, the forefather of all modern [[x86]]-based microprocessors.

== History ==
{{empty section}}

== Members ==
The original {{\|8080}} had an issue that prevented it from working with external TTL components as intended. This was fixed with the introduction of the "A" versions.
