=== MK5065 ===
In 1974 Mostek introduced the [[Mostek 5065|MK5065]], an 8-bit PMOS [[microprocessor]], with 51 instructions whose execution times range from 3 to 16 μs. Architectural features included multiple nested indirect addressing and three register sets (each consisting of an accumulator, a program counter and a carry/link bit) which could be used for interrupt processing or for subroutines.<ref>{{cite journal |title=Mostek 5065's by the 1000's |journal=Microcomputer Digest |date=February 1975 |volume=8 |issue=8 |pages=1–2 |url=http://www.bitsavers.org/magazines/Microcomputer_Digest/Microcomputer_Digest_v01n08_Feb75.pdf |access-date=10 January 2021 |publisher=Microcomputer Associates Inc}}</ref><ref>{{cite book |title=Integrated Circuit Guide |publisher=Mostek |date=1974 |pages=78–80 |url=https://archive.org/details/bitsavers_mostekdatagratedCircuitGuide_14005467/page/n79 |access-date=2021-11-04}}</ref><ref>Mostek 5065 instruction set: {{cite book |title=A Microcomputer Based Substation Control System |author=Billy Don Russel, Jr. |date=1975 |pages=108–112 |publisher=University of Oklahoma |url=https://shareok.org/bitstream/handle/11244/4115/7615823.PDF |access-date=2021-11-04}}</ref> [[Bill Mensch]] was one of the engineers who had actually designed the 5065 at Motorola for Olivetti.{{cn|date=March 2024}}
