Wasn't MYCROFT an acronym for several words ?
NO ! The acronym was "Lunar infrastructure and machinery are largely
managed and controlled by HOLMES IV ("High-Optional, Logical,
Multi-Evaluating Supervisor, Mark IV"), the Lunar Authority's master
computer, on the premise that having a single, large-capacity computer
to run everything is cheaper (though not safer) than multiple
independent systems.[5]"

"The narrator is Manuel Garcia ("Mannie") O'Kelly-Davis, a computer
technician who discovers that HOLMES IV has achieved self-awareness -
and developed a sense of humor. Mannie names it "Mike" after Mycroft
Holmes, brother of fictional Sherlock Holmes, and the two become
friends.[6]"
I really need to read TMIAHM again, it is sitting in my SBR. Along with
the sequel, "The Rolling Stones", the final years of Hazel Stone.
