The stereotypical techno-geeks are assumed to be nerds who lack basic social skills, are physically unfit, unable to put up a fight and are obsessed more with technology and intellect. Mainframe is well known for his techno-speak and thorough knowledge of computer technology. To assume that he fits the stereotype is wrong. He was a soldier long before he became invested in information technology. He has what it takes to fight and rough it out with the rest of the boys.

Mainframe served in the US Army and actually had two tours of duty before getting his degree at MIT and having a successful stint in the private sector. He was utterly bored with his life when the US Marine Corps had a posting for new recruits with technology skills. He quickly signed up.

  • Working names included CHIP, Big-Byte and Relay.
  • 1986 Mainframe wears a Combat Infantry badge (on the wrong side of his shirt), but does not come with any weapons.[7]
  • The writers' guide for the Sunbow series suggested that Main-Frame [sic] and Zarana would "deliberately avoid harming one another" and "even provide the other an opportunity to escape" whenever they encountered each other after their romantic interlude. However, "such compassion and generosity on their part does bit [sic] extend to other Joes, Dreadnoks, or Cobra troopers.".[8]
  • The Season 5 episode of the CBS television program NCIS that aired October 16, 2007 - "Identity Crisis" - assigned many of the guest stars and incidental characters the names of G.I. Joe characters. Although no character was ever seen, the name "Blaine Parker" was mentioned as a famous and well-respected tattoo artist working in Boston.
