GI JOE MAINFRAME Vintage Action Figure COMPLETE 3 3/4 C9+ v1 1986
Mainframe (version 1) was released by Hasbro and was first released as part of the fifth series (1986). He was also available in 1987 and was discontinued in 1988.
Mainframe came with a black telephone, a gray backpack, a gray handheld computer, and a black hose.
Mainframe enlisted in the Army Airborne at the age of seventeen and made it over to South-East Asia for the last year of hostilities, just in time to get his Combat Infantryman's Badge. He left the Army to get his degree from MIT on the GI Bill and did a stint toiling in the antiseptic corridors of Silicon Valley making big bucks and fighting off boredom with a stick. Luckily the Marines were looking for a few good men with just his qualifications. The proper papers were sign, and Mainframe was back in uniform.
