The 5965 is a miniature twin triode vacuum tube (thermionic valve) "designed for use in high-speed digital computers".[1]
According to an MIT Project Whirwind memorandum, the tube was developed c.1953 for IBM by GE, primarily for use in the IBM 701 computer, and was designated as a general-purpose triode tube.[2] In European use the tube was labelled E180CC; sometimes the same tube was labelled with both names.[3]
