Successors of IBM tabulating machines and early small mainframes.

  • IBM 1400 (1959)
  • System/3 was the first of the IBM midrange systems (1969)[1]
  • System/32 (introduced in 1975) [2] was a 16-bit single-user system also known as the IBM 5320.
  • System/34 (1977) was intended as successor to both the 3 and the 32.
  • System/38 (1979) was the first Midrange system to have an integrated relational database management system (DBMS). The S/38 had 48-bit addressing, and ran the CPF operating system.
  • System/36 (1983) had two 16-bit processors with an operating system that supported multiprogramming.
  • AS/400 was introduced under that name in 1988, renamed eServer iSeries in 2000, and subsequently became IBM System i in 2006. It ran the OS/400 operating system.
  • IBM System i was subsequently replaced by the IBM Power Systems in April 2008.
