The IBM 3090 family is a family of mainframe computers that was a high-end successor to the IBM System/370 series, and thus indirectly the successor to the IBM System/360 launched 25 years earlier.[1][2]
Announced on 12 February 1985, the press releases did not explicitly mention that the two models, Model 200 and Model 400, were backwardly compatible with the 370; instead, they were simply positioned as replacements for the IBM 3033. The IBM 3090/200 version was rated at 18 MIPS and 31,000 UNIX Dhrystones.[3] This was true of the entire line, which expanded with the release of the Model 120E,[4] 150, 150E, 180, 180E, 200, 200E, 300, 300E, 400, 400E, 600E, 600J, and 600S[5] 3090 were described as using "ideas from the ... IBM 3033, extending them ... It also took ... from the ... IBM 308X."[6]
The 400 and 600 were respectively two 200s or 300s coupled together as one system and could run in either single-system image mode or partitioned into two systems.[5]
