The IBM System/360 Model 22 was an IBM mainframe from the System/360 line.

History

The 360/22 was announced less than a year after the June 22, 1970 withdrawal of the 360/30, and it lasted six and a half years, from April 7, 1971, to October 7, 1977.

Editorial summary

Begin with the source’s own compact description: “IBM System/360 Model 22” is low-end IBM computer model from 1970. The dossier treats that line as a proposition to test through System, Model and Low-end, not as a finished interpretation.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current lead gives the account dated anchors—1970, 1971, 1977—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, System, Model and Low-end is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “low-end IBM computer model from 1970” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated May 7, 2026. The linked authority identifier is Q5969046. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1970, 1971 and 1977.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
