Editing IBM 650 (section)

==History==
The first 650 was installed on December 8, 1954 in the [[Comptroller|controller]]'s department of the [[John Hancock Financial|John Hancock Mutual Life Insurance Company]] in Boston.<ref>{{cite web|url=https://www.ibm.com/ibm/history/exhibits/650/650_ch1.html|title=IBM Archives: 650 Chronology|archive-url=https://web.archive.org/web/20230417002435/https://www.ibm.com/ibm/history/exhibits/650/650_ch1.html|archive-date=2023-04-17|url-status=dead}}</ref>

The [[IBM 7070]] (signed 10-digit decimal words), announced 1958, was expected to be a "common successor to at least the 650 and the [[IBM 705|[IBM] 705]]".<ref>{{cite book |title=IBM's Early Computers |last1=Bashe |first1=Charles J. |last2=Johnson |first2=Lyle R |last3=Palmer |first3=John H. |last4=Pugh |first4=Emerson W. |year=1986 |publisher=MIT |isbn=0-262-02225-7 |page=[https://archive.org/details/ibmsearlycompute00bash/page/473 473] |url-access=registration |url=https://archive.org/details/ibmsearlycompute00bash/page/473 }}</ref> The [[IBM 1620]] (variable-length decimal), introduced in 1959, addressed the lower end of the market. The [[UNIVAC Solid State]] (a two-address computer, signed 10-digit decimal words) was announced by Sperry Rand in December 1958 as a response to the 650.  None of these had an instruction set that was compatible with the 650.
