Guy Harris (talk | contribs) Some said" means "the author of the Computerworld column said", so use it as a reference. Remove a non-reference footnote whose relevance is not clear (other than that, as noted in the "Virtual memory" section, those two models, unlike all subsequent models, needed an expensive hardware upgrade to support VM). The "not real 370s" applied to the 155 and 165, not the 145, which already had the hardware necessary for VM, and only needed a microcode update. |
Guy Harris (talk | contribs) →Growth path: *This* edit removes the "extended, not redesigned" quote. Set up a "Virtual memory" section like the one in IBM System/370 Model 165. |

Line 61:
The 370/155 was described as able to "run under [[DOS/360 and successors|DOS]]." Both the 155 and the larger 370/165 could "run under [[OS/360 and successors|OS/360]]." Being members of the System/370 family, the Model 155 and Model 165 were compatible with each other. Neither machine, as announced, could run a virtual memory operating system.

The initially announced
In 1972 an upgrade option was announced "to provide the hardware necessary to operate in a virtual memory mode."<ref>{{cite news|newspaper=Computerworld|date=August 15, 1973|page=17|title=First IBM DAT Box Installed|url=https://books.google.com/books?id=T3qky0Z-gc0C&pg=PA17}}</ref>
