Guy Harris (talk | contribs) Remove from the "Limitations" section material that also appears in the lead. The remaining section is about OS support; move it after all the hardware stuff, and rename it "Operating systems'. Provide a reference for the DOS and OS support; it doesn't have the exact quotes, so just say it supported both DOS/360 and OS/360 |

Line 52:
Three months later a fourth IBM System/370, the [[IBM System/370 Model 145|Model 145]], was announced.
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.▼
