At the time the S/360 was announced, CDC, GE and UNIVAC had block relocation in the hardware. Ferranti had paging. Burroughs had segmented virtual memory. IBM had paging in the laboratory. And S/360? S/360 had nada. > From the very outset the OS/360 design included a relocating > loader, which was very advanced for its time. You're confusing S/360 with OS/360. Fetch was software. Further, once a program was loaded it could not be moved, despite the vain hopes of those developing VMS (no, not that VMS.) > Neither, BTW, did Burroughs, NCR, or Bendix. > Univac held on much longer. Burroughs continued selling the B2500 and B6500 lines for a considerable amount of time. More to the point, the degree of market success tells nothing about what technological features were present. > As I went about learning PC's (and Apple) operating systems (including > Win32) I was struck with the fact that much of what was the "new" thing was > just a reimplementation of what we did on the S/360 in the mid '60's. There we agree. The PC industry has been characterized by reinventing the wheel and by the NIH syndrome. -- Shmuel (Seymour J.) Metz
