The primary operating systems in use on current IBM mainframes include z/OS (which followed MVS/ESA and OS/390 in the OS/360 lineage), z/VM (which followed VM/ESA and VM/XA SP in the CP-40 lineage), z/VSE (which is in the DOS/360 lineage), z/TPF (a successor of Transaction Processing Facility in the Airlines Control Program lineage), and Linux ...
In contrast to Trilogy's goal of introducing their own plug-compatible mainframes and competing with IBM directly, [11] DEC would use similar technology to produce a VAX outperforming IBM's offerings at a lower price point. Trilogy's wiring technologies were used to create card-sized "multi-chip units" (MCUs) working together like earlier multi ...

However, IBM's successor to the z9, the z10, led a New York Times reporter to state four years earlier that "mainframe technology—hardware, software and services—remains a large and lucrative business for I.B.M., and mainframes are still the back-office engines behind the world's financial markets and much of global commerce".
