All, The current Hitachi OS is called VOS3, but I'm not sure about the suffix (VOS3/???). I'm also not sure if Hitachi VMS was ported the Hitachi specific z14.
While based on MVS, I think it is fair to say that z/OS and VOS3 have diverged enough from the parent OS to be listed as a separate OS for current z mainframes.

KVM is Linux based hypervisor. Is it OS? Maybe, like z/VM. Is it Linux? Maybe, but specialized. VOS is just (almost legal) clone of MVS, like Fujitsu MSP. Due to legal settlements both are not available outside of Japan, AFAIK. There are also BS2000 (Siemens mainframe) OSes, similar to MVS and VSE AFAIK, but it's hard to find out real roots. I heard both are cloned with (paid) agreement from IBM. And of course z/OS family can be counted as one or as: z/OS OS/390 MVS MFT, MVT, OS/VS1, OS/VS2, OS/360... -- Radoslaw Skorupka Lodz, Poland ====================================================================== Jeśli nie jesteś adresatem tej wiadomości: - powiadom nas o tym w mailu zwrotnym (dziękujemy!), - usuń trwale tę wiadomość (i wszystkie kopie, które wydrukowałeś lub zapisałeś na dysku).
