OpenEdition was introduced in MVS 4.3 in 1994 but was an almost unusable subset, it only had POSIX support, Kern shell and dbx debugger. MVS 5.1 less than a year later added TCP/IP 3.1 and NFS, making it borderline usable. In 1996 along came OS/390 V1R2 which rebranded it as USS along with adding some real capability. Those were the days when new release of OS/390 every 6 months, to keep up with Sun Unixes. It's fair to say that the first useful Openedition was 5.2.2 in 1995, and the first "production ready" USS was OS/390 V2R9 in 2000 (that had shared HFS, sysplex and some RACF integration). Come a long way since then.
