Roland BS3000 was the original FACOM/OSIV operating system from Fujitsu - actually a copy of MVS Sp 1.3 - mostly the comments in the source has been changed . I was working in support for this in 1983 - heavy looking in microfiche. BS3000 also run on FUJITSU HW - as MVS also at this time - but most customer preferred MVS. Machine Types was 7890 , 7860 - in the 3083,3081 and 3084 times .
BS2000 was originally developed by RCA iirc - in the times of 360 . BS2000 was running on SIEMENS HW and later on compatible HW from FUJITSU - but there is no TSO . BS2000 has the same command language for Batch and ONLINE - no difference between TSO and JCL . And IIRC the data is organized in PAM-Pages - each 4K . No DSORG,BLKSIZE etc. So it is mostly different - only low level it is MVS-like . And i think today the same machines still run BS2000 for Siemens as FACOM in Japan . Frank It's close. The Assembler instructions are the same based on the 370 architecture. The macros differ. Cobol is also very close but without IBM extensions. The EBCDIC codepage differ for german umlaut. About 15 years ago you can IPL MVS on a siemens hardware but require intervention from Siemens. I never worked on BS2000 just on a CICS-UTM connection. BS2000/OSD the OS is complete different. BS3000 was close to MVS but IBM persue Siemens and BS3000 was dead.
