Update 2023/03/30


This update on MVS Turnkey 4 is discontinued and superseded by MVS 3.8J Turnkey 5.

I have created a new set of disks on top of Jürgen Winkelsmann's MVS Turnkey 4. These updates are installed on top of update 08 of his distribution. I have chosen for a different approach. Now you can download a complete TK4 system or only the modified disks.
MVS is a mainframe operating system of the years seventies until the middle of the eighties. MVS TK4- is OS/VS2 release 3.8J. Successors of MVS 3.8J are MVS/XA, MVS/ESA, OS/390 and z/OS.

You will find MVS TK4- on his site

In SYS1.PARMLIB I haved added IEALPA00. This member becomes active if you specify MLPA=00 in IEASYS00. IEALPA00 contains 38 RPF modules and 4 aliasses.

Other modifications

The HERC01.REVPROF, HERC02.REVPROF, HERC03.REVPROF and HERC04.REVPROF datasets are deleted (REVIEW does not need them anymore).
I have allocated HERC01/2/3/4.ISP.PROF for ISPF and REVIEW and I have allocated HERC01/2/3/4.ISP.PLIB to create your own ISPF panels.
The procedure ADDUSER contains now allocations for &SYSUID.EXEC, &SYSUID.ISP.PLIB and &SYSUID.ISP.PROF libraries.

The initial CLIST is changed and will not call TSOAPPLS anymore, but will go directly to ISPF.

You can download the complete system or the updates by clicking on one of the buttons below:


This modification contains of the updated disks:

  • SMP001

The other disks are identical with the disks of the original version (update 08) of Jürgen's site

  • The complete TK4+ system is indeed a complete system with Hercules, all the conf files, manuals and of course the MVS TK4- system with my modifications.
  • The modifications are only the new- and update volumes.
  • If you use this system for the first time, downloading the complete system is recommended.
  • If using the modifications only, please download and run the catalog job.
