When using a pre-built system image such as the "VM/370 sixpack" or "MVS Tur(n)key" under Hercules, when a user connects a 3270 terminal, a login screen comes up with a banned identifying the install (sixpack with one closer to the original VM/370 one, and Turnkey with a full custom one). How does one customize those screens? Is there a simple way to restore them to the original IBM provided one?

    First you have to find an IBM custom system integrator. Then you have to get out your checkbook and write a number with a lot of zeros after it ...

    From what I remember from 40+ years ago this was just an assembler source file that you edited and put in the build.

It is now 33 years since I last touched anything remotely connected (no pun intended) to VM/370, VM/SP, or MVS, and the little grey cells are now full of C#, Entity Framework, and SQL Server rather than BAL, CICS, and DL/I. However I did find this page which describes in detail the process for modifying the MVS VTAM 'map' for the signon screen:

    @JacobKrall I did - I said the linked page 'describes in detail the process for modifying the MVS VTAM 'map' for the signon screen'. The key words here are 'in detail' since this is not a trivial process susceptible to summarisation, and to reproduce sufficient of the process here to make this a self-contained answer would require near-complete plagiarism of the original document.

  • I changed the link to an archive.org immutable URL as a starting step. The instructions are also specific to the TurnKey 4 MVS distribution, but are close enough for me to start figuring it generic instructions.
