This group is for all folks running the original IBM VM/370 Release 6 operating system (or later (e.g. VMTCE (Community Edition)) on Hercules. Like the other early IBM operating systems this version has always been in the public domain and so can be freely distributed. The base version as supplied by IBM is lacking in many facilities. IBM solved this by providing additional extension products which were licensed and so are not available. There are however many user enhancements available which can be installed. In addition, in order to get users up and running quickly updated "releases" of VM/370 included the most popular updates are available for download, so novices can start to learn VM without having to delve into the system internals. It is intended that this wiki will provide information on the base release and these updates.
The available versions are here :-

Hi, My first job out of college was with Texas Instruments. I chose TI for two reasons: 1) It was my understanding the BSEPP and SEPP work were done at TI main site. 2) The job was to be the first and

Re: Issue with HRC075dk (Alternate nucleus)
It is important to remember, we are playing with an operating system from the late 1970s through early 1980s, about 40 years ago, which IBM got no money for developing. It only aided in hardware

Re: Issue with HRC075dk (Alternate nucleus)
William, It seems to me that you are misunderstanding how to use the alternate nucleus arrangement. First off, DMKSYS is a table of parameters; the resulting assembly doesn't contain any code. If you

Re: XNET v1.4.1
Hi Mark, Ok, I think I see the problem.? You are reusing the same port numbers on your CTCE definitions in your Hercules configuration.? They need to be unique, by CTCE device. For example, you have

Issue with HRC075dk (Alternate nucleus)
Why should we need to change DMKSYS depending on where we want the nucleus loaded and IPL'd?? The whole idea of "alternate nucleus" is to be able to test a new prod nucleus and be able to fall back if

Updating Directory in VM370CE r1.2
Maybe I am having a senior moment but I don't see a good way of running the DIRECT command from MAINT on VM370CE.. The active directory does not seem to have any full-pack minidisks to map the system

Re: Networking a selection of Hercules systems running VM/370rel6
This is only true if Hercules SDL is dynamically creating the interface on Linux or perhaps some other platforms.? If the interface is created outside of Hercules these privileges are not required.
