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 :-

How is BRexx different from Rexx?
Hello, As suggested, I'll be writing the BM Backup program using Rexx / Brexx. I would appreciate knowing the differences because the goal is for the project to run on both VM/CE & real iron. Thank

Re: Adding disks found in DMKRIO and CPEREP error
Hello Mark, I suspect part of it is your changing the font. I'll give it a try. BTW, how does one specify the various model numbers? Is it the Model5.wc3270? Does VM/CE support the 3279? Does WC3270

Re: Adding disks found in DMKRIO and CPEREP error
Bertram, Sorry for the delay. Too many irons in the fire, and too many grandchildren (just one) to watch. ;-) I set up VM/370 CE V1R1.2, under Hercules 4.4.1 on Windows 10. IPLed it and opened a model

Re: AP and/or MP support in VM/CE: Does it exist or no?
Yup, at OCF we had 3033 and 3031 systems. The 3033 was MP and the 3031 was AP.

Hi Dave, Yes, I am beginning to learn. I just was hoping something could be done for those in the future who want to run Hercules.

Re: AP and/or MP support in VM/CE: Does it exist or no?
Dave, I agree. MP might be of benefit, but there are many, many other items ahead of it.

Re: AP and/or MP support in VM/CE: Does it exist or no?
Hi, At OCF, we used our AP strictly for compute bound programs. I was at the research facility and users we doing fluid dynamics of fire, wind, cold air, hot air, etc, we had need for an AP. I take it

Re: AP and/or MP support in VM/CE: Does it exist or no?
My recollection (fuzzy as it may be) is that MPs were available before APs. (The hardware, I mean, not the OS support.) Of course the 360/65 had an MP option, but it was architecturally a bit

Re: AP and/or MP support in VM/CE: Does it exist or no?
Jay, MP support was not available until VM/SP. Mark's port details the reasons that AP support is so poor in VM/370; he is correct. Regards, Bob

Re: AP and/or MP support in VM/CE: Does it exist or no?
I also worked in a shop that had a 158, and upgraded it to an AP, with a total of 6 MB of main storage (4 MB was Memorex add-on memory).? It also worked well for MVS.? IIRC, it also worked

Re: AP and/or MP support in VM/CE: Does it exist or no?
OK, so I'm curious. MPs were available at the same time asAPs, IIRC. Was MP support strictly a VM/HPO feature? Base MVS 3.8 works on AP/MP systems just fine. My first sysprog job was on a 370/158AP

Re: AP and/or MP support in VM/CE: Does it exist or no?
AP support is available in VM/370? (not MP), but I wouldn't recommend bothering with it.? Because of the limitations where the attached processor cannot do i/o, it forces a lot of extra overhead

If you do a generic (default) Google search for "hercules390 emulator", the first link returned is for the VERY old/obsolete original "http://www.hercules-390.org/" web site for Hercules version 3.07
