Hi John,
I know nothing about MTS, but I played with it once out of curiosity to get it up and running.? Since I still had the image laying around, I tried running it on Hercules 4.7 running in an Ubuntu 22.04 Hyper-V VM on Windows 10.? MTS appeared to run fine.? It IPLed, I was able to log on as ST01 and do some of the things described at try-mts.com, and I shut it back down.
Hercules was version "Hercules version 4.7.0.10956-SDL-DEV-g1645bfa2", built using hercules-helper on 6/18/2023.? Not bleeding edge, but I don't use that Linux/Hercules all that often.? If necessary, I can upgrade to current and run the test again.
I'll attach the log and config files so you can see what I did.

I can confirm that I have d6.0a running here as well, on an M1 Ultra Mac Studio running macOS 13.5.1. The hercules version is?4.7.0.11007-SDL-DEV-gcddce71b building using Hercules-Helper?v0.9.14-43-g88ec36e-dirty back in July.
In addition to doing the IPL and some basic commands including creating my own account, I also left it running for a day or two to see if it would crash after some period of time. It didn’t — it remained stable the whole time until I manually shut it down.
There are some differences in my config vs. Jeff’s, so I’ve included mine here as another data point.

You’re not going to believe this (or maybe some will). ? I’m used to trying long shots to get things to work, and I came up with an idea and said “… nah – that can’t be it”. ?

Interesting!
What TN3270 software do you all use? The one that I have that works is Mocha TN3270, but it has hideos fonts.
I mostly use ‘x3270’ here on macOS, and have also played a bit with ‘c3270’. At one point I think I looked into using ’tn3270’, but it doesn’t look like that has been updated since 2013 and the binary for that doesn’t run on modern versions of macOS.

Hey John,
On my Ubuntu VM test, I used the local x3270 on the console (DS01) and WC3270 from my Windows system on the interactive user session (DS02).

Jeff - After discovering the 3270 terminal software issue last week, I've come to the conclusion that the issue is caused by using the Vista 3270 terminal software as the operators console (unit 001) during the initial bootstrap of MTS.
As Tom V. said, there are different pieces of driver code running 3270's depending on which phase of the IPL process is happening. It appears that the combination of Vista 3270 -> Hercules 4.x -> MTS d6.0a has issues when used as
the operator's console during the very initial phases on the IPL process.
?
I got it to work by using Mocha 3270 as the operator's console. I can use Vista 3270 just fine for the regular terminals.
I have had d6.0 running just fine under Hercules 4.7 (devel branch) on Centos 7 and NetBSD 9.3 (under an Antsle VM) and Ubuntu 22.04 on an AWS VM.?
I never would have guessed that it would be the choice of terminal software that would be the cause of the problem and tried Mocha as a last resort because I couldn't think of anything else to try.

There is no mode in which using Vista 3270 as the master console works without causing a superdump in the early stages of IPL of MTS when running Hercules 4.x.?
Note, this is not the case for Hercules 3.x (3.06, 3.13). They don't exhibit this behavior.
I will see about opening a ticket in order to help diagnose the problem.

I would like to add some information to this discussion. When you
attach a 3270 telnet device (which is what you are doing when you
configure a 3270 type device), the device is creating a session with a
TN3270 server implemented within Hercules. The built-in TN3270 server
interacts with the 3270 CCW driver within Hercules.
There are two very different versions of Hercules here: 3.x and 4.x.
There was a lot of work done in version 4 related to telnet based
communications. In version 4.x, the TN3270 server is implemented with
the help of an external package whereas in 3.x the server was totally
part of Hercules. The two versions _are_ different.
It is entirely possible that Hercules 4.x is working as designed, but
triggering a very negative response in MTS when Vista is the client.
Why might 3.x work? 3.x may, by happenstance, be shielding MTS from
whatever Vista is sending that MTS does not like. ?
Is it working as designed? a bug? and which component?
This will be a challenge to resolve.

stages of IPL of MTS when running Hercules 4.x. Educate me: what is a "superdump"? And how can I tell it has occurred? Because I finally got around to trying MTS for myself, and it seems to work just fine for me on Windows with Vista 3270. The *only* thing that doesn't work is a 3270 model-5-E (27x132), which causes Vista to complain about an invalid buffer address (see attached). But that's not Vista's problem. That's MTS causing that! And the same thing occurs when I use Hercules 3.13 too! As long as I stick with a model-4-E (43x80) or a model-3-E (32x80) or a model-2-E (24x80) however, then it seems to work just fine on both Herculeses. (Herculi?) Are you *SURE* you're connecting your Vista 3270 session to MTS's 3270 display terminal address 0001 as a 3270 model 2 or 3 or 4? (i.e. NOT as a model 5?) (see attached) Can we see a screen shot of Vista's connect dialog? As well as Hercules's logfile where it reports the connection? (e.g. "HHC02914I 0:0001 COMM: client 0 negotiations complete; ttype = 'IBM-3278-4-E'") Note, this is not the case for Hercules 3.x (3.06, 3.13). They
don't exhibit this behavior.
For me, using a 3270 model-5-E (27x132) *always* causes problems, even for Hercules 3.x (3.13), whereas using any other model (e.g. 2, 3 or 4) works beautifully, just as it does with SDL Hyperion 4.6 too. <shrug> Then it certainly sounds like there is a bug in SDL Hercules
which needs to be investigated! Which I now suspect MIGHT not be the case! It all depends on: 1. What a "superdump" is. 2. Whether you're using a model-5 or a model-4, 3 or 2. 3. Whether you're using NetBSD or not. 4. Whether your Hercules is running natively or in virtual machine (e.g. VMware on Windows, VirtualBox on Linux, or some other virtual machine running elsewhere, such as the AWS you mentioned before). I will see about opening a ticket in order to help diagnose the problem. Thank you. I would appreciate that very much.
Yes! PLEASE! We need to get to the bottom of this! There is something very unusual with whatever system/environment you're trying to run SDL Hyperion + MTS on! -- "Fish" (David B. Trout) Software Development Laboratories mail: fish@...

Fascinating story about bug swatting.
May I suggest the MTS guys (especially Rupert Lane, if he is here) to just add a note to try-mts.com telling people to either avoid Vista or to be careful when using 4.x?
All the best
