In the talk he did say that for that acient machine he was offered
subscription to the upgraded z/OS for some small amount of dollars a

There is openmainframe project https://www.openmainframeproject.org/ ,
which I believe offers access to z/VM instances hosted by Marist

At the openmainframeproject EU meetup, it was indicated that SUSE
joined with indication that Open Build Service might be able to use
resources hosted by Marist.

I wonder if it makes sense to reach out, and see if there are
resources available to use as porter boxes & build boxes. That way
Debian might be able to get such donated resource available on ongoing
basis and hopefully with some hw support.
