Sounds good! There's a datacenter in Utah I work with every once in a
while where we sent a used DS8870 with 3-phase power, maybe 4 months
ago. From what I heard it can't be used because it's too difficult or
expensive for them to install 3-phase. I emailed our group about it
when I saw your reddit, but it might be a while before (and if) I get a
reply. But now that I think about it, you would have the same 3-phase
issue.
And unfortunately, individual disks are sometimes pulled out at
decommission time and sent to the crusher for security. That happened
to a perfectly good DS8880 I saw here in California last year.
A question for the z/VM folks here: Doesn't z/VM run with fixed-block
disks, and can it simulate CKD on those disks to run z/OS? Or am I
crazy to remember that from my limited VM exposure in the 80's?

I saw that Timothy Siples already posted this, but I wanted to share some more
information about my new system, and my setup. I am currently a high school
junior located in New York. For the last month or so, I have been in the
process of acquiring a used z114 mainframe (you may have seen my other post
about dasd for the machine). Yesterday, the machine finally arrived. If you
want to see some pictures of the machine please do check out my reddit post
here: https://www.reddit.com/r/homelab/comments/uxsbef/my_new_z114/? At the
time of writing, I have not powered up the machine yet, as I still have to run
and connect the power to my 220v supply. The HMC for my machine is also still
in the mail, and I am expecting it sometime this weekend, or early next week.
My main plan for the machine is to use it to learn everything there is to know
about the platform, and learn the skills that I would need for a career in
mainframe early. I am also trying to get into MIT, and having a unique
accomplishment like this on your transcript can be a big help in that regard.
Currently, I have a FC SAN for FBA storage, but I am still looking for CKD
capable storage. My parents have allowed me to take up to three racks, so if
you know of anyone trying to get rid of some, no matter how old it is, I will
pay shipping to me. I expect to be posting alot more here as I deal with the
myriad chalanges involved with getting the machine set up. If you have any
questions you would like to ask, please feel free to do so. I will do my best
to reply thoughout the day.
Thank you,
Enzo Damato
