Re: Domain bsp-gmbh.com expired
My timing was excellent, I snarfed the site 2020-06-26. I was way overdue since my prior snarf was 2012-04-21. A different of 567 bytes between the two dates, so even older backups should be nearly complete. All told about 408 MB.
I dropped him a line a few days/weeks ago, but haven't heard back yet, but that's fairly typical. Any response at all tended to come after a lengthy delay.

I built gcc from source once on a Pi Zero.? It took 5 days elapsed wall clock time. But it all worked. Bill

Michael,
Yeah ... no worries ... :-)
Thanks again for the clarifications, not just for myself, but for "the archives" ...

The caveat is that the destination Hercules has to support any forms of compression that the DASD you are moving use. If you are using prebuilt Hercules' *probably* ok, but I got bit once moving some DASD compressed with BZ to a machine where Hercules had not been built with libbz2.

I've switched my MVS and VM images between x64 abd ARM (RPi)

Dave, Should be no reason you cannot. I move DASD images between instances of MVS on different Linux desktops and even non-system DASD from MVT to MVS. Jay

I tried it on a Pi Zero; I ended up giving up. **too** slow, couldn't tell if it was stuck or just slow.
The slow part was getting the SMP volumes built. I think if you followed Jay's instructions to the point where you had your starter system and SMP volumes built, you could move over to a Pi and be ok (and once you have those, you never need to build them again)...
You may have a fighting chance on a Pi 3 or 4.
One thing that was killing me was that I had compressed DASD, which was ****really**** slow on a Pi Zero when doing a lot of writes.

Re: TK4- On a Raspberry Pi
Has anyone done a full sysgen on one of these?? I am referring to following Jay Mosley’s instructions.
Assuming that you follow the Hercules install and compile instructions.?? I’d assume it takes longer than on a much faster Desktop Linux machine – but is it possible and has it been done successfully?
?
Thanks,
Dave

Thank you, sir.? (I must have missed that earlier post.)

Re: TK4- On a Raspberry Pi
Hi Scott, given the lack of reliability of SD cards when dealing with lots of IO activity/filesystem writes, I’d recommend the use of an USB 3.0 attached disk to you. Even though a PI4 cannot completely boot from USB without the help of a boot image on SD, I think it is worth it. I use 512GB SSD ?disks“ on both of my PI4. A beta of a new firmware that may have your PI4 boot directly from an USB 3.0 device is available, but I did not want to toast my PI so I’m waiting until it is safe to upgrade. In the meantime, a redirect of the root partition in the /boot/config.txt helps.
Kind regards

Hi Ed,
Can you share with us the link you found with clear instructions?? I am reluctant to buy a Pi until I know there are reliable instructions to follow!
Also, what is the "best" website to order a Pi 4 or latest model?
Thanks,
ScottC?

Of course, the absolute paths in this simple example must be adjusted to the individual environment. Given the circumstances,? I’ve just did a simple copy and paste.?

And what exactly would "the proper compile options" be, for an RPi4???
