RE: Sun Ultra 25
Did you have any luck? I have a similar issue with the ultra 45.

The oracle link is paywalled: https://updates.oracle.com/download/9625162.html

I have a lead for a download for the ultra 45 (http://bbs.chinaunix.net/thread-3744881-1-1.html) on a chinnese forum, but I can't create an account because they use sms verification and my country is not an option for that. :(


If you know the patch number, you can usually look for the patchnumber.zip and there is a chance it will pop up on google. Looks like the one for the ultra 25 would be patch 142704-01 according to https://archives.retrobridge.org/sun/sys...i.html#U25

They seem to have the ultra 25 patch, but not my ultra 45 :(

This would be the ultra 25 link: https://mirrors.pdp-11.ru/_sun/sun_sparc...704-01.zip and on archive.org: https://archive.org/details/142704-01

My apologies, the file names are too similar. Glad you found it.

No worries.

All is well and while the ultra 25 files might not be useful to me, they should be good for someone else and I also managed to source the ultra 45 files in the end.
