I answered a question on the #tuhs mailing list with a little history on userspace page 0 in #SunOS and #Solaris :

Cleaning and restoring this SUN SPARCstation 330 from 1989. They built these things like vaults. It’s perfectly clean on the inside but hasn’t been powered on in 30 years.

Yes, the picture accompanying this post was just what I had handy, and was SunOS and not Solaris. To make up for it, here's the CDE Phone.

Someone's old Sun SPARCstation IPX fan page I ran across today, randomly.

I love old pages like this.

Ok, here's the blog post!

If you've wanted to party like it's 1994 and experience life on planet #Unix _before_ Solaris, why not try a bit of #RetroComputing and try #SunOS 4 on an emulated #SPARCstation 5? https://apintandaparma.club/cos/falling-down-a-rabbit-hole-of-nostalgia-episode-1-sunos-4

Falling down a rabbit hole of nostalgia, episode 1 - SunOS 4

(or: running SunOS 4 on an emulated SPARCstation in 2025 with QEMU 10.1.) [...]

Alright, so I fell down the #SunOS 4 #emulation rabbit hole, piecing together a bunch of instructions and finding something that worked. See up and down from this post for more info.

I wonder if it's similarly possible to emulate an old DECstation running Ultrix?

New Friend in #SantaCruz ...

I juggle (learned because SUN Servers came with three sand-balls and in the #SunOS manual, there was a chapter on how to juggle while you were waiting for the OS to install) and so Brah invited me to Tuesday Juggling at Capitola Beach!

I think I'd very much like that.

@yakmoose @kimapr @catsalad: Back in the 90s we did that with kernels. You can actually hear the difference between a #Linux and a #SunOS kernel. 🤓🧔🧓

Today somethin different than FreeBSD for a change (but still Unix!). Brings back so many memories from 2001-2005 when I was administering Solaris machines during my first job.

Even some commands still were in my head like zones (OS virtualization. somewhat like Jails but different isolation :)

# Install zone
zoneadm -z myzone install
# Boot zone
zoneadm -z myzone boot
# Check if zone is running
sudo zoneadm list -cv
# Llogin to zone
sudo zlogin myzone

So much nostangia :-) ☕

What I love about this bit of history is that it means the first non-linear video editing system was done on a #Sun-1 computer running #SunOS.

I'm doing a nostalgic trip to the before days. Installing and running SunOS 4 on qemu-sparc.
I really miss SunView/OpenLook, it was way before it's time.
