We seem to be having a lot of "emulators for old Unix boxes exist" posts recently? It's sort of neat, but kinda not news really. Now, I'm off to port Hercules to QNX to make my car an IBM mainframe.

Of those, I found the NeXTSTEP one to be the most interesting. Because the software was the most interesting part of NeXT and you can experience it and see where a lot of current tech came from. InterfaceBuilder at the time was mind-blowing. You can see where XCode autolayout comes from and why many classes are named NS*.

I also prefer the NeXTSTEP filebrowser to be the most convenient to use, especially the long operations that don't open windows to say "hey, I'm still doing this over here." Even the menu shortcut labeling was simple, 'p' means menu-p, and 'P' means menu-shift-P, and '^p'/'^P' for ctrl-p/ctrl-shift-p.

Yeah agreed. There was the adafruit one too. Though I'd love to see a PA-RISC emulator for the old HP-UX with VUE. But that's not around unfortunately.

Seems that 32-bit mode emulation mode of PA-RISC is available, and HP-UX 9 to 11 runs on it: * https://parisc.wiki.kernel.org/index.php/Qemu * https://astr0baby.wordpress.com/2019/04/28/running-hp-ux-11-... There doesn't seem to be enough interest to really make more capabilities a priority beyond hobby-level interest: * https://wiki.qemu.org/Features/HPPA

Nice one!! I looked a few years back and it wasn't there. Will try it.

You can run HP-UX 9.0 on top of MAME, and get VUE in an emulated environment. I have tried this myself and can confirm that it works. https://parisc.wiki.kernel.org/index.php/Running_HP-UX_9.0_o...

Hmm interesting. I haven't used HPUX 9 and am more interested in 10.20 as this was what I used back in the day (on PA-RISC, I think this was no longer supported on Motorola).

But I'll try it nevertheless. Thanks!

Yes, not news but definitely interesting. Some of these old unixes were only available for multi-thousand dollar machines. Current computers are powerful enough to run these systems somewhat comfortably inside emulators or using JIT or dynamic binary translation... If 30 years ago you dreamed on using any of those systems, now you can do it.

On the other hand, the only real reason you’d want to run AIX is because you had to, because you had the hardware and there was no other option.

Or just for the fun of it as a hobbyist.

I worked with AIX on Power5/5+ (mid 2000s) and their hypervisor for LPARs and what they called micro-LPARs at the time was astonishingly good. It provided very nice granularity and control for running multiple LPARs. An LPAR is like a VM, but is closer to bare-metal than what you find in an Intel environment. You had to allocate at least 1/10th of a virtual processor per LPAR. They had something called 'entitled capa…

LPARs -- "Logical Partitions"

I know the industry is full of technical jargon, but IBM is its own universe that pre-dates all of it.

Are LPARs like virtual machines, or like FreeBSD jails (which are like Docker containers, I think)? I get the impression that LPARs are full virtual machines -- each one could be running a different kernel as well as userland.

LPARs are like full VMs on POWER/AIX, they run atop the Power VM hypervisor

It's more like virtual machines. You had to use PowerVM, which would take care of virtual I/O, memory, cpu and network. You were able to split in micro partitions and do live partition migrations. In those LPARs you could then use WPARs, which was more like FreeBSD Jails and Solaris Zones. You had two options for it: application wpars and system wpars. I've used AIX[with all hw ecosystem] for many years as a main driver in a bank, and it was ahead of everything else in the market. Still brings good memories - loved it.
