Impressive curation effort. One comment: at least a few of the examples in the gallery seem to be of the "last, greatest" version, which actually isn't necessarily the greatest, and definitely not the most interesting.

For example, the "Domain_OS SR10.4 - 01 VUE desktop" is a bit confusing, and may cause people to miss actual DomainOS.

Apollo DomainOS (or Domain/IX, or simply Domain) had many unique and interesting things about it, but disappeared soon after being acquired by HP. It looked more like it might look if you took a programmer who had mostly only seen text terminals, and gave them a megapixel display with pixel framebuffer, a mouse, and the freedom to design the keyboard hardware, and told them to make what they would want to use.

VUE (around when the Unix workstation vendors collaborated on standarding on a common desktop environment) was for HP-UX , which was a very different operating system, and entirely different user experience. More of an early attempt at let's give non-power-users an accessible computer with virtual desktops and everything.

Similarly, Solaris had innovative OpenWindows (including but not limited to a networkable display system based on PostScript) before they got the common desktop environment.

SunOS 4.x (retronym "Solaris 1.x") and earlier could run the earlier SunView environment, which was more like monochrome early Mac than the later Open Look look and feel of OpenWindows.

No Pick?

https://en.wikipedia.org/wiki/Pick_operating_system

My first actual job was working for a local health authority here in the UK, and they had a Pick computer running some database application thing, I think to do with accounting. I had to run the backups. Sorry to be a whinger, I don't mean to belittle the monumental amount of work.

  • patja 11 hours ago

    Similar experience here. I worked on an ERP system for a chemical distributor that ran on 5 Honeywell Ultimate systems distributed across the US. General ledger, order management, warehouse order pick lists, chemical recipes, MSDS data, inventory, etc. We synced database updates every night, and once a month someone had to spend the night in the datacenter swapping 9 track tapes for backups.

    I loved working in Pick BASIC on those systems. So much you could do with "dict items"

    Ha. My first SW job interview was for a programmer on a Pick system at some small company in Manhattan. I think they were involved in publishing or something. Anyway, the salary they offered was so pitifully low all I could do was politely decline. Was too young to even know that I could negotiate.

I hadn't realized Domain/OS emulation was viable these days. It's one of the few systems that has actually "lost" features - the terminal-window-like thing (called pads, I think?) when in line mode had a dividing line at the bottom where your unconsumed typeahead was visible and you could continue to edit it until it got read - not just one line, the entire unconsumed input. (Not that it's a particularly desirable feature - it's just one that I'm pretty sure you can't implement with ptys...)

    Unfortunately, pre-Domain/OS AEGIS is basically lost. One person popped up with talk of imaging their 9.6 floppies, but I haven't seen anything since then.

      I just received from a retired engineer, a binder of 8” floppies that says Jan 1984, AEGIS 6.0 / Mentor 3.0, Full Backup, WBAK. The owner got them from a dumpster 40 years ago, but suspects someone just reused the binder to store blank floppies. Anyhow I’m working on it.

      I’ve also found source for an AEGIS menu system (mouse, hotkeys) written in Forth.

      • em-bee 3 hours ago

        it's probably not old enough, but in the mid 90s i acquired a working apollo domain workstation that was functioning as a doorstop at a university library. it came with a full set of documentation, but no floppies, i think. i don't know which version, and i don't know if it is still working now. it's gathering dust at my mothers home in europe.

    • neilv 11 hours ago

      I wonder whether this could still pop up at estate sales, or when a retiree is cleaning out their garage.

      Not all gear got junked. When I was a teen intern, I got some obsolete Apollos (and 2 logic analyzers and a terminal) from my employer, and other people were also bringing home gear the company "sold" them.

      Somewhere, there might well be an industry or university sysadmin or programmer who brought home a box of old QIC tapes, and one of them says "AEGIS" on the label, and it's in a garage/attic.

      Also, rumor has it that at one point Boeing physically archived at least one Apollo network, because they apparently take documentation integrity extremely seriously. If that's true, they might have an engineering librarian or someone who could take an interest in making sure any versions of Aegis/Domain they need (and have preserved media for) can run on emulators or something?

    • andreww591OP 7 hours ago

      Yeah, I'd definitely like to see older versions of AEGIS as well

  • andreww591OP 7 hours ago

    Yeah, MAME has had working Apollo emulation since around 2010. Domain/OS is definitely pretty odd. You could almost mistake SR10 for a normal functional Unix if you use the SysV or BSD universes rather than the AEGIS one, but while it is clearly Unix-like, it's also quite Multics-like as well and is pretty distinct from the typical functional Unix family.

  • jerf 9 hours ago

    Not only can you implement that with PTYs, it's how they operate by default. That's why you can telnet to an HTTP server and make a mistake and use backspace to fix it. The terminal will only send lines over. You have to use a command to put it into "raw" mode so the application gets every keystroke immediately. You have to ask for your PTY to not work that way.

  • compsciphd 13 hours ago

    why could you not implement it as ptys.

    Currently the terminal doesn't really process input itself, it just gives the program running the "raw" fd.

    If instead the terminal gave the processes a pipe (for instance) and consumed all the pty input itself (and its end of the pipe being a buffer of that content), why wouldn't it be the same?

  • kmoser 10 hours ago

    It took me a few minutes to determine that this is basically software that one can download, not a website that showcases screenshots from all those OSes. A search feature would be great, or even just a text list of all included OSes.

    I'm also wondering whether/how they include OSes from devices that VICE already emulates, since that could save some work if they want to include OSes of Commodore devices.

    I hope so, and also that it is a plain black-and-white list.

    • VLM 12 hours ago

      I can't figure out how to find a list and I believe that's intentional to avoid simplistic copyright search and takedown type of problems. It is aggravating how little information is available on the website.

      1) I run my own systems in emulation and its always educational to see how other people handle configuration and sysadmin type problems. Much like programmers reading other programmer's code for educational purposes.

      2) I have a genuine philosophical question which it appears I cannot answer by any means simpler than running it and trying it. Similar to the halting problem LOL. I wonder how the project handles operating systems like MVS/360 where there exists a perfectly good 1960s installation (which I have installed by hand from tape for the experience) however no one uses that IRL because the various MVS Turnkey projects provide seemingly infinite debugged and dependency organized patch sets. There's quite a difference between trying to white knuckle a homemade bare basic MVS/360 from the 1960s vs "MVS Turnkey 4" which basically just works out of the box.

      Another example of #2 above is there's DEC PDP-8 OS-8 which technically boots... but the most common distro had a non-working but trivially fixable FORTRAN compiler (IIRC the runtime package filename was wrong or something similar). There's a lot of fun customization.

      Another example of #2 above is I wonder how the author handles RSX-11M, distribute the ancient unpatched unmodified OS from DEC or ship something like the Billquist distro, or does the author ship the PiDP-11 RSX-11M (or is PiDP-11 shipping the Billquist RSX-11 distro now?)

      I guess for people not into retrocomputing it would be like claiming some rando RedHat .iso from the 90s is "The" Linux operating system. Well, its "a" linux from one instant in time... Likewise there seems to be no "The" MVS/360 operating system there's a zillion possible local installs of all capability levels and eras, all very different and fun.

jonnyasmar 7 hours ago

What I find interesting about projects like this is how much of the OS "feel" doesn't survive emulation. The visual layer comes through fine, but the things that actually defined the experience — keyboard click latency, the specific mouse acceleration curves of period hardware, the way a CRT scanline gave System 7 fonts a totally different texture than a sharp LCD does, the audible click-thunk of Atari ST or early Mac dialogs — none of that gets preserved.

Run System 7 in an emulator and the menus look right, but the input feels wrong. What we're really preserving in these collections is the screen output, not the interaction. Which is fine for an archive — just worth being honest it's a museum of appearances, not of use.

  • bitwize 2 hours ago

    I tend to associate the Amiga with razor-sharp interlaced displays, so seeing 640x400 noninterlaced in an emulator leaves something missing. The Amiga also had an unusually smooth mouse response due to its interrupt prioritization and use of hardware sprites for the mouse cursor. I had never seen a mouse move as buttery-smooth as it did on the Amiga. Again, this is not captured via emulation; not even my MiSTer seems to get it right.

This triggered a rabbit hole search that had me rediscover Packard Bell Navigator[1]. The nostalgia and joy this page brings me is hard to describe. I hope everyone remembers their formative tech journey so fondly.

1: https://en.wikipedia.org/wiki/Packard_Bell_Navigator

  • jolmg an hour ago

    > Packard Bell Navigator is an alternative shell for the Windows 3.1 and Windows 95 operating systems

    Huh. I thought the term "shell" generally referred to command line interfaces to the OS and that Unity's way of describing itself as a graphical shell was some "new" (2011) generalization of the term, but I guess there is at least this precedent for using the word like that.

  • mrandish 6 hours ago

    I vaguely remember using that UI. It's in that strange category of preset graphical menu launchers that were a bit more than an autoexec shell menu but much less than an OS. File it under "ideas that seemed like they might be good in concept... but were too limited in practice."

    I think I got it on an early Packard Bell Pentium system in 1994. I remember I used it even though it sucked because it seemed a little better than Windows 3.1 mostly due to the fact it didn't try to look like a functional windowing operating system. Once I got my hands on Win95 beta, I never ran it again. Of course, early Win95 also sucked as a real OS but it was enough better than Win 3.1 that I could slowly begin to transition off my beloved Amiga 2500.

    Oh, this made me dig up a memory: What was that skeuomorphic music player Packard Bell would bundle with Windows 3.1? It looked like a stack of stereo equipment with a CD player, MIDI player and wav player/recorder. When I was a kid I loved how it looked like a stereo system and grabbed a copy from a friend. I also remember being greatly disappointing when it would not run on Windows 95.

    • andreww591OP 7 hours ago

      That was Voyetra Audiostation, and I definitely remember having it on the Packard Bell 486 that was my family's first computer (which was already obsolete when we got it, since we got the cheapest machine they had; it was on clearance sale). While I do have Windows 3.10 and 3.11 for Workgroups images, I don't (yet) have one with Audiostation. I have sometimes thought about trying to find the closest PB master CD ISO to the one that came with that machine and install it, but just haven't gotten around to doing that yet (still got lots of other stuff to install).

nlitsme 14 hours ago

quite a decent collection. and actual working osses.

one that i noticed missing: Novell Netware, I spent several years in de 90s developing software for it. It was the main office network server software on those days.

3.x, 4.x ran on relatively regular 32-bit PC server hardware. 2.x ran on the 80286 in protected mode, the only OS I know which did that.

Copies can be found at archive.org.

  • andreww591OP 6 hours ago

    NetWare 4.11 and 6.5 are included, but just don't have any screenshots on the site (the screenshots are not exhaustive at all and just a small sampling of what's there).

    And even though there weren't very many 286 protected-mode OSes there were still several of them, with the OS museum including:

    1B/V3 (a Japanese OS with an object-oriented desktop and extensive compound document support, part of the TRON project) Microport SysV/AT Prologue TwinServer (an obscure French OS that originated on 8080/Z80) Multiple versions of OS/2 1.x QNX 2.21 QNX 4.0 IBM PC XENIX

    1B and TwinServer are especially notable since they were maintained as 286 OSes long after x86-32 machines had made 286 machines completely obsolete; the last versions apparently being in 1997 for 1B and 2002 for TwinServer (although the last version of TwinServer has some limited support for 32-bit code, it can still run on a 286)

  • whartung 11 hours ago

    Mind, I never used Netware.

    But, originally wasn't it mostly a network system to support network printers and file systems?

    BTRIEVE would run on top of that. But, as I understand it, Netware wasn't required. They just went together really well.

    Finally, especially with Netware 386, they supported "NLMs". "Netware Loadable Modules". This was what let you deploy applications to the network server. Some databases ported to that I believe. I think Informix had a NLM version of Informix OnLine.

    So, to me, early Netware seemed more an interesting network utility more so than what I, at least, would consider an "OS". Perhaps it was an OS, but just sealed off. At least until NLMs arrived, making the system more extensible.

    I have no idea what facilities were available to NLMs, or how they were developed.

    • davidgnz 11 hours ago

      I think NLMs are effectively kernel modules. No memory protection, and only cooperative multitasking. So I doubt there were much in the way of limits on what an NLM could do.

      I think they were usually developed in C. Metrowerks had a compiler that could build them, and Open Watcom can still do so as well.

Is there a proper full list without needing to download the very big ZIP archive file?

I don't know if it includes "every operating system I can think of". I can think of some things: TempleOS, BTRON (there might be more than one implementation; I know of an (apparently) abandoned FOSS implementation), Serenity OS, and some others that I do not remember what they are called.

Also, what might be useful for preservation is, in addition to the files and emulation, also the documentation for programming those operating systems. There would also be such a thing of consideration as documentation of old computers (including their instruction sets), which might be a separate project but potentially might be useful in combination with this.

Another thing would be somehow you can download individual systems together with information about the emulation, in case you want to use your own emulators for it instead of installing an existing collection with its own installers and launchers etc.

Some people mention uncommon features (and features that work in an unusual way). I think that would be worth making a article about too, and just because a feature is common does not necessarily make it good.

  • andreww591OP 5 hours ago

    I haven't yet included a full list, but I guess I could include one.

    All of those OSes you mentioned are included. BTRON isn't a single OS, but a small family of OSes based on a common specification (just like Unix is); the OS museum includes the demo 1B/V3 and Chokanji 4. The FOSS BTRON implementation you're thinking of is almost certainly B-free/EOTA, which is also included. EOTA never actually implemented BTRON proper before it got abandoned. It basically just ended up being like a Unix based on an ITRON kernel.

    Documentation for some OSes is included, although I've focused more on user/administrator documentation over developer documentation. It would probably be a good idea to include developer documentation though.

    I've thought about making individual images available for download, but many of them are dependent on particular emulator versions and/or the common launch scripts so it isn't quite that simple.

Pardon a simple question - this implies nested virtualization, or is the second step emulation?

The download is a Linux VM, gotcha.

Are other OS-s nested virtual machines inside that Linux VM, or emulators (in which case, holly mackerel, that is even more impressive :O... and also why??).

Readme seems to imply it's emulators, but it also uses the words "virtual/virtualization" or "VM images" liberally sprinkled.

    I imagine the author's using OpenSIMH (https://opensimh.org) or something similar, so it'd be an emulated CPU running the userlands.

    I have a container that runs a 4.3 BSD userland using opensimh; it's not super hard to set up, just takes a bit of patience and willingness to learn how opensimh works.

    • andreww591OP 6 hours ago

      Several different SIMH forks are included, along with a lot of other emulators; there are well over 150 different emulators, with some having multiple versions and variants present to handle things like regressions related to specific OSes.

      Nested virtualization for certain x86 OSes running in QEMU is supported, although you will have to enable it manually (VirtualBox has a checkbox for this in its settings). For VMs that support it, the QEMU launch scripts will automatically use KVM if available and fall back to TCG if nested virtualization isn't enabled.

d3Xt3r 6 hours ago

Would've been cooler if the emulator was implemented within the browser itself, lke DistroSea, or Archive.org.

  • andreww591OP 5 hours ago

    I wish I could do that, but there are a lot of emulators that don't have web versions, and the launcher and related scripts are very heavily dependent on a Unix-like OS and there is no way to port them to JS (a completely separate launcher and scripts would have to be written).

    It sucks that there's no good way to port Linux directly to WASM UML-style, since WASM insists on implementing memory safety at the bytecode level with no way to bypass it. There is a very limited port, but it doesn't support paging. Not all the emulators would run on a full-featured WASM port if one existed, but that could be dealt with by just using user-mode QEMU to run whichever ones are x86-only.

  • ForOldHack an hour ago

    Although Emacs commonly refers to an editor, It was always so very much more: It is a compiler, an editor, a pain-in-the-arse, one of the most brilliant uses of the blurring of the layers of App/os/hardware. Its a lisp editor, a lisp development environment, a lisp machine, an OS, Its a database, a word processor, a calculator... the only things in computer science that It is not is a spread sheet, and a paint program, but do not say that too loud or someone will write a macro for it that does both of these things, in some weird way, you will have visions of Phillip K. Dick.

Just a couple of years ago I worked for a client who had a computer with Solaris 2.x running. It was quite a critical piece in the system.

I'd love to go back to the 90s and live it again.

    A Mister does a good job of recreating period appropriate load times and quirks. You can put it in whatever old computer case you're most nostalgic for, connect an old CRT monitor and most peripherals should have some USB converter if necessary.

I don't see TempleOS here unfortunately https://gitlab.com/virtualosmuseum/virtualosmuseum/-/blob/ma...

  • andreww591OP 6 hours ago

    The last version of TempleOS is included, but I installed it myself, and I didn't bother to include most of the images that I just installed by myself in the credits.

    I'm also planning to add earlier versions as well as the later forks at some point.

Hug of death? Error code 522 on downloads.

kramit1288 13 hours ago

quite impressive, how did you collected? just find images online or you actually have all of these OS.

  • andreww591OP 6 hours ago

    The vast majority were downloaded. A few I got when I exchanged compilation DVDs with someone in Finland in 2006 and 2009 (I uploaded the images on those to BetaArchive back then and they've made their way onto various other sites). The only ones that I have that were installed from images I dumped from original media that hadn't been previously shared were LynxOS 4.0 and MaxOS Linux (not to be confused with macOS, it was an obscure early-2000s commercial Slackware fork from a company that was semi-local to me; the CD was given to me back then by somebody at a long-defunct local computer store).

TENEX and TOPS-20 would be nice

  • andreww591OP 6 hours ago

    TOPS-20 4.1 and 7.1 are both included.

    I'm not aware of any fully working TENEX images unfortunately. There are partial images, but last time I checked they weren't in a state that was even remotely usable.

  • iberator 13 hours ago

    tops20 is avalible to use at sdf.org :)

Where's Microsoft Bob?

  • Someone 12 hours ago

    That wasn’t an operating system. https://en.wikipedia.org/wiki/Microsoft_Bob:

    “Microsoft Bob was a Microsoft software product intended to provide a more user-friendly interface for the Windows 3.1, Windows 95 and Windows NT operating systems, supplanting the Windows Program Manager.“

Wow. That was a bit of nostalgia, just to read some of the names.

  • juvoly 15 hours ago

    Yeah! Browsing through the screenshots truly feels like watching vintage porn.

      You can only view the operating system, you can't view those websites again, haha.

Is TempleOS in here?

anthk 11 hours ago

HeliOS and transputers is one of the most interesting systems ever; if you use Golang and/or know 9front and concurrency you'll be at home, because it was concurrent and multicore literally by design where the CPU 'cores' synced themselves with messages.

https://www.atarimagazines.com/startv4n4/transputer.html

They were pretty much ahead of time with multiprocessing.

  • andreww591OP 5 hours ago

    Helios unfortunately isn't yet included. Last time I checked the Transputer emulator doesn't support the special Helios I/O server protocol, which is different from the one that the usual occam software used. It's on my long list of emulators/OSes to fix/finish though.

Very neat to see this project come to completion Andreww.

Are there any any operating systems that you'd like to add to the collection but haven't been able to find?

Maybe someone here at HN could help with that.
