Show HN: GentleOS – A pair of hobby OSes for vintage 32-bit and 16-bit PCs(github.com)
Hello HN,

I've been working on a simple OS for tinkering and running bare metal apps on vintage PCs.

Since I couldn't quite decide whether to target pure 16-bit, or slightly more capable 32-bit machines, I ended up with two separate versions:

- GentleOS/32 (https://github.com/luke8086/gentleos32) works on i386+, requires 4MB of RAM and VGA display supporting 640x480x16 mode or any 256-color VESA mode.

- GentleOS/16 (https://github.com/luke8086/gentleos) works on 80186+, requires less than 192KB of RAM and a CGA display supporting 320x200x4 mode.

You can find more details in the repos.

Ahh the Librettos... I had a couple of 50s at one point, one of those looks cool unusable thing and the brittle plastic damn, I opened it and the hinge snapped lmao my heart my soul

Unusuable because of how small the keys are

Am I crazy or are the "photos" generated? I did have T1800 and it never looked like this. It had a very early very bad grayscale LCD wiht fiddly contrast control, not a perfect crisp vibrant OLED like this page shows.

example how one looks like irl https://allegrolokalnie.pl/oferta/laptop-toshiba-t1800 https://www.youtube.com/watch?v=sxIc_UVKxvc

All the photos are real, though it took me *lots* of time to get them somewhat right. The display on T1800 is indeed "challenging". What helped was:

- Letting it warm for a while

- Putting windows in the right places, because each one generates its own artifacts

- Setting background to dark with the white pattern

- Fiddling with the contrast knob and matching it with the right viewing angle

- Using 2x zoom

To be fair, the default photo app of iPhone 16 automatically reduced some of the artifacts. The only post-processing done myself in GIMP was very basic stuff like adjusting white balance, exposure and contrast.

Here you can see a few very quick-n-dirty photos I just took for comparison - https://imgur.com/a/6Xz6vc8

Perhaps a new panel was retrofitted into it?

OLED panel? that would be a bigger hack than this OS :) Either all pictures are AI generated using QEMU templates that were there previously https://github.com/luke8086/gentleos32/commit/d40576226b7020... or those are real pictured beautified by AI. YT loves doing that to thumbnails, example https://hackaday.com/2026/06/03/hydraulic-drive-for-your-law...

The only AI-generated artifact is the cyberpunk wallpaper from the last photo, I'll admit that :)

Btw. the QEMU screenshots are still in the repo in https://github.com/luke8086/gentleos32/tree/main/doc/appimg

Love the photos of it running on 386/486 laptops. So cute!

What a lovely-looking OS! Also great to hear that the project isn't aiming for infinite changes!

Will be digging out some old hardware to test it out very soon, this is exciting!

This reminds me of the era when operating systems felt more approachable and visually distinct. Modern UIs are often cleaner, but many of them have lost some of the personality that older systems had.

That video's bullshit. People prefer old UIs because modern ui is shit, not because they're not creative.

Computer programs are tools. It doesnt do anyone any good if they're unusable in the name of chasing moronic trends.

I have a theory that corporations make new UIs to entertain people through them. First, to create the feeling that something is happening, and second, to increase screen time.

Old interfaces were far more practical for getting work done, and therefore obviously boring.

For me, as someone who is supposed to use technology as a tool and not as a source of amusement, the new interfaces of the major OSes feel unacceptable. But the other billion people chatting and scrolling are the real consumers, not me — and as a result, we now have the interfaces we have.

That’s one reason corporations make new UIs, yes, but the other is users demanding them for the sake of novelty. Reddit (but not only) is filled with people with no design sense complaining about how something which works (because it was relentlessly iterated on) looks “stale” and “old”. They’re the same users who jump from app to app willy nilly just chasing novelty. Any turd, if hyped enough, is ailed as “the future”, “modern”, “innovative”, which is repeated drivel from what the corporations tell you when they introduce their next thing.

Not really a theory.

Software makers treat UIs the way auto makers treat paint and body styling.

I think there's a couple of different forces at play in the convergence of GUI design that we're seeing in the past 20 years. First, there's been a huge amount of widely accepted research that shows what the most accessible way to design an interface is. Things like Google's Material Design and Apples Human Interface Guidelines come to mind. Second, the widespread availability of those two specific design guides make it increasingly common for developers to just create to those. It ensures that things just work and are increasingly portable. Third, we're in a landscape where API stability and design is prized. That's partially because of the number of times that design has been broken by updates and version changes. It takes many years for developers to update their applications when a new back-end is developed, and the time in between gives broken applications, and ugly looking fallback. You can look at running GTK1 apps on modern GNOME, or X11 apps rendering on Wayland over the past decade for an example of this.

All that said, I truly miss the days when we had interface skinning. There was a skin for OS X called UNO that was absolute perfection in my eyes, and it was ported to an old version of Android back when skinning was a thing. There's nothing like it available now. Even GNOME is highly against theming and skinning now, apparently because they like breaking with every single release rather than maintaining an API/ABI and skinning support. The themes that were available for Windows XP were so much fun, even if you had to swap out DLLs to get them working.

Focus-group based and UX research was a lot more intense in the 1990s compared to today, and late 1990s UIs are still among the best available.

Google's Material Design is fucking awful from an accessibility standpoint. There's no contrast. Clickable items don't look clickable. With a keyboard/remote, you can never tell what's selected.

Material is what made me hate google. It makes everything so difficult. It doesnt even look good. It's a low contrast sea of modern bullshit.

I sincerely hope that the material designers go to hell when they die and are forced to use their own garbage designs for all eternity while those of us who dont suck can use properly designed software.

I generally agree with you about UIs (if by shit you mean they've thrown away a ton of utility), but I don't think his video was bs, maybe just moved too far from it's original context.

Like almost all bullshit that is believable by a multitude, it is couched in some very small truths.

I don't really understand GP's message. User's comment history seems pretty normal, why would they drop a random IG link here? Wrong article?
LastTrain 7 hours ago|||
The link is to a designer talking about how technology has led us to a design world that is mostly driven by nostalgia. I personally don’t see it as being applicable here as it deals with big design houses not hobbies, but I can see why someone might think it is.
cestith 6 hours ago||
What a designer might call nostalgia an actual user of an OS might call standard, or maybe even intuitive. The point of an operating system is to be used. If it’s pretty, that’s a bonus. Usability by the target audience is the primary concern.

To anyone interested in the video, but without an Instagram account, gramsnap sometimes works. (Imginn.com sometimes works for viewing IG profiles.)

The video is a word salad of self-aggrandizement and judgement. Don't bother. The dude holds up fashion as if it is some paragon of virtue.

The first sentence of your comment seems to describe 99% of social media.
