Very true. A project I'm working on involves some scrolling and animation on older hardware at 60Hz. Looks absolutely smooth on the CRT, but when emulated on a modern display there's always some kind of trailing/blurring.

Yes - that's a great point. Although from the article, it seems that most of the latency isn't down to the display, but to the CPU/GPU part of the chain?

Yup, multisync/multi-scan sure complicates things. :) I'd still like to give it enough flexibility so that a preset can at least be accurate to a particular mode of operation. I actually went down the rabbit hole of looking up a

Thanks. Yep, a pure GPU approach is probably the way to go for this stuff in general. One reason I used FFmpeg here was the goal of applying the effect to stand-alone videos/images, which you can't conveniently/easily do wi

(Author of the script here): appreciate the observations. Pretty much all of these parameters (scanline intensity/sharpness, pixel blur, glow/halation, blackpoint for the background) can be adjusted to taste in the configuration

Outstanding work - never fails to amaze me when people unearth little secrets like that 4 decades after the fact. That MUL/IMUL/IDIV status bit hack is one for the ages.

Always wondered why a machine like the Archimedes didn't catch on quite like the Amiga did in the enthusiast/demoscene/etc. space. Both were certainly revolutionary for similar reasons. Was it the more limited reach outside

OK, then I think I get what you mean - scaling up the glyphs 2x and adding more bitmap detail, but perceptually sticking to the original shapes as closely as possible. That's something I thought of in the past but it proved trickier th

To sum it up (links to the various tools can be found at https://int10h.org/oldschool-pc-fonts/readme/#tools_used ): usually the starting point is some sort of raw bitmap data, which I convert to .png with somethin

My hunch is that this could be the result of subpixel antialiasing. It often creates a sort of fringing around the text, which ideally isn't very apparent... but it takes advantage of separate RGB components. Red text has only one comp

At the right sizes the included 'Mx' fonts should avoid those artifacts - they're ttf but contain embedded bitmaps, which seem to be better supported in Linux than in Windows (supported, but silly hacks required) or macOS (se

Yep! They seemed to be quite proud of it in the PPC-400 User's Guide. It goes on to describe the availability of various character attributes (reverse video, underlining, blinking, intensity) as "part of Corona's continuing

That's part of the reason I've added more fonts from more compatibles: some of them had much nicer ones - the Cordata and Wyse machines in particular more than doubled the resolution of the original IBM fonts, and indeed achieved

Hello HN! This project has been featured here in the past, and perhaps the new version would also be of interest. The goal of the collection is still the same: taking classic hardware/system charsets from pre-GUI IBM PCs and compatible

Thanks for the mention - I should note that there's a rather large update coming soon, with even more of them. :) There's also a bigger pile of system/bitmap fonts in raw binary format, included with my DOS-based font editor

'FontEdit' was also the name of a program published in PC Magazine eons ago, for creating VGA text-mode fonts in executable format. There were probably others that shared the name, but that's the one I actually remember typi

Thanks, appreciated! I'm planning an update soon - speaking of which, I might take a page from your own site with the custom scrollbars. :) AFAIK bitmapped fonts can be rendered in-browser, but only if they're installed on the ho

Impressive research work (and results)! I actually went through the same experimentation when I worked on the fonts and the website at https://int10h.org/oldschool-pc-fonts/ . I ended up with a slightly different solut
