Strange... if it does, that's not my doing - it seems to work fine with the VPN I use, but I'll look into it. Thanks for the heads up.

That was one option I thought of at first (mentioned in the first section), but the info I found indicated that the /370 models used the same firmware as the "plain" 5170s - if there were any BIOS extensions, they were probab

Video footage of it running on real hardware: https://www.youtube.com/watch?v=BdM5j96tEpE Back when the demo was released, there were no emulators capable of running it all the way through. People are free to believe wha

It's not every day that an emulator author has to resort to analyzing bus-sniffer traces to debug and fix a demo effect - and certainly writeups that go into this level of detail are few and far between!

Yeah, I should think that's exactly what happened. I was a big AA user too, but at that point in time I wasn't aware of the Atari ST connection (and hadn't ever seen an ST), so whenever I spotted that font in a game I just t

Oh, gotcha - FWIW the fonts I labeled 'Verite' do come from Rendition Verite video BIOS charsets, but those in turn seem to be descended from the 'Phoenix VGA BIOS' type of font, or rather they're in the same loos

It definitely is. Pretty amazing what you can still find out about this stuff after all these years, now that we can cross-reference and search data so easily (and that collectors, preservationists, and emulator authors are still coming u

Thanks for those comments, much appreciated. I'm still planning future updates to that font collection, and I'll probably include straight-up binary dumps of the characters, so you won't have to jump through hoops to convert

It draws you a 'Golden IBM PC' - and then the screen goes "well green, anyway"! At least if you're running it on a monochrome board (where it evidently expects that you're using the green-screen 5151 monitor)

Yep, mentioned that in the intro to the article - recommended ++!

Fro me, it's things like comparing directories, filename search-and-replace/multi-rename, copying/syncing (locally or over ftp) with editable queues, etc.

Yes, and Area 5150 too :)

The author has done a superb job here. Not only does it have a cycle-exact Intel 8088 implementation (matched with disassembled microcode timings and hardware-verified) - it does the same for the CGA, where the dot clock is 3 times the CPU

A couple of GUIs written in assembly this century are MenuetOS and KolibriOS.

Yeah, that seemed to be the usage in most contemporary literature/magazines. There are also those other architectural factors like the bus width, the number of PICs, the keyboard subsystem and so on, which is why you could have "

Part of that was used for option ROMs like hard drive controllers, the EGA/VGA BIOS, network adapters, and for EMS; other areas were just marked by IBM as "reserved", which might have scared people off. In early machines the

I like to think that the original 5150 engineers would get it, but probably won't like it. "What in the nether hells are you doing with our respectable Business Machine?! Go play with an Atari!" ;-)

Ah, I think I get the original question now - you referred to the dynamic blending during the fade transitions, not to the static dithering used in the actual image data. If so, disregard my previous reply (see ajenner's instead). :)

Oh I certainly won't say that it was easy, mind you. The artwork was just done over a long, long period of time. As mentioned elsewhere in the comments, my 8088 MPH blog post from 2015 already shows an early version of one of the i

It doesn't really - for this particular technique an ANSI-art editor should do (and was in fact used for almost all graphics in this demo, to one degree or another). :) I suppose there's a wee bit of physics if you want to fine-tu

It should! Definitely runs on a 5160, and the 5155 is practically the same planar in a different enclosure.

by viler 4y ago
Yes, the 'Macrocom Method' section shows how it's done over the RGBI output, as used in this demo - the sample artwork shown there is in fact a much earlier version of one of the still images in Area 5150. :-) Although while

To me it seems like PC emulators tend to use the wrong approach with CGA. It's a fixed-frequency standard, so in principle it shouldn't be all that different from what you see in a typical emulator for the C64, Amstrad CPC etc.:

I maintain a static blog which is small-time enough, but I did want a comments section - essentially it's the only public way I have to interact with readers directly, since I'm not a fan of the whole social networking thing. E

Impressive work! Makes sense that this would require writing directly to the framebuffer - that was the oldschool way after all, and it's pretty cool to see this done on a modern device.

Cheers for the comments. I'm still improving and tweaking this script - planning to test a fully 16-bit-per-component version of the filter chain, to eliminate any artifacts that might still exist. (Also, halation/diffuse glow f

A lot of the differences people ascribe to CDs vs. LPs may not be due to the medium, but to different paradigms used when mastering audio for one or the other.
