Here's a revised version: "This demo, back in 1981, would have obliterated the market, wiping out Apple, Commodore, Tandy, and every other computer maker altogether. There would be no Amigas, no Atari STs, or any other computers-just the PC. Kudos to the team!"

The best CGA Graphics I have ever seen. I think some of them rivaled EGA or early VGA! It is clearly drawing with more colors than CGA originally was designed for (4-colors in graphics mode and 16 colors in text mode). Is this done with scanline swaps, by exploiting the ASCII Art text mode characters into custom ones, or does the CGA hardware have extra modes that were not documented, or ?
@docdordof5063
@docdordof5063 Ай бұрын
For those who want to really know: It's 640x200 16 color text mode, but it starts on a new line every other (or every) scanline depending on the part of the demo. Which means only the topmost line(s) of every character is ever actually shown. That way while it doesn't allow adressing each individual pixel with any color (thus why things like the marble in the marble madness homage has weird fuzz around it), you can still pass it off as "graphics" with clever artistry.

Honestly why is everyone ignoring the sound? This is the fucking speaker. Only way I can see that working is a straight DMA to the timer chip while another timer controls the DMA just to get all this smooth video. The 6850 also gives you insane control over the video and was designed with the idea that you could "add on" to it. Not that anyone did. Tech just moved to fast:P

You can play samples through the PC speaker using timed interrupts to send a series of frequencies that normally sets the pitch, but will actually ramp the voltage, similar to how samples are done with the C64 these days.

IIRC, the IBM CGA’s character set is set in ROM, which mean it is unable to be customized in any way. What they’re doing is tricking the CGA to only display two lines of each character, thus simulating 640x200 at 16 Colors. (Love your vids, btw!)

Astonishing. Back in early 1992, my old man brought a PC back from work, as they were chucking it out - an IBM XT with CGA display, two floppy drives, 512K of RAM and a broken hard drive. I was 12, and fascinated by it - but the blocky text, four colour display wasn't going to set the world alight (aside from a Breakout clone which had 16, much to my puzzlement, of course it was using the "160x100" trick). I still used it daily - as a games machine, of course, and eventually managed to find a copy of Windows 3.0 for it. It was unusably slow... you could see the window elements being drawn one by one, and it was in 640x200 mono only. The following year we bought a VGA card and monitor for it (not that Windows could use it, turns out the VGA driver has 80186 code in it), and I still remember how Prince of Persia went from looking awful to superb, and how sharp the text became. In late 1994 we bought a 486 and the poor old XT was given away to a friend. Seeing this 32 years on from those days, running on CGA... absolutely incredible. Not only figuring out the various tricks, but implementing them with that painfully slow hardware.... astonishing. A hearty "well done" to the talented coders, for pulling off the seemingly impossible. I can only imagine what the IBM folks would have made of this back in the day!
