World's worst video card? The exciting conclusion

Let's build a circuit that displays an image on a VGA monitor! In part 2, I talk about how VGA uses analog RGB signals to send different color pixels to the monitor. I use an EEPROM to store an image and build a simple digital-to-analog converter to generate the color signals to successfully display an image.

It's more like a cga. No DCA, and few bits on each line. I guess I haven't done those for 30 years... Hahahaha 🤣 (I was and graphics engineer).
@achtsekundenfurz7876 3 роки тому
I'd say something like the 16-color mode on the CGA, which was actually text mode, but drew no more than the top 1/4 of each character. The characters were either 220 or 221 IIRC (solid block left half. solid block right half), so that you could have 160 "pixels" per line: 80 characters, half foreground and half background color. Background couldn't be anything >7, which rendered some rather bright combinations impossible (like 15/9: white/sky-blue). The 100 lines rather than 200 were a limitation of the video RAM, which would have been too small for 200. More recently, there were hacks which sacrificed even more resolution on the CGA and used the characters 216 to 218 (25% foreground color, 50% foreground color, 75% foreground color) to dither in a 16-color mode. The results were "plasma" demo effects in text mode and a video player called "8088 Corruption" which ran on a 1981 IBM PC. And a demo called "8088 MPH" which ran on the same PC. All of these are on YT, and there's another video called "CGA doesn't suck THAT much!" or similar. Some of those examples are quite impressive.

@absalomdraconis 4 роки тому
With a bit of address mapping (take an address, use it to control a register, then use that register to provide the upper bits of an address when you try to access certain other addresses, called "banks"), and you can fairly easily overcome any memory restrictions. With multiple banks (two is good for moving data, three is good when also executing from "expanded" memory) you get a _very_ powerful system that's almost as fast as an un-banked system.

I noticed one of the sync wires isn't hooked up correctly I believe. On the second breadboard from the bottom, the white sync wire is hooked up to pin 13, which is an input of the flipflop. Whereas the yellow sync wire correctly is in pin 12. Could that cause the problem with the black bars or am I wrong somewhere?
@BenEater 4 роки тому
You're right, it looks like that was hooked up wrong! That would have made the horizontal sync pulse much narrower than it should be, which apparently the monitor was able to deal with just fine. Presumably I didn't notice it since it worked. But hooking it up to the correct pin which provides the longer correct pulse still gives you the black bars so I think my diagnosis of the slow ROM read time is still likely to be what's going on. Nice catch though.

Watching you explain this was the exact same to my brain as watching a speedrunner explain a complex glitch in a game I hadn't played yet. I wonder how many different things I could actually do if I gave them the proper amount of time and training. So much of what you were saying I have absolutely no idea but it's all incredibly contextual and represents concepts that can be applied in multiple alleys. Makes me think I should have more confidence in my abilities IRL. I mean the only thing that separates me from conquering that incredibly complex glitch is time and effort. I guess it's the same for the real world.

I have had multiple mind blown moments in this video but 23:03 and 23:23 i find very interesting as this seems to explain why graphics cards will tend to use the full VRAM clock frequency for a multiple monitor setup when each monitor is at a different refresh rate even if just idling on the desktop. Running the full VRAM clocks may be an overkill but at least now I understand 'why' this happens from this video. It is to avoid display artifacts! (Once I set the monitors to the same refresh rate the graphics card will allow the VRAM clocks to go to idle states as normal.) BTW Interesting use of the programed EEPROMs at the end there!!! 23:40

@CallumAi 4 роки тому
Unfortunately the worst case tACC for the EEPROM is 150ns, and the period of the 10MHz clock is 100ns, so using a D-type flip-flop (like the 74LS375) and correcting timing by one pixel would still have potential for a glitch. However, as he’s dividing the 10MHz by two by dropping the LSB of the horizontal counter, it would be possible to divide the clock to the D-type by two to produce a sampling period of 200ns and never violate the EEPROM access timing. H-sync would then also need to be delayed by two cycles rather than one.
@cbboegh 4 роки тому
I was immediately thinking the same thing - "you need a buffer on that slow ass prom". Ben's comment about sdram being faster and that this would solve the issue is misleading too. Let's say he used some low latency ddr4 with 15ns latency. That might work, but only because the monitor is too slow and likely samples towards the back end of each 25ns pixel. An old crt would shift the image by about a half pixel and if it was a good monitor, it would display the invalid data as vertical lines of pixel flicker. A 4k pixel is less than 2ns - so sdram is always buffered.

On the old BBC Micro you could move the start of video ram to any point including into the operating system memory. This was very interesting because you could watch, for example, the keyboard buffer filling up with the binary representations of the ASCII character you were actually typing. All sorts of other interesting things were visible because this is system memory and you can see all the data flying around the system. Its just a shame that's not possible with modern PCs.
