The original composite color video for the Atari and Commodore systems (others?) had a basic problem: The analog composite monitor screen pixels were not divided up into multiples of 8-bit bytes as is standard on 8-bit and higher computers. I think that they used a 65-bit-code value when translated to the digital computer video circuitry creating the video image. The video chips for these early home computers were mostly made with a 64-bit code -- slicing off that "pesky" extra bit, which would have required extra and more-expensive circuity in the video chips to handle (perhaps major ignorance/hubris of a digital person about that "old fashioned" analog stuff). This one-bit difference, until eventually understood and corrected, meant that a rainbow rippling color -- caused by a Moire pattern beat-frequency effect of 65/64 repetitions of the error -- was superimposed on the desired image, as well as creating fringing around the borders of discrete image blocks (letters, graphic symbols, etc.) on the screen. This problem was quite evident in your Atari example when you switched white/grey letters from composite with the problem to RGB without it in the video. It was amazing how long it took for computer design people to realize that the person who created the 64-bit-based video chip circuitry had not realized (or maybe cared) how much of a difference that one bit would make and cut it off for "efficiency" (or maybe just ignorance/error) -- you cannot do that with things that use analog or wave-based (video, for example) emulations!

And all these year I used to PREACH THE VIRTUE OF S-VIDEO! When true RGB was available all along. I always thought the TV menu interface looked sharp and clear in an uncanny way.

And I thought I was slick because I had a little 13" Sharp television, and that my NES looked great on it...now I know there's a better option! This is mind-bendingly amazing!

Just wondering, how would sync-on-green work with this? Can you just use an RCA splitter between the green and sync input? Also I read online that using a 75 ohm resistor and/or a 220 microfarad capacitor on each of the Genesis' RGB lines improves the image clarity (I'm gonna need someone to confirm this)

8-Bit Guy, I have a question. Please help. I'm trying to use a video capture device with a new laptop. I've had quite a bit of experience with video capture cards being a schmerz in den arsch. It's not working with the new laptop. I'm getting a green preview screen in the software. Is this simply a compatibility issue with this particular laptop?

My question is my Sanyo AVM-1307 tv has microchips blanking on B to the jungle chip. Since I can't post a picture here is the pin out I found. Micro ctrlr chip pins: 41/AV (unused), 21: R, 22: G, 23: B, 12: 5V+, 24: BLK (which is connected to B). Micro Ctrlr chip: LC864616A Jungle chip pins 15: R, 16: G, 17: B/BLK, 14 VCC(+) <video> [maybe composite], GND 37, IF GND: 7, IF VCC: 11 How do I connect composite/sync to this? And does IF need to be tinkered with as well?

Does composite work better for NTSC than it does for PAL? when you switch back and forth between RGB and Composite, I notice a lot less 'dot crawl' on your reds than I do when I use Composite.

I hate to be that guy...no actually it's kinda fun. Analog TV does exist here in the US. we still get 1 analog station here in southern Utah. I don't know why they broadcast it but it does exist. It's some really lame channel. I haven't even checked it out other than noticing an old John Wayne movie.

When I connected a PC same way, I had 5 Volts from the PC so blank signal appeared as soon as the PC is turned On. BTW there is 5V pin in any VGA for this purpose. :)

Back in 1998 I had secondary PC, 486 based. It had no monitor so I connected it to the old Soviet TV via RGB from it's VGA card. Yes, I had some VGA-to-TV drivers, but Quake 1 was running AWESOME on TV at 320*200 resolution, with no squares pixels, because it was 'native' resolution for TV. It was like a hardware smoothing for the picture :) This PC was connected to main Pentium-166 via COM-port and we played multiplayer game Quake via null-modem cable! That was really great experience at that time!

i spent most of the video wondering why for a teky guy crt RGB mod feels like new discovery when most of the stuff we owned had RGB and at the end he sais "America" . nuf said ... also woundn't it be easier to get a control board with rgb from internet shipped ? our crts (funny enough) had ntsc also . really enjoying your videos.

I know you address this but if i had to mod a tv. Id use the scart or bnc brake out connectors since i have a few of those for my old consoles. Fortunately i have a newer crt (still 480i tube not hd) that has component inputs so id just need a transcoder.

It doesn't surprise me that a lot of people didn't know this could be done. Does anyone remember seeing big screen TV's in the arcade. Well some were rgb, but some were actually regular TV's with a tuner. There was a composite sync connector on on the back and in many cases a color amp chip that fed the rgb lines to a point on the board. None of this was rocket science, after all a computer monitor and a TV are very similar aside from the scan frequencies. It would also surprise many that in the early days a lot of arcade monitors were actually regular TV's with the tuner stripped out. This video further shows how much ignorance in the world there has been towards CRT's being automatic junk once digital broadcast came out. A long as you touch up solder joints replace failing caps, and keep the dust bunnies out they will last a long time.

Wouldn't that be an ironic thing if that header was for direct RGB control at the factory when testing the RGB signal... Probably was, to be honest.

VideoNOLA (19 days ago)
As I recall, my Laser128 (Apple //c clone) could send out both analog RGB and composite (RCA) video. Ironic, since the ][+, ][e, and //c were only engineered to be connected to composite monitors (many of which were MONOCHROME at the time -- amber or green), thus few software titles took the distinction into account. But it did mean I could ditch one of my CRT screens for a dual-input model to serve as the display for two different computers.

I have an old 13" Sony Trinitron monitor, the kind used to watch video. It has the standard composite video IN and an RGB video IN. I would like to use it to display an image from a VGA laptop. Maybe something like a bunch of scrolling green text with a Matrix feel to it, or better yet some Blade Runner basic language text. I have tried to use a VGA to RGB patch cord but it doesn't seem to work. Any ideas?
Auberge79 (12 days ago)
No composite video output from the laptop? Then you'll need to make your VGA to give out TV standard frequencies. Yet you'll need a VGA cable soldered to RGB input of your TV. But I am pretty sure you'll not be able to run any windows later than win98 with VGA-TO-TV drivers.
MocnyBrowarek (21 days ago)
I have modded a lot of Sega MegaDrive consoles (Genesis) from my experience the early models (with superior sound) had not so great RGB output (jailbars, rainbowbanding etc). I'm moding all those consoles with S-Video witch is superior for those consoles as it's just as sharp and clear but without all those problems. Same for the early 2 chip SNES consoles - they have very bad RBG (just a little bit better than composhite), so adding S-Video to them gives MUCH superior image quality. Now I didn't mod any CRT TV with RGB/S-Video, because all european TV of the time have RGB already and all my TVs have S-Video but I did some research and it would be much easier and faster to just add S-Video input to some random tv sets ot the time, because all of them have chroma and luma legs on their main chips.
Aaron Smith (21 days ago)
something I noticed about your TV which I don't know if it's relevant but the composite port on the back looks like a SCART is it possible you could just easily disorder that port and put a SCART port on

Lance Page (27 days ago)
Great video. What I would like to see is a hack that puts a VGA input onto a digital chassis crt TV. Simply because where I live I seem to only find these 100hz jobs. I know it can be done. This would by pass all the digital processing before the analogue input signal of these era tvs. Because they are basically glorified computer monitors that run a 15khz analogue signal, then the digital chassis run natively at 31khz and converts it back to 15khz - so it can run "100hz". This was the last step of manufacturing tv before the advent of digital broadcast and LCD screen TVs as we know them today. I would even say these digital chassis consumer crt TV are more common these days than standard analogue TV.

I had an EGS Spectrum for the Commodore Amiga when it came out. I worked in a TV station and had access to the books for the NTSC standard. I took note of all of the frequencies and built a cable from 15 pin VGA to the Commodore 1084S DIN connector. I set up a monitor profile with all of the values, and to my amazement , it worked!

Nicely done. I'm definitely not going to attempt this... opening a CRT runs the risk of electrocution, and it's not a risk I want to take. But hey, you're a professional... you know what you're doing! There are a small handful of monitors and televisions in the United States with SCART connectors... I've personally got a Samsung 910MP with the port on the back (but you have to set the monitor to the European territory to make it work). I wasn't thrilled with the quality, but it might have been a problem with that specific display. My question is this... is there a way to connect a game system like the Genesis to the VGA port on the backs of more modern displays? I mean, if it's just RGB you'd think it would be possible.

konatadesuka (1 month ago)
>takes cover off >slight bit of dust in there >red anode 25KV high voltage wire is still red I could say you haven't used that TV very much, it is literally clean inside. With a console like the original Playstation, an RGB, even an S-Video connection brings new life to games compared to composite. Also, that mod unfortunately does not work in the latest televisions as they only have one chip. Granted, most support Component which looks like it is a solution but it is not RGB. Another interesting mod is making an RGB to component (Y/Pb/Pr) adaptor board and using it on today's LCD televisions that still come with that analog input.

You are right, we're spoiled here in Europe. Pretty much any Tv set made since the early 1990s has RGB on the scart connector. I noticed that your set has even a SCART- shaped cutout on the back panel where there are the Audio and video RCA connectors mounted on a black plastic rectangle on the mainboard in lieu. I keep finding sets like this on the street and nine times out of ten, they work fine. The remainder tend to have cracked solder joints on - you've guessed it - the SCART socket! They almost certainly got dumped when the signal from the digital set top box went intermittent and the owner went out and bought a new LCD monstrosity. Broken plastic front panel control buttons are another common problem. A very small number have more serious problems like Line output stage failure.

6:00 I don't understand why you add resistor in series with the original resisters but not in parallel, and maybe this is the reason that your controller become dimmer than before.
