HARMIK Posted January 17, 2010 Share Posted January 17, 2010 Here are some photos of the awesome job the Longhorn Engineer did for me on my 2600, with his deluxe service. Quote Link to comment Share on other sites More sharing options...
Longhorn Engineer Posted January 21, 2010 Author Share Posted January 21, 2010 (edited) Ok I need some help on the PAL mod. I sent the mod over to Preppie!! and he tested it out for me. Before I shipped it over I tested it on my little 2.5" NTSC/PAL LCD screen on composite and it worked fine. Wharfdale LY19T1CBW - Works Sony Bravia KDL 32D3000 - Works Loewe Concept L26 - S-video gave black and white picture only, somtimes there is a flash of colour, probably one frame every 60, nice sharp image though. I tried composite then but again only Black and White image (yes I checked the switch!) horrible verticle zig zag lines Sony 28" CRT - Black and white only with s-vid and composite Only thing I can think of is that the PAL signal for the color is slightly off spec which can cause it to misplace the color info on the TV or in the case of NTSC/PAL Tvs that the TV is defaulting to NTSC for some reason. Oh this PAL Atari is from Australia if I remember correctly. Any problem with it being in the UK?

GroovyBee Posted January 21, 2010 Share Posted January 21, 2010 Could it be the fact that the level for black is different for PAL and NTSC? Quote Link to comment Share on other sites More sharing options...
Longhorn Engineer Posted January 22, 2010 Author Share Posted January 22, 2010 I dunno, I found this and it seems people where having B/W issues with just the standard CD4050 mod http://www.atariage.com/forums/topic/128279-cd4050-av-mod-on-pal-atari-2600/ I am at a loss on whats going on.

GroovyBee Posted January 22, 2010 Share Posted January 22, 2010 The main problem is that its not the same person who made all the mods . Quote Link to comment Share on other sites More sharing options...

mimo Posted January 22, 2010 Share Posted January 22, 2010 I don't think the problem is with it being an ausie system. I think the different flavors of PAL are because the Audio is on a different frequency, this is a problem with RF, not AV Quote Link to comment Share on other sites More sharing options...
Ransom Posted January 24, 2010 Share Posted January 24, 2010 Installed the 7800 video mod today. The result is awesome! Great clarity and color in both 2600 and 7800 modes. It's just wonderful! Thank you, Longhorn Engineer! Quote Link to comment Share on other sites More sharing options...

Ordered from another source but they are taking there time getting to my place. Quote Link to comment Share on other sites More sharing options...
Longhorn Engineer Posted January 29, 2010 Author Share Posted January 29, 2010 Mods are shipping out again! Also I ordered a Easycap so I can record video of the mod in action and take screen shots without the camera messing things up. Quote Link to comment Share on other sites More sharing options...

That was pretty clever, Parker. xD Would be mad if it did happen in real-life Thanks! I am planning on building a simple portable in the future and film the entire thing. Tomorrow I will be uploading a "speed" Atari 2600 install on a 4 switcher. Quote Link to comment Share on other sites More sharing options...
CGQuarterly Posted January 31, 2010 Share Posted January 31, 2010 I just hooked up my 2600, which I hadn't played since last September, and I just have to say that I was re-blown away by the quality of this video mod. I play all of my other classic systems in RGB, and the quality of this s-video mod (on my monitor at least) is VERY close to RGB. So I just wanted to say thanks again. My VCS was previously AV modded using the Heckendorn method, and I'm glad I ripped that mod out of there and put this one in! I did notice that I can't play my VCS on my HDTV, which has an s-video input. It doesn't matter to me anyway because I have a dedicated gaming CRT, but is that a common problem?

It doesn't matter to me anyway because I have a dedicated gaming CRT, but is that a common problem? My HDTV doesn't like my modded Atari either. A few games generate a fuzzy B&W image while the majority don't display anything at all. Edited February 1, 2010 by SpiceWare Quote Link to comment Share on other sites More sharing options...
Longhorn Engineer Posted February 1, 2010 Author Share Posted February 1, 2010 Interesting what brand of TV are they? It should be working on HDTV's. Quote Link to comment Share on other sites More sharing options...
CGQuarterly Posted February 1, 2010 Share Posted February 1, 2010 Mine is an LG M237WD-PM 23. Basically nothing comes up on the screen. I think there were a few colored lines but I don't remember. It is a brand new TV so I didn't want to mess with it, and the Atari looks awesome on my gaming CRT so I didn't really care to investigate further.

+SpiceWare Posted February 1, 2010 Share Posted February 1, 2010 Mine's a 65" Mitsubishi Diamond from 2001. It doesn't like the signal put out by my Sega Nomad either. Possibly it doesn't like a 240p signal, or perhaps the Atari and Nomad put out an out-of-spec signal. Quote Link to comment Share on other sites More sharing options...

Possibly it doesn't like a 240p signal, or perhaps the Atari and Nomad put out an out-of-spec signal. My TV reads the Atari as a 480i signal. Hmm could be it doesn't like the weird scanline set up from the Atari. Quote Link to comment Share on other sites More sharing options...
+SpiceWare Posted February 2, 2010 Share Posted February 2, 2010 The Nomad is why I think it might be a 240p issue. I'll have to hook up something else to the TV to see. Problem is mom's been staying here and she's watching a lot of HGTV (yes, that's meant to be a G). She's moving to Trinidad (dad's already there working) at the end of the month - she stayed behind with the dogs until they are allowed into the country. She might be heading down to Corpus Christi to visit my sister later this week, if she does I'll test it then. I'm pretty sure my Vic 20 and Amiga CD32 output 240p.

Would be good if you could do a RF test with the Atari to. Quote Link to comment Share on other sites More sharing options...
SoundGammon Posted February 2, 2010 Share Posted February 2, 2010 ...ever try running the video through a vcr? Game to video in, video out to tv. Also, put a blank cassette in and hit record, that's when the vcr's own video circuits kick in, remember Macrovision? Quote Link to comment Share on other sites More sharing options...
