ballyalley Posted November 26, 2017 Share Posted November 26, 2017 Is there any software for the Atari 8-bit home computers that creates color bars and other test patterns? I'm looking for software that can create at least an image that looks like (or is at least similar to) this pattern: Any other test patterns (like various crosshatches) would be a great bonus. There is software on the Atari 2600 that does this already; it's called Color Bar Generator: http://atariage.com/software_page.php?SoftwareLabelID=93 I plan to use the software with my Atari 130XE to test the following: 1) RF to TV 2) Composite to TV 3) S-video to TV 4) RF to demodulator to composite TV Any help finding software like this for my Atari is appreciated. Thanks! Adam Quote Link to comment Share on other sites More sharing options...

+mytek Posted November 26, 2017 Share Posted November 26, 2017 And there is a general one with quite a few different patterns that i posted over here: http://atariage.com/forums/topic/258702-new-development-gtia-in-cpld/page-31?do=findComment&comment=3887009 - Michael 1 Quote Link to comment Share on other sites More sharing options...

ballyalley Posted November 26, 2017 Author Share Posted November 26, 2017 I found this one. Hope its some use. http://gury.atari8.info/software/1678.php (Fixed link: http://ftp.pigwa.net/stuff/collections/holmes%20cd/Holmes%203/BELLCOM/051.ATR Thanks for the help finding some programs. I ended up using Color Bars from the Bellcom disk collection. I'll probably try the other programs at another time. I was able to get the colors adjusted to my satisfaction. I've been using this Toshiba 14" TV for years now. I never realized just how off that they were until today. I took four screenshots of how the TV looks with the corrected (at least to my eyes) settings. I should have taken some "before" pictures, but I didn't think to do that. There is an amazing amount of difference that you can see between the various connections: composite, s-video, RF and composite (via RF an Ambery RFDM2 to demodulator). These screenshots, taken with my Canon Powershot SX60 HS give an idea of the picture quality difference, but they don't really do the s-video output of the 130XE justice (that just looks beautiful in person!): Here is the Atari 130XE hooked up via composite: Even though s-video looks much better, I normally use composite video, as it allows for video artifacting. If I play any games that use artifacting to get more colors, then these games are B&W when using s-video output. Here is my system displaying via s-video: Here is the Atari 130XE hooked up via RF: Here is the composite output of my Atari hooked up using my Ambery RFDM2. The route the video takes is RF out of the Atari into the demodulator and then composite out of the demodulator into the TV: Thanks pointing me to this very useful color bar utility!

Adam Yes indeed. I think its between composite and s-video. Good test. Quote Link to comment Share on other sites More sharing options...
