rednakes1 Posted November 21, 2016 Share Posted November 21, 2016 What I meant was that I was comparing the picture with the original TIA in my modded unit to the picture with the new TIA in the same modded unit. So the picture in the same Atari was affected by just changing the TIA (and RIOT). Quote Link to comment Share on other sites More sharing options...

No wonder I couldn't find any on eBay; I was searching for "Atari 6532" all this time, not the part number on its own. Quote Link to comment Share on other sites More sharing options...

That one was an "off the shelf" component. I had a 6er once that had vertical shadows on the score numbers and the fonts just didn't look right. Swapping in one of these fixed it. 1 Quote Link to comment Share on other sites More sharing options...

There are others that are "New" though. Not sure if I want to get one or buy a set of 5 and play lottery. Quote Link to comment Share on other sites More sharing options...

These vertical shadows are like the jailbar lines we're describing or something else? Quote Link to comment Share on other sites More sharing options...
rednakes1 Posted November 21, 2016 Share Posted November 21, 2016 I see "shadows" or blurry edges on the scores of some games and also on the missile launchers in Missile Command. Quote Link to comment Share on other sites More sharing options...
zylon Posted November 21, 2016 Share Posted November 21, 2016 These vertical shadows are like the jailbar lines we're describing or something else? Not sure as it was long ago. The scores appeared almost in an older font style than they should have with vertical black shadows on the right side of each digit. Unfortunately, I did not snap a picture of this display. I do remember using Missile Command to test it afterwards. Quote Link to comment Share on other sites More sharing options...

Not sure if I want to get one or buy a set of 5 and play lottery. I had just linked the first one I found running a simple 6532 IC search on evilbay. Someone else on here did buy a lot of 5 and it turned out to be a good thing as the first one he tried was bad. The other 4 worked fine.

AtariLeaf Posted November 21, 2016 Author Share Posted November 21, 2016 Okay, ordered a set of 5 "new" 6532s from Hong Kong. One long month of waiting I might have to as well. I have several sixers both heavy and light with the same issue. Riots all going all of a sudden? Seems odd Quote Link to comment Share on other sites More sharing options...
zylon Posted November 21, 2016 Share Posted November 21, 2016 Something like this? Kind of, except on mine the points on top and bottom of the 1 were missing. Quote Link to comment Share on other sites More sharing options...
AtariLeaf Posted November 21, 2016 Author Share Posted November 21, 2016 I pulled out another sears light sixer that I haven't tried in a long time - no lines. So the RIOT could be the culprit? Without opening these up, are the sixers generally socketed boards? Quote Link to comment Share on other sites More sharing options...

Without opening these up, are the sixers generally socketed boards? Maybe we can compare the schematic for the sixer and 4-switch to see what could be causing it (Eg. A different capacitor somewhere?). My non-modded Atari Jr. doesn't show vertical lines either. Quote Link to comment Share on other sites More sharing options...
AtariLeaf Posted November 21, 2016 Author Share Posted November 21, 2016 Thanks for the link. My question is, after researching failure symptoms for the RIOT, these vertical jailbar lines are not one I've seen mentioned when it comes to a bad RIOT chip. (Ok that's not a question, more an observation) I thought the TIA would have more to do with graphical issues, no? Quote Link to comment Share on other sites More sharing options...
rednakes1 Posted November 21, 2016 Share Posted November 21, 2016 One observation I made just now is that my Jr. Has the CD4050 chip on the lower right. Not sure if that helps in anything, but I thought it helped in synchronizing the video signals? Quote Link to comment Share on other sites More sharing options...
zylon Posted November 21, 2016 Share Posted November 21, 2016 (edited) Only 6ers and Jr's had the 4050 hex buffer. It actually took some of the load off the TIA as many of the functions were passed through it. 4sw systems had the buffer eliminated and suffer higher TIA failure rates as a possible result.

AtariLeaf Posted November 21, 2016 Author Share Posted November 21, 2016 I'm going to try and swap a riot out of a good system with one of the jailbar systems and see if that makes a difference before i order anything. I'm not totally convinced its the riot that is causing the jailbars. The shadows on the numbers could be RF too couldn't it? ALL my RF systems have some blur or shadows like is seen on the scores.

rednakes1 Posted November 21, 2016 Share Posted November 21, 2016 Might not be the RIOT, I agree. I see shadows on numbers on my composite modded 4-switch as well. Best example - the number 1 in the first screen of Adventure. Quote Link to comment Share on other sites More sharing options...

True. In my case, it was like pieces of the numbers were missing. I do not see that on any of these pics. 1 Quote Link to comment Share on other sites More sharing options...
AtariLeaf Posted November 21, 2016 Author Share Posted November 21, 2016 I'm kinda hoping it is the Riot though. If it isn't, I'm still in the same boat - mysteriously owning several systems with an annoying symptom no one can seem to identify for sure or what causes it or how to fix it. Or, and this one is important to me - why I have several systems with this problem when almost no one else has it or has even heard of or seen the phenomenom. Atari 2600's aren't supposed to have jailbars 1 Quote Link to comment Share on other sites More sharing options...
