marty_rules2001 Posted November 25, 2002 Share Posted November 25, 2002 Help! I have an Atari 2600, 5200 & 7800. The 5200 is a two-port system. I was under the impression that this system can be hooked up to the TV via the connector box used for the 2600 & 7800. However, when I did it, I started to play Pacman and about half way through the first board the screen went fuzzy and then to complete snow. I thought I toasted my switchbox but after I hooked the 7800 back up, that system worked fine. To ensure I didn't toast the 5200, I hooked it up again and only turned the system on to make sure it was still sending a signal. It was as the startup screen for the game displayed. I turned it off and wondered if I need to get my hands on the four-port connector box. Any suggestions? Marty Quote Link to comment Share on other sites More sharing options...
NoahsMyBro Posted November 25, 2002 Share Posted November 25, 2002 Well, I can't say what the problem IS, but I can tell you that the 2 port 5200 will work just fine with the switchbox used for the 2600 & 7800, and that is not your problem.

+Cafeman Posted November 25, 2002 Share Posted November 25, 2002 I use the exact same Radio Shack RF unit for 2600, 7800, and Intellivision -- works fine. If you have an old RF, maybe splurge and buy a new one at Radio Shack? they are under $10 I'm pretty sure. Quote Link to comment Share on other sites More sharing options...
marty_rules2001 Posted November 25, 2002 Author Share Posted November 25, 2002 Cafeman, I did just that over the weekend! It's brand new and I don't want to run the risk of burning it up (if that can even be done) and then not be able to use any of the three systems. The only thing I can think of is I have two power supplies - one from a 4-port system and one from the 2-port system. I don't know if that could have an affect or not, but I thought I'd mention it.

+Cafeman Posted November 25, 2002 Share Posted November 25, 2002 You should use the 2-port power supply with the 2-port system, then run the 2-port's wired-in TV cable into the GAME part of the RF. Are you sure the 5200 is set for the correct channel? I've never heard of an RF getting burned up. Not sure that's possible. The 4-port 5200 has its on RF, in which the power plugs directly into this unique RF itself. You shouldn't be using any of this for a 2-port system.

+Mitch Posted November 25, 2002 Share Posted November 25, 2002 The RF switchbox for the 2 port is identical to the 2600 and 7800 switchbox, as the other guys have said. The 5200 power supplies are interchangable, it doesn't matter if it came with a 2 port or 4 port. I think the most likely cause of the problem is a failing chip in the 2 port 5200. It's hard to say for sure without seeing the unit. Good luck. Mitch http://atari7800.atari.org Quote Link to comment Share on other sites More sharing options...
+Allan Posted November 25, 2002 Share Posted November 25, 2002 Isn't the two-port and the four-port power supply the same part? I didn't think there was any difference. Allan Quote Link to comment Share on other sites More sharing options...
voiddweller Posted November 25, 2002 Share Posted November 25, 2002 Hi, I'm pretty sure they are interchangeable. - VD Quote Link to comment Share on other sites More sharing options...
marty_rules2001 Posted November 25, 2002 Author Share Posted November 25, 2002 Cafeman, Back up a little! 1. How do I determine the difference between the 4-port and 2-port power supplies? 2. How do I determine if the 5200 is set for the correct channel? Is that the circle-and-box switch on the back? If so, which setting should I use? Could this contribute to it coming up, working for a few and then quickly fading to snow??? Marty Quote Link to comment Share on other sites More sharing options...
+Cafeman Posted November 25, 2002 Share Posted November 25, 2002 Okay, first ignore what I said about the power supply, I've been corrected by everyone -- they are the same (news to me!). I am not looking at the 5200 right now, but isn't there a little switch where you select either channel 2 or 3 (or is it 3 or 4? one of those)? If you are using Channel 3 on the TV, you have to set it to channel 3 on the 5200, right? It's been a long time since I messed with these things. It sounds like something is wrong with either your 5200 cable(s) or the system itself though. Does jiggling the 5200's cable (the one that goes into the RF) seem to improve or even affect the picture? Quote Link to comment Share on other sites More sharing options...
marty_rules2001 Posted November 25, 2002 Author Share Posted November 25, 2002 Cafeman, That's just it - I connected it and turned it on and it came up fine. Then while playing (after only 5 minutes??) the screen started to fade to static and then went to complete static - all in about 5 seconds so it's not like the signal just up and died like it was disconnected. I also re-connected it after testing the 2600 & 7800 systems and it came back up but I didn't want to press my luck and possibly do damage to it or the rf box.

sku_u Posted November 25, 2002 Share Posted November 25, 2002 I had a similar problem with my old atari 2600. On my system at least, it turned out that the RF CONNECTOR itself was causing the problem. I spliced on a new one and the system worked fine again. Have you checked the wire that goes from your system to the switchbox for any cuts? That can also affect the image you see on the television.

marty_rules2001 Posted November 25, 2002 Author Share Posted November 25, 2002 No, no problems with the cables or the rf box. The box, in fact, is brand new - just bought one from Radio Shack (which, by the way, the manager said they will no longer be carrying so if you need one, get it NOW).

sku_u Posted November 25, 2002 Share Posted November 25, 2002 Not the box, the male connector that actually plugs into the box. I have a few of those Radioshack boxes. They do not always work that well. I have one of the coxial plugs featured here: http://www.atariage.com/store/Hardware.html I get a much better image on the television through this. Although I couldn't get the plug to work with my 2600 for some reason. Quote Link to comment Share on other sites More sharing options...
marty_rules2001 Posted November 25, 2002 Author Share Posted November 25, 2002 The cables are in good shape as well. That rf adapter - can I get it at Radio Shack (on my way home ) or do I need to order it from the webpage?? Quote Link to comment Share on other sites More sharing options...
sku_u Posted November 25, 2002 Share Posted November 25, 2002 I was just at Radio Shack a few minutes ago. I was looking for an extra F-Coax adaptor. They didn't have it at the one I went to at least. Quote Link to comment Share on other sites More sharing options...
Dantaipan Posted November 29, 2002 Share Posted November 29, 2002 I highly recommend the Coaxial (F-Type) to Female RCA Adapter. I bought a 3-input coax switch and three of the adapters and now I never have to deal with tv/game switches. IMO your problem sounds like a power supply issue.
