I mentioned this in my thread about the little RGB add on I put together for my Jag and thought perhaps a separate thread would be appropriate. I an thinking of building a run of Jaguar A/V cables with RGB as well. The cable will have 6 to 12 inch pigtail/harness that has female Stereo audio jacks, female composite jack and female s-video jack as well as a plug for RGB monitors. This way you can plug in your own cables to the harness with whatever length and quality of cable you like. Need 6 ft audio but only 3 ft of s-video? No problem. Use your own cables that suit your needs. Before I order and test some designs, I need help deciding on a few things: 1. What RGB connector should I use? I want to use a round 13 pin DIN like Atari RGB monitors do. That way you just plug in the cable from the Atari SC1224 monitor and you are ready to rock with RGB video quality. This is what Atari probably would have done if they had an RGB cable for the Jag (besides Scart). However I could use a more common 9 pin DB connector even a 15 pin HD-15 (vga style connector). Thoughts? 2. Serious Interest in these? I want to build at least 10, but probably no more than 25 for an initial run. Another run could be done at a later time if interest warrants it. Let me know your thoughts on this. I want to order parts over the weekend for a couple test cables to see how they work out. If all goes well, I can probably still building these for the initial run mid-ish November.

If you were to plug in a true PAL machine into either the composite or Luma/Chroma inputs of your 1084, you would most likely just get black and white. PAL Antic in an NTSC machine isn't 100% PAL. RGB on the other hand doesn't matter. 50 or 60Hz like most RGB monitors will work just fine.

Looks good. Would this be easily adaptable to the 130XE? Mine has some vertical lines in the picture. Oddly enough mostly on the left side.

Thats not analog 15 KHz RGB. Its regular 31KHz VGA. With this harness the best you could do is S-video. Unless you purchase a costly RGB to VGA upscaler. This is one reason I am reluctant to use a HD15 pin connector on the harness as some could mistaken it for VGA output.

You have an RGB input on your TV? Or is it labeled RGB and actually a VGA input? Some HDTV's label it that way.

Yeah, HD15 pin (vga connector) to 4 or 5 BNC is pretty common and cheap. I bought mine from eBay for like $6

Hmm. Any serious interest from other users as well? I was thinking of build a run of RGB adapters however I haven't decided on all the details. Here is a couple ideas/options I had in mind: 1. Cable that has regular 6ft S-video/Composite and Stereo leads along with an RGB connector as well. 2. Pigtail Harness style version of the above. Cable has ~12 inch female S-video, Composite and Stereo and RGB connectors. That way you can plug in whatever length and quality of cable you like. Uses regular cables. 3. Something close to what I built in this thread. These require quite a bit of work as far as connector cutouts go and I am not sure this is the what I want to do. Personally I like option 2. That way if you only need a 3 ft cable or 12 ft cable, you are good to go with standard A/V cables. The RGB connector is a sticking point though. Since this is for an Atari product, the proper thing to do would be use a female 13 pin din connector that way you can plug in a regular Atari SC1224 monitor and go. No special cables or adapters required. Just plug the Atari monitor cable into my Jag harness and go. I could go with DB9 or HD15 pin connectors, however 13 pin Atari seems most appropriate. I could sell loose male 13 pin connectors as well for those need to build an RGB cable for their monitor (like Commodore 1084 and etc). Perhaps a second thread outlining this would be a good idea. Thoughts?

I don't have the cd unit so I am not sure. Though looking at some pics of cd unit via google, I would say it probably does get in the way. Hmmmm... Might need to work on version 2 of this.

Looks ace!

Yeah, its the one in my sig. Its not really a TV per say. Its a broadcast monitor much like Sony PVM monitors. Has 2 composite inputs, s-video and RGB. No built in TV tuner so its a monitor. Both NTSC and PAL compatible. Picked it up off ebay earlier this year for around $80 or so shipped. Works great with pretty much everything I have thrown at it. I have also used it with Amiga, Genesis and Atari ST via RGB. Currently its shared between the Jag and my 8 bit Atari stuff.

Recently picked up another Jag and wanted an RGB cable for it, so I knocked together this cheap-o RGB adapter box so that I can plug in my RGB cable to my monitor. Plugs directly into the back of the Jag. Stereo audio connectors and a HD15 pin port for my cable. My RGB cable has the 15 pin connector to 4 BNC connectors for my JVC monitor. Similar setup to Sony PVM monitors that have RGB input. Side view. Since I didn't have the proper 24 pin connector handy, I cut down a 34 pin 5.25" floppy disk drive cable to be the proper size. I left the ribbon cable attached and cut it down to the wires I needed. Then I hot glued it to the front of the case and drilled small hole and ran the wires into the case. Inside view. Not much to it in all reality. Direct connections for Red, Green, Blue, Gnd and Composite Sync. Same thing with Left and Right Audio and Gnd.

That might be going a bit far. While Crownland is very impressive, I dunno if I would say it exceeds the better stuff on the NES or SMS.

Are you saying the new preorders will be sent by Nov. 10th? Or that prior orders from the last batch will be sent by then?

Perhaps the new board should have a built in game too, kinda like on the XEGS. Maybe Prince of Persia.

Same here. Also interested in one.

I am not sure how practical it would be, however I like the idea. Also, instead of just doing a 1 to 1 motherboard design, perhaps integrate into it some of the most popular mods that are being installed. Dual Pokeys on the board with a switch to toggle between stereo/mono. Integrated 512k sram. Perhaps SIO2PC interface. Higher quality composite and s-video output...dump RF jack if possible. A feature us NTSC folks would like would be the ability to have dual Antics and dual crystals. Then with a simple switch we could go between NTSC and PAL modes. All these could be optional and not required for system usage.

Thanks for the magazine. However, and I know this has been brought up before, why do you guys keep putting scantly clad women on the cover?

Need some pictures of course when you are finished.

Safest route: Unplug the machine from the wall. Take the machine apart, take the top case off and take the top metal RF shielding off. Carefully press down on all the socketed chips to reseat them. Good chance a chip has come partially up out of its socket. Least Safe: Atari 4 inch drop. Pick the machine up (no need to take it apart) and drop it from about 4 inches above your desk back onto your desk. This will also reseat the chips. However this old machines are fragile so I wouldn't do this all that often. Best bet is to take it apart and manually reseat the chips.

30 pin simms are pretty cheap. You can probably pick up a whole set on eBay for next to nothing. That way you can prove/disprove if the existing ram is the issue. For example: eBay Auction -- Item Number: 330590859845 $10 shipped for 10 x 1MB simms. Plenty of leftover simms in case you want to have spares or upgrade another machine down the road. This is a REALLY good price for them. Its the route I would go.

There is some confusion in terms with these products. SIO2USB is a standalone device that allows you to plug in a USB thumbdrive (or similar) and boot up programs and such from it. Functions like a SIO2SD or SDrive and emulates a disk drive. http://home.arcor.de...l/sio2usb_e.htm http://www.youtube.com/watch?v=bFUzTAum_iI SIO2PC USB addition plugs into the USB port on your PC and allows you to use the APE software to transfer disk images and such to your Atari. USB version of the regular SIO2PC RS232 serial model. http://www.atarimax..../documentation/

Yep. No modulator = RGB only. There are a couple different RGB to s-video/component or VGA converters on the market, however none specific for the atari. You will need to do some experimenting to get them to work. I would register over @ atari-forum.com to see what others have done.

Sounds like taking the NTSC 1200XL and doing a true conversion to PAL instead of just replacing the Antic (which is like quasi PAL)? I would be up for one as well.

Still have the NTSC C64 and 1541 drive left. Willing to make someone a great deal on them. How does $75 shipped sound for them?
