​I just finished installing the the Rambo 256 upgrade to my 1200XL. I am posting pictures so anyone that does this in the future can possible use the visual aid. I had to modify the shield in two places for the Rambo. The shield was touching the Rambo card and rather that solder the ribbon cable to the pins on the PIA chip, I cut 5 connectors off of a chip socket and soldered the ribbon cable to the socket. Now if I decide for some reason to uninstall the Rambo, I won't have to desolder the ribbon cable from the PIA.

I just finished applying the supervideo 2.1 to my 1200XL and the color and clarity is fantastic. I can read the 80 column print from The Last Word with no trouble at all. I was not able to do that with my upgraded 800XL, the upgraded 130XE, or the 800XL with the UAV-D. I also removed the RF modulator box. I don't know if that had any effect or not but I am going to remove the RF next time I do a mod on an 800XL.

I know about the chroma-luma and I know about the cables, I had one with the s-video connection and it didn't work, I don't think it was wired correctly. The probably used the composite video for the chroma and I have composite disabled. I want to have a dedicated s-video jack that I know will work as intended.

Has anyone attached a S-video connector to an 800XL. I am considering doing that after I finish my next Super Video 2.1 upgrade and I just wondered where would be the best place to attach the wires. Could I connect to the din plug, the din connectors on the foil side of the board or is there a more direct method that would not cause any degradation to the signal.

Is it because there is no 5V on some particular pin of the SIO?

Is there any particular reason why my 1200XL does not recognize my SDrive-ARM. The 1200 has the standard OS and has the RAMbo 256K memory upgrade.

Quadrunner, you may have been correct. I gave the keyboard a small flex and the problem seems to have cleared up. It booted correctly 10 straight times. Another question, I recently saw a post by someone who had written a BASIC program that tested extended memory but with my limited memory I can't remember where I saw it and search hasn't yielded the proper results. ANYONE have a better memory?

I have just finished installing a Rambo 256K upgrade on my 1200XL and there is a problem somewhere. When I turn on the computer with a basic cartridge, I get a loud beep and then a blank blue screen. If I press a key I get the sound of a keypress but nothing appears on the screen. After a minute or so, (I haven't timed it to see if it is the same every time) I get the sound that the computer makes when booting something, and a BOOT ERROR message. Then the ready prompt appears and everything seems to be normal. I have tested all the keys and have run a short basic program while NORMAL. I assume that I must have a jumper wrong or something. Any trouble shooting tips. I will post a picture of my install in the near future.

Is there a set of updated instructions for the supervideo 2.1 upgrade for the 1200XL? I know there is one for the 800XL which instructs the user to replace resistors rather that piggybacking in order to achieve the desired resistance.

How do you, or is it possible to change/convert a ROM file to an ATR file

Sam's manual says to check C2 for 5v, I know where C2 is and I can check it but I can't find any reference to what the nomenclature is for the capacitor in case I need to replace it. Does the 130XE generally have the same part designators as the 800XL; I have a parts list for the 800XL.

Yes it has worked, as a matter of fact while I was checking resistance on the switch it came on, so Now I have to worry about it burning something out if I turn it on to check something.

I have used 3 different power supplies that work perfectly with the other XE.

I have a dead 130XE, There is correct voltage at the DIN connector and on the bottom pin of the switch when the switch is OFF. When I turn the switch ON, I get no voltage on any of the switch pins or anywhere else on the board. I have replaced the switch and tried multiple power supplies. What could be some possible problems, I have a workinf 130XE that I am using for comparison purposes.

Thanks

Does it matter which gets luma and which gets composite.

Does anyone have a good set of pictures for a 1200XL install?

Does anyone hace pictures of a good Rambo/1200XL upgrade. I have one that I have hesitated to install because I can't really follow the instructions that come with the package.

Thanks very much.

How do I "mount" a blank ATR file? Do you mean establish a folder and give it that name."blank.ATR".

Thanks, I stumbled across the solution while I was waiting for a reply. I did not expect DOS to give me a complete menu for the ARM drive.

After I boot with the ARM connected I get the following screens, when I press the inverse key to load LW, I get the sound of a file loading for about 5 seconds and then the computer goes to the ready screen. I have tried pressing inverse while pressing option, without option, and I have tried each of the ATR files. When I try with the 2nd LW file, I get a no DOS present prompt. Maybe I need a better download location. I have tried two locations. I believe the one that gave me the files I am using came from a link on one of the AtariAge forums.

I have downloaded LW 3.21b and it shows up as 3 ATR files. I moved it to my ARM device and I can not get it to run. Is there something that I am missing. Is there an actual disk version out there somewhere?

I have a SIO2SD drive by Lotharek, and an ARM drive. Does anyone know if there is any way to write/save files to these devices from the 8-bit computer? I have an 800, 800XL, 1200XL and 130XE.

OK, the lock/unlock on the adapter is the write protection; that problem is solved. NOW,can anyone tell me how I save files to the ARM from the Atari. I have loaded AtariWriter and SynCalc to the ARM, after I create a document or a spreadsheet is there a way to save them to the ARM?
