Is there a thread that discusses the FN's capabilities and operation.

Will these units be available for purchase?

I recently purchased an 800XL for parts or repair. It will not boot to basic. It will boot with a PAC MAN cart and a POLE POSITION cart. It will not boot with a STAR RAIDERS nor a BASIC cart. With no cart it boots to a blue screen with a white square but no READY prompt. The RAM and the 40 pin chips are the only ones with sockets. Does anyone have a hint where I should start desoldering chips and installing sockets?

I am very late getting to this topic but I would definitely plan to purchase one of these. The ability to utilize the cartridges is a big plus.

Will the driving controller work with the 800XL?

Atari 600XL and an 800XL.

Nevermind, I found out that there were two pegs in the center of the long sides that were held together by friction only. Gentle pressure with a flat blade screwdriver got the pieces to seperate.

Does anyone know how to disassemble an Atari tracball? I have removed the screws from the four corners but something is silll holding upper and lower cases together. I need to give it a thorough cleaning.

The 512K memory upgrade, operating in the 256K mode will allow an 800XL equipped with Omniview80 to run the 80 column version of Atari Writer Plus. I also have a 1200XL that has been modified with the 800XL OS and Omniview 80 that will run AW+80. After posting this I found where Nezgar had posted similar information.

Thank you for that file. When I configure the RAM to 256K the 800XL acts just like a 130XE. I can run a Newell modified version of Atari Writer Plus that was written for 80 Columns using OmniView80 and the very old SpeedScript character font. The Rambo and Wiztronics upgrades don't use separate Antic access and the program will not run with them. The Newell 256KXL memory upgrade will run the program but they are very rare. I have only had two since I have been tinkering with Ataris. I still have one and I sold one. (BAD MOVE). If I can get this memory upgrade to work on the 1200XL I will have IMO the perfect Atari machine.

What response is the target query looking for?

Thanks for this, I believe it is just what I need. Can I copy a file from an XDOS disk to a DOS 2.5 disk..

OK, by numerous attempts using trial and error, I figured out why I couldn't get to BASIC. I was operating in my OMNIVIEW 80 OS and there was no BASIC. I still don't know how to use the XDOS commands. I would like to be able to copy files at least.

I have installed the 512K RAM upgrade in an 800XL. I would like some help in using the commands to change the configuration from 512K to 256K. I have downloaded the file containing the files and I have loaded the ATR onto a S-Drive. I have even loaded the file on the 800XL. That is where my success stops. I do not know how to get out of the XDOS environment back to BASIC or to anywhere else. I am not familiar with XDOS. I have downloaded all of the information I could find with the DOS commands. The only thing I have been able to do with the DOS is load the menu.

I would like to buy a 65XE case or a non-working 65XE for parts.

I would like to get a Newell 256KXL memory upgrade for a 800XL. I would also be willing to trade an 800XL with a 512K memory upgrade and supervideo 2.1 upgrade for an 800XL with the Newell upgrade.

I checked my setup with MYDOS 4.2 and it showed 1522. I checked my 128K 130XE and got the same number. I am not sure if everything is working as it should. I had to follow the 800XL instructions.

This is slightly off topic but I have the 512K memory upgrade installed in a 1200XL that has been modified to use the 800XL OS. When I set up a RAM Disk, how many sectors should the RAM Disk have?

I bought another 1200XL on eBay for $150. Computer has good picture with composite video. Keyboard doesn't work. I suspect that a good cleaning will have everything working. I will connect the chroma, add 5V to the SIO, and probably do a Super Video 2.1 upgrade, and the 800XL conversion.

If he would put this on the open market he would make some sales.

Are there any instructions anywhere for a video upgrade such as SV 2.1? Do the video components match up with the 130XE?

If you want to repair the existing video output you should check out the SuperVideo 2.1 modification.
