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.

1200XL - Clearpic or SuperVideo 2.1?

I have a UAV installed, I removed it for the picture. I chose not to install the CV disable switch. -

hueyjones70 replied to Guitarman's topic in Atari 8-Bit Computers
In an earlier post I mentioned that I had performed the SuperVideo 2.1 upgrade to a 1200XL and it didn't work out. I did go back over my work and I even reinstalled the parts that were taken out. I did not use the old parts but installed new capacitors, resistors, etc. When I finished, I still had no video so I went back to the SV 2.1 and performed all of the steps again. NO VIDEO/NO BOOT Then I installed the UAV and everything works with the UAV just as it should. I am attaching a picture just in case someone with SV 2,1 experience might take a look to see if there is anything obvious such as wrong part removed and/or replaced. -
1200XL - Clearpic or SuperVideo 2.1?
hueyjones70 replied to Guitarman's topic in Atari 8-Bit Computers
Two weeks ago I attempted the SV 2.1 upgrade on a 1200XL and when I finished, I could not get any video, no luma, no composite, no chroma. I checked all my work for solder bridges, missed components etc and found nothing so I installed a UAV. This week I started on another 1200XL and I went component by component and checked the video after every component. Initially, I lost video when I removed CR20 so I replaced it. I lost video again when I replaced R23 (180 OHM) with a 75 OHM resistor. (The mod calls for a 120 OHM piggyback but the result of that would be 72 OHM) I thought maybe if I finished the mod, the video would come back but it never did. I then removed the 75 OHM and replaced it with a 200 (I don't have any 180s) and I got video back. It is lousy video. I am going to recheck my components to make sure that I didn't use an incorrect resistor somewhere. Is anyone aware of any mistakes that were made in the written instructions. I have successfully done this mod before but it has been several years. -
I bought one several months ago on ebay and it didn't work until I peeled off the mylar and cleaned everything with alcohol. Then it worked perfectly.

Ambery makes good stuff. I bought an Ambery converter to convert S-Video or composite to HDMI. -

The UAV worked out great. I guess prefer the component by component method for the same reasons a person would choose to make a cake from scratch instead of using a mix. Another reason is that I usually buy these computers on eBay, refurbish, modify, repair, and upgrade them for resale. The cost of the components is probably less than $5 and I can resell them for less and still make enough profit to indulge my hobby. -
New Twist on a Very Good 1200XL Upgrade

hueyjones70 replied to Guitarman's topic in Atari 8-Bit Computers
I recently attempted the SV 2.1 on a 1200XL and somehow managed to botch it up. I couldn't get a video signal at all so I inserted a UAV to sweep my errors under the rug. I have another that I plan to try once more to perform the mod correctly. When I do that I will remove the RF and use that hole for the Composite cut-off switch and use the channel switch to allow for a two OS (XL and Omniview) configuration. -

I found that I was using two different sets of instructions. When I adjusted everything to fit the instructions in this thread everything worked as it was intended. Everything is now good. -

I did copy a set of instructions that had 9, 11, and 12. I also saw a version that said to cut a trace on the MB. -

I can't tell you how many times I read 11, 12, and 13 and didn't see that I had 9, 11, and 12. Thanks.
