UAV and Composite Video

[QubertWI]

I've always been a Commodore guy but I've collected various 8 bit systems over the years.   I retrieved a bunch of stuff I had in storage with the intent of selling most of it off.  I had a couple of Atari 800XLs and 1050s that I needed to clean up and test before selling, and I found AtariAge while searching for information on repairing one of the XL keyboards and one of the 1050s.  In the process, I discovered this whole new world of Atari.  I managed to get everything working and next thing I know I'm installing a U1MB and a Side3 and having a ball.  The amount of community activity and the quality of the new hardware and software for the Atari systems is really incredible - much more than the Commodore scene.

 

Anyway, I've also purchased a UAV so I could connect it to a Commodore 1084S monitor using the luma and chroma signals, but I also want to use it occasionally with a composite (combined signals) LCD monitor I have.  My question is... does installing the UAV disable the composite signal?

It depends how you install it, but it has a composite output in addition to S-video. If you install it piggybacked with its own separate outputs it will leave the original video circuit alone, including composite video.

I believe what you're referring to is the original RF signal, not the composite signal. When you install the UAV, you remove the 4050 chip and replace it with the UAV. This improves the original composite signal and also give you S-Video, but you lose the original RF output. However, if you piggyback the UAV on top of the 4050 chip, rather than replacing it, you will keep the original RF output.

No, it does not. It improves the original composite signal and also gives you an S-Video output.

You actually don't NEED a UAV to get the Atari computer coonected to the Commodore monitor. But a UAV will make the signal better.
