The UAV Rev. D Video Upgrade Thread

Recommended Posts

Amazed by the info here - thanks to all. 

 

I have the UAV (rev D) and will install it in an 800.

 

Has anyone articulated the process for the A8/800.  I THINK (hope) and can do it based on the threads and the instructions, but I'm not certain.

 

Thanks for any help in advance.

The option for the 800 is the Super Color CPU Card by tf_hh here in these forums.

Here's my attempt at installing the UAV, rev D on the A8 MB.  Not working - no signal.

 

Can I use the composite out via the 5-pin DIN connect or do I have to use the RF modulated output?

 

I did 'lift' (disconnect) the components specified in the instructions.

That is why there is the Retrotink2x.

 

My point was that LCDs will always show the artifacting that was always present on composite and that the CRT was so good at hiding and blending away.

 

Forgot to mention another thing. Your image is stretched to 16:9 and under proper 4:3 aspect, the ghosting/bleeding...etc is much less noticed.

 

I got a Retrotink2x and it still does the ghosting/bleeding. Grrrrr

You should take some close up pics of what you are seeing so that we can see and better understand. And are you using composite or S-video output from the UAV?

I will when I get a chance. I've clipped the 5 pins of the RF box and that helped out a pretty good deal. I'm leaning on using the S-Video to the Retrotink2x. Maybe I'm expecting too much but the composite looks really bad still.

Remind me what you have the UAV installed in again? If talking about the 2600, I've never installed the UAV into a 2600 yet but I know that the composite from the UAV on a 7800 provides really good composite  from a 7800 and I've installed the UAV in just a "few" 7800s over the last nearly 3 years now. 5200 produces a good picture, but with noticeable thick jail bars on the left half of the screen that appeared to be caused by the DRAM in the system being noisy.

6 switch 2600... I've got another UAV in an 800... and two Super Color CPU Card's in both a 400 and another 800.
The Revision C and D UAV that I've put in two 2600's both look like the image I supplied earlier using Adventure as an example.

I would like to say thanks to MacRorie for the fast shipping of the UAV and other hardware pieces. 

 

The UAV (the kit version) is already installed in my original 65XE with shield: 

 

1.- I did not want to go to the process of desoldering the CD4050 (I really suffered last time I desoldered a chip from this same motherboard), so I first soldered 5 pin headers (one by one for Lum0-3 and Synch) to the feet of the cd4050 (if my memory helps me.. pin 3, 5, 7, and 11 and 14 maybe?). So I soldered just the required minimum for the 5 signals. I used the supplied pin headers (the ones originally supplied for the configuration jumpers) but I cut (separated) them.

2.- I build jumpers with little pieces of wire (from a resistor) and soldered to the UAV to "configure" the UAV to XL/XE mode and redirect the signals coming from the cd4050. I did that to keep the uav low profile.

3.- I connected (soldered) good thick (but not that thick) cables to 5VDC and GND pads of the UAV and found a good place (thick trace) to pick the 5VDC from the motherboard.

4.- I soldered 4 cables (or wires) directly to "output section" of the UAV: Chroma, LUM, composite and Chroma In (input). So I did not use the green connector supplied (to keep the profile low)

5.- Since I wanted to avoid any interference and I want to eliminate the vertical lines on the left size of the screen, I cut all (except the audio and ground) traces arriving to the monitor socket Din 5 pins.

6.- I soldered all the outputs wires (Chroma, Luma and Composite) to the corresponding pin directly to the DIN socket (UAV-->DIN5 Socket) I also connected ground directly to the ground pin of the Monitor DIN5 Socket.

7.- I solder the chroma input wire to the right point in the motherboard (GTIA pin 21 or a close resistor.. I don't remember)

8.- Finally,  I soldered the UAV to the 5 pins I installed in the step 1 (very carefully to be sure the pins were entering the right position), so the UAV sits on top of the cd4050 separated by small space, but it is still low enough to install the shield back.

 

The vertical lines are gone, and the quality of the image is much better. I don't know why people keeps saying that the 130/65xe video circuit was good enough. Maybe I got bad luck with this unit since this 65XE (with 130XE motherboard) always produced vertical lines and super saturated colors (I have to decrease the saturation of the TV to get something close to the 800XL and 600XL I have).

 

Thanks again!

Glad it all worked out!  If you are coming to PRGE, I will be there in Booth #166!  Enjoy your "high definition" 65XE!
