I had never heard of Lucas Deeco until working on these terminals. These two terminals are fascinating IP65 touch screen terminals for use in hostile environments. (Hostile to computers) Let's dig into what makes these tick and see if I can figure out why one of them is not working.

![Lava RSC: A great NES clone with RGB output
Note: See updates in pinned comment.
The NES was my first game console and I still regularly play on it to this day. Up until this point, I have avoided any of the Famiclones that have come and gone because I always understood them bad or just brought nothing new to the platform. So I was shocked when I found this one which shows so much promise as it offers S-Video and RGB output with 100% compatibility. So in the video I go in-depth on this console and even do a little mod on it.
What does the SD card do?
Does it have any lag?
How is the video quality?

@itsnathandivino Repair of a very broken Mac SE/30 motherboard](https://i.ytimg.com/vi/X-nh0HydJWA/mqdefault.jpg)
![I tried to fix a cursed Nintendo Famicom. It broke me.
This Famicom is in rough shape, lets try to fix it and A/V mod it!
Part 1: This part
Part 2: https://youtu.be/YDyRrV0RXnE
Freebie Famicom Composite Mod:
- Change R6 to 220 ohm (along edge of board)
- Change R12 to 100 ohm (along edge of board - this changes voltage divider to output a stronger video signal)
- On RF modulator, remove components to isolate CVBS, there are 2 or 3 components you need to remove, or you can cut traces.
- Install 100uf / 16v cap with positive side facing signal source (Famicom motherboard, this blocks the DC)
- Connect negative side of cap to RCA jack going to your monitor
- Try 102 tantalum cap (1nf) between video and ground at RCA jack to smooth video
- If you want to reuse the RF jack for video, you need to isolate it by removing a couple components. Then add a wire to connect it to the 100uf cap above.
Note: video will have jailbars, this is just how the video is on the earliest Famicom boards.
For Audio, you can take the audio right off the feed going to the RF modulator, but you should install something like a 10uf cap, with positive facing the Famicom motherboard to remove DC offset. You should remove components on the RF modulator to isolate the audio going into the RF modulator.
Note: Audio will be buzzy, with interference picked up from the Famicom main board.
