I found a 3300pf, 2kv capacitor at a component shop near my house. I soldered it on and it looks great. Only 1/4" black border now. Here's a screen shot, and I'll upload a picture of the CC once I find a USB cable. As you can see, it's back down to 256 colors. I'm going to buy a 256KB VRAM which should be enough for thousands at 640x480.
