Ahh...got ya. When you open a NES, the sockets already have a small cable terminated by the PH connector. Like this:
Most would probably not bother with the PH connector and just solder the wires directly. I find them cool looking though, plus I found it practical at one time to remove the sockets in order to place more parts on the board.

Re: Official parts list
I decided to build a wire-wrap Uzebox in a permanent case, and ordered this part from the parts list. It doesn't fit. Doh!1 CHA10G-ND CONN HDR 10PIN RT ANG WIRE WRAP (for ISP)
The ISP cable has a 6-pin connector, and this is a 10-pin wire-wrap header. I noticed that when I ordered, but assumed I could just connect the cable to the middle 6 pins. No such luck: the body of the 6 pin connector collides with the other pins on the header.
How did you resolve this in your wire-wrap prototype? I can see in the photos that you're using this exact same header, but it's facing away from the camera, so I can't tell if you've modified it. Did you cut off the other 4 pins from the header?
Re: Official parts list
Yes I recall this. Back when I started the project, there was no 6 pins wirewrap header at Digikey (though I think I saw some recently). Anyhow, I used a 10 pin (2x5) header for the ISP header. Naturally, only the middle 6 pins are used. The AVRISPMKII can be opened and you can easily pop out the 6 pins cable and replace it by a 10 pins version. But cutting pins could just be easier (didn't thought of that one).

Re: Official parts list
Ah, sneaky! I just cut the extra pins off, as well as some kind of plastic tab that was in the way, and now it seems OK.
Re: Official parts list
Bumping this thread to mentionned I've completed the part list for revision D1. SD card parts, power connector & optional parts for the SVideo, MIDI and luma trap are now defined. See the first post for details.

Re: Official parts list
Are there any good substitutes for that video encoder? That thing with the socket adapter is costly.
Re: Official parts list
If there would have been one I'd have used it trust me! If you are from Europe and have a SCART interface you can remove it all together. Otherwise don't know of any other DIP chip that can do color modulation. You could perhaps look at the XGS AVR and see how they do it since they don't use the AD725.Are there any good substitutes for that video encoder? That thing with the socket adapter is costly.

Re: Official parts list
I went ahead and put down the cash for one, but I will keep my eye open for something else.
As a side note my TV set has component and HDMI input I may not have needed the chip anyway. But knowing nothing about either of the two hookups so I can't say. I guess I may have to do some research.

Re: Official parts list
Component is similar in concept to the S-VIDEO output (which still requires convertion from RGB) and HDMI is digital and uses a clock faster than the Uzebox itself!

XGS AVR video signal is generated in software but there's color helper hardware to generate the colorburst part of the video signal.uze6666 wrote:If there would have been one I'd have used it trust me!
