Just use a multimeter of some sort to figure out which wire is which pin.

Well I for one have never even seen/heard of anything about the 07's until I came to this website haha.

You can build an entire arduinoboy into a DMG-07 btw, looks super classy.

This should help you out a bit : http://chipmusic.org/forums/topic/6698/ … lp-please/

Also, these link cables are cheaper and you get two adapters/keyboard cables out of one.

None of that is to disqualify your input, which is certainly valid. What was the debate? I'm not sure why the re-pinning method wouldn't work… it's not like the fifth (ground) contact in the DMG-07 cable actually goes to anything inside the keyboard when you use one of those instead.

As for the jeweler's screwdriver thing, the smallest ones I have a 1.2mm diameter flatheads, and they were still too big to depress this style of pin on each side. hmm

From what I've read there has been much debate on the DMG 04 cables for attachment in keyboard modifying.
All I am saying is that it'd save you a lot of time and frustration to acquire a mystical DMG 07 (I have yet to try this ever though, just two DMG 04 wires at least one with the pin swap method)

From what I can tell, the two slots on the top of the cable body are accesses for a pair of microtweezers to spring the barbs that keep it captive in the plug body. So, instead of pressing them out with a jewelers screwdriver, one would ideally use a pair of tweezers smaller than I have to squeeze the two sides of the pin – I ended up using bent staples. Really.

When I got it out, I took another picture to illustrate what I mean:

By the time I finally got this one out of there, I'd bent the pin in such a way that it wouldn't spring back and stay in the new slot. I had to carefully bend the barbs that hold it in place back out a wee bit, and then it stayed in its new slot.

So, there you have it: One weird hardware variation on the DMG-04 Link Cable. Modders Beware!

I chose to use DMG-04 cables and to swap the pins using Trash80's method.

However, when I got my cable apart, I found something anomalous:

As you can see, these don't match the plug body and pin design from the DMG-04 used in Trash80's demonstration.

Anyway, I've managed to complete one of these, but I'm having a lot of trouble getting the pin to release on the second (the other end of the same cable). I had to cut part of the plastic bridge over the pin slots away to even be able to depress the pins.

This raises some questions:

  • Has anyone else encountered this DMG-04 hardware variation before?

  • If so, what were your experiences?

  • How the fuck do I get this pin out?!
