nice work!

5 years later

having some dead pocket screen and dmg screen motherboard, i was searching for a way to transplant a mgb into a dmg mobo (just for fun) and some folks already did this !

even if some people tried to explain how to do it, the best way after all was this sketch :
https://chipmusic.org/forums/post/205616/#p205616

using the correct pinout and eagle to make a pcb, the goal here is to do the same PCB as this one :
https://oshpark.com/shared_projects/vr4ATKD8 
but i wanted to make it fit into the shell.

finally I just use the FPC connector from the gerber file and I redid all the traces using the scan of the handmade draft drawing

here is the result after 1 hour of eagle pcb drawing and 2 weeks of waiting from oshpark :

the only issue is about the connector, the ones i ordered are made to have contact on the bottom side and the connector needed to contact on the top (like the connector on the pocket console). to correct the issue, i just remove the black "gate?" and made it upside down. the contact is not perfect but it work this way.

the dot on the soldered connector is pin 1 (important). 5 wires to solder, i use kynar wire.

What gauge wire did you use? I have 28 gauge but it seems alittle to thick by the time its tinned and soldiered in place. I don't end up with nice gaps between the pins when it's in place. Would soild wire be best?

The engineering solution is brilliant! I'm stealing it.

I just finished mine.
I cut a slot in the LCD PCB above the ribbon cable to slide the ribbon cable through the PCB to make room for the MGB ribbon connector. I scraped off some of the solder mask and soldered the MGB ribbon connector on to the DMG LCD board using the ground tabs of the connector.

I then strategically placed the wire along the board and glued it in place. At this point this board is no more difficult to install than a regular DMG LCD.

The best part is that I can replace this cancerous LCD with a new one just as easily as I could replace the LCD in an MGB.

And a Hand Held Legend panel fits with no problem.

Thanks for the detailed pin out! It really made this modification a breeze.

This is pretty great. I've been wanting to do this for a long time.

I hate to to revive an old thread but...

a user here [can't remember who, sorry dude!] shared this info with me a while back:

Rough Scans

Good Images

I've been meaning to try this for a very long time.  That damn DMG LCD ribbon cable has pissed me off so much.  I tore one long ago while backlighting.  Good job on this.  If you do or learn more with it, please feel free to share.  Others have done it before, but I don't think much info was posted on it.

I should find the pinout image I made...

Thanks I too thought there should be a tutorial or at least a nice photograph. But sadly no. Or I wasn't lucky enough to find one.

Anyways glad you find it helpful guys, feel free to drop me a line have you got any troubles reproducing it.

I really thought this info was already out there.... Since like 2 other people got it since I was flamed for not publishing. Nice work!

I'm getting a gameboner here..

I know what my next project is going to be!

Fantastic!  The veil of secrecy is lifted.

I can certainly do more pictures, but what exactly you'd like to see?
this one should be enough to reproduce the mod
Just check with the pinout I provided in the first post. You can also check with the pocket PCB because it has numbers 1 and 18 near the corresponding connector pins, this is how I knew where to solder the wires.
If there's a big interest in this mod I can probably make a tutorial, but not today I'm too freakin tired of messing with the wires
