Making new connection for scandoubler?

[nasty]

Hey guys

How easy/hard would it be to make a new monitor connection for the DCE scandoubler?
DCE: Scan Magic (Internal)

its the 2nd image not the top one!

My old one snapped and in a fit of rage I chucked the thing across the room and now I cant find it, but I still have the clip on chip! so what ya think?

Edit:

Link to the part I need to make!

The right part on the second image? You could opt for building it like the top image, 2 wires either soldered to Alice or make a clip on like the one pictured. In that case you only need a flatcable/VGA connector; should be easy enough to do.

If you want to remake the Video/VGA thingy you'll find it near impossible; or at least very hard to find 23pin D-Sub connectors... Although you could possibly rip it off an external floppy drive...

I have to explain this would be my first every circuit project, I have a 23 pin connector and I have an old gfx card, I could take the vga connector off. so all that I guess is going to be needed is the small circuit board, so any advice on how I would go about creating this?

also if anyone has the dce scandoubler could someone take an image of the back on the Part Imageso I can see how the tracks run!

I would also be interested in a good image of the back of that pcb.

You don't really need to make a PCB, just solder the wires directly to the connectors.
Two of the pins get two signals from the 23-pin connector (and can be soldered directly to the connector inside the A1200) and the remaining 8 are Reg, Green, Blue, Hsync, Vsync and a couple of grounds for the 15-pin VGA connector.

The circuit board does absolutely nothing else than look good (and make the product user friendly).

EDIT: Pinouts:

Top side, connector to the right (like in this pic http://amiga.resource.cx/photos/scanmagicint.jpg)

Top pin:    Green, VGA pin#2
2nd pin:    Hsync, VGA pin#13
3rd pin:    GND
4th pin:    Vsync, VGA pin#14
Bottom pin: Red,   VGA pin#1

Bottom side, connector to the left

Top pin:    Alice pin#77 (? 7th pin from the top, l/h side, same side as pin 1)
2nd pin:    Blue, VGA pin#3
3rd pin:    Alice pin#79 (? 5th pin from the top, l/h side, same side as pin 1)
4th pin:    GND
Bottom pin: N/C

I have the version with the Alice clip-on adapter thingy myself, so I don't know the corresponding pins on the 23-pin connector)

While searching around for the broken board I came across one of those svga adaptors, could I some how wire this up as the pcb or is this just a stupid idea?

I did build a replica of this 2nd part off the board.
The soldering is very bad off the original pcb.
Just desolder the vga plug and the 23 pins videoplug and place it on a experiment board.
Preferably a bit thich one so it will be solid.
Only problem is the pingrid is not the same off the vga plug/videoplug so you probably should bend the pins a little bit..at least I had to.
For the connections I had to rub away the gum/wax on the original pcb.
It are nothing but "straight" connections so use some nice wires.
Mine scandoubler got a lot more stabile with this "new" pcb and a fan blowing air onto the internal pcb(it really needs cooling!)
