Re: Making new connection for scandoubler?

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!)
