Ok I saw a video of one that was installed and working but I have a huge problem:
1. 3 pins on the board were bent. In attempting to straighten them all 3 snapped off.
2. I managed to solder some legs back on, connected device to the riser board and then checked continuity of every pin and made sure there were no short circuits
3. Connected to A600 and powered on
The Amiga boots and I get a picture out of the VGA connection. All looked well but, after opening a few windows I start to see graphical corruption on the screen e.g. big clumps of random pixels when a new window opens.
To see if the device wasn't happy with one of my other devices I removed my ethernet card and my Furia accelerator and booted from a 2.04 Wokbench floppy. The problem was visible immediately, with the frame around the main workbench screen broekn up with missing pixels and flickering.
The same graphical corruption can be seen through the regula RGB port if the Indivision is connected.
I removed the Indivision and now everything is back to normal.
I'm not sure where to go from here?
