Decided to try a few different diagrams to maybe get this chip working on pre v9/10 ps2s.
I managed to get it working with a v7.
I used all points on the chip to get it working.
Used cx point from the V9/10 Modbo 4.0 pro diagram. Same solder point on the v7 mobo although the chip is in a different location.
The F point is the same as Magic V on a v7 mobo.
The rest of the points are easy to figure out.

Now to try it with a few older versions.
