[Coco] Disto 2 Meg kit

Does anyone here have technical knowledge of the Disto 2 Meg kit?

I want to put one into an Australian Coco3, but there's some differences in 
the components with respect to the 2 Meg kit.

1. The wire that should go to C60 connects to the junction between a 
resistor and the 28.63636 MHz crystal. The resistor connects to pin 2 of the 
GIME chip. In the Australian Coco3, that capacitor connects directly to pin 
2 of the GIME, and the crystal is 28.475 MHz. The crystel is actually one of 
those oven type devices in a larger metal case.

2. The other wire connects to HSYNC (pin 40 of IC5), which is the same as 
the Australian Coco3, but the HSYNC pulse is at a different rate to the US 
version.

Does anyone have any experience with this? Will it work, or should I just 
forget it?
I'm inclined to just try it and see if it works, but before I do, I'd like 
some input to this.
