Please help me identify this modchip

It looks like a Magic4 or "NH3" clone..
but some points are missing.. like "Y".

Which mod is it? where can i find the installation diagrams?

thanks in advance.

believe it is a HK Messiah2

Its a clone, sometimes called the messiah-tw also called the magic 4. It doesnt have a "Y" point because it has its own onboard oscillator. Here is a diagrom for a v7.

thanks for your great support.
i'll google some info about it.
In fact a v4 diagram is what i needed (already found)

thanks again.
