It doesnt matter because every Iron Mole has a Motherboard inside it, And 1 Motherboard controller can be used for multiple models.
If you need a specific one then TP95S-2.

The Picture Explanation
Red Lines : The things I circle with red lines is the controller box, Inside it there is a motherboard which we are diagnosing now and trying to figure out the issues going on it. We can see the control panel the buttons as well as screen.

Yellow Lines : After the screen is turn on and everything is ok, this is the program used for tunnelling the ground and many more options, which i do not have much knowledge.

Most likely this is CLK signal for ISA or another one.
Check and compare the signals on Clock/Data chip. Start from CLK pin
