Hitachi HITAC M-200

Hi, does someone have any information regarding this CPU, more specific how to delid them. there are 2 types of dies on it, depending the model. but all of the ones i solder out it still has like a "base"

any techincal information would be helpfull. Tnx.

sure let me show you my first attempt.

here is the next one i will try to. impressive those caps are actually a bit more complex.

I have a similar issue with a SPARC64 X the face of the die has like a layer of PCB attached to it.

I will try to make more pictures with my "microscope"
