Kernal and differences

Hi!

I'm comparing differences between Commodore 8-bit computer Kernals.

We all know about C128, C64, VIC20, C16+4, C65 Kernal is also very good documented.

But I'm lost in these platforms:

PET - where to get really first PET-2001? And how different are later models?

CBM-II Series - this is really variable, but really where to get Kernal routines working on each model? The same PET Series...

Commodore LCD - very rare computer, nearly undocumented - I can try to ask emulator creator... so resource I can find and later post it here.

Also - only VICE it makes different, but how are different CBM-II models between C5x0 ? Why they created different emulator - really all about CBM-II Series what I know is very little info.

So, can anybody post Kernals of these machines?

Thank you all for patience.
