This code initialize Smalltalk, but I haven't found where Smalltalk is stored. Smalltalk is not a SmalltalkImage inst var nor class var neither Smalltalk class inst var ... So I wonder where to find it ...

Smalltalk is a global. Globals are stored in a SystemDictionary. So far the only instance of SystemDictionary is the value of [Smalltalk globals]. Currently Smalltalk is a SmalltalkImage. SmalltalkImage has an instance variable called globals which holds the SystemDictionary. So

(Smalltalk globals at: #Smalltalk) == Smalltalk.

But SmalltalkImage also understands some of the protocol of SystemDictionary, because originally Smalltalk was a SystemDictionary, so you can write this too:

(Smalltalk at: #Smalltalk) == Smalltalk
