That is the "railroad" diagram of the Smalltalk-80 syntax (also
available in one of the August 1981 Byte articles). In the front inner
covers there is an example of the class and method presentation format.

But every chapter in Part Two does start out with a class hierarchy
diagram with the classes presented in that chapter enclosed in a gray
box. I thought about scanning this in, but there were so few classes
back then that it is faster for me to retype it:

P.S.: I copied the blank lines though I don't think they have any
meaning beyond making it easier to draw the gray boxes for each chapter
that I had mentioned
