PC-1500 : The Book of the Grail

Who has not wanted to know exactly what happens in the machine?
I remember rumors that spoke of an amazing book in which we could understand everything … on the PC-1600.
Oh yes, I searched long and I abandoned my quest for the Grail.

6 months ago, a friend offered me some books on the PC-1500.
He told me “there is a book with commented ROM listing.”
I thought it was for the PC-1600 but he told me the title: PC-1500 Intern
What?? For the PC-1500?? Great!

Wow, what a thrill opening my package and discovering this book among other treasures …
Here it is:
