Are you working through the 1st or 2nd edition of the book ? I think these are the ones that used ACK.

I remember after I read the 1st edition, bought MINIX ($150 !!), and then was very annoyed to find that the compiler source was not included. Luckily it was '89 or '90 and GCC sources were available.

I’m working through the third edition which I believe is also ACK based as far as I can tell. MINIX version 3.1.0?

The book version is a subset of Minix version 3.1.0 (see https://github.com/rochus-keller/Minix3/tree/3.1.0).

The sursprise comes when you try to compile the minimal book version and find out that it is not as lean as presented in the book but actually depends on hundereds of assembler files (see https://github.com/rochus-keller/Minix3/tree/Minix3_Book_TCC).
