yup. This would be an early pdp11 UNIX from the period before the
rewrite in C.

It appears to be a listing of an assembly language version of an
early UNIX kernel for the pdp11 in the pages labelled E*-*; the pages
F*-* are a commentary; G*-* is a glossary of terms used; H*-*
contains a description of each function in the kernel with complete
details of each function.

It's (Bell Labs flavor) pdp11 assembly language.
