whilst looking around the bitsavers.org pdf archive, I
found a document called
PreliminaryUnixImplementationDocument_Jun72.pdf.
Having had a quick scan through, it contains a source
code listing and some commentary (lions i hear you
say).
No, not Lions. The author is listed on the first page as one T. R.
Bashkow.
The strange thing is that all of the source code
appears to be in assembler...
yup. This would be an early pdp11 UNIX from the period before the
rewrite in C.
whats this about?
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.
is it a comentary of PDP-7 unix?
It's (Bell Labs flavor) pdp11 assembly
language.
regards
Martin
