[pups] bitsavers document

[Martin Lovick]

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). The strange thing is that all of the source code
appears to be in assembler...

whats this about?

is it a comentary of PDP-7 unix?

regards

Martin

Can you give a full URL for this document?  I've taken a brief look at
the list in http://bitsavers.org/pdf/, but nothing jumped out at me.

a few people have responded indicating that this is
the first verion of unix ported to the pdp11 because
the assembler is pdp11.

It is a fairly early version, with commentary, of PDP-11 Unix (the kernel),
indeed still in assembler.  It is an interesting find, probably
the earliest version yet unearthed.  Kossow told me about
it when he did (or got) the scan of the document.

I can't remember receiving it at the time.

It is clearly different from what we in the research
group were running at the time--it has devices we didn't have,
and I think by then we were on the 11/45.

No, not Lions. The author is listed on the first page as one T. R.  
Bashkow.

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.

A quick googling shows a "T.R. Bashkow" writing computing- and
electronic-related papers from 1958 to 1990 or so...
