Sifting through the dust of pdp8-lovers, I found this one:

Subject: Unix on the pdp8

I've found an very interesting list in a Unixbook I have, and quot some bits
 from it:

"Just how transportable Unix is can be seen by looking at the wide range of
machines that Unix already runs on. These are currently:

 - Amdahl 470
   ...
 - Digital Equipment Corp. PDP/11
 - Digital Equipment Corp. PDP/7
 - Digital Equipment Corp. PDP/8
   ...". 

Some pages later in the book is another interesting list giving a overview
of what is abailable on the Unix market now:

"System         Type         Machines        Supplier
----------------------------------------------------------------------

Unix            Very real    PDP 11/8/7  VAX     AT & T International
                                                 P.O. Box 7000-8
                                                 Baskin Ridge, New Jersey 07920
                                                 USA
...
"

This is the book that Johnny Billquist talked about before. Is there anyone
that have heard anything about *nix on the PDP-8, r have been  in contact with
it in the real_world?

I assume this book was eventually confirmed to have a typo in it, etc.
Anyone know for sure?

My understanding of early unix is that it first appeared on the -7 and -9
largely as a revolt against the ADSS crap that was DEC's usual system for
those machines, etc.  By implication, this eventually means that it runs
on the PDP-15 as well.  Then it was ported to the -11, and the rest is as
they say .....

So, it might be interesting to trace the path of this misinformation,
since mentioning the -11 sorta forces there to be four machines in that
list, notwithstanding that the PDP-8 isn't one of them!

It seems that pdp8 unix may not be that far off...
it might seem like xinu could be ported to an 8 using the micro-c
compiler as a basis.
micro c compiler for pc execution can be found on oak.oakland.edu
undr pub/msdos/c as mc302xxx.zip

 I checked this out and found that this is a typo.
