[TUHS] The first PDP-7 running Unix

In honor of the Unix 50 party tomorrow, I wrote an analysis of the
available data to conclude the first PDP-7 that Ken and Dennis used to
bring up Unix on was serial number 34. I've not seen this result elsewhere,
but if it's common place, please let me know.


One surprise from the analysis: there was only one pdp-7 in the world that
could have run the original v0 unix. It's the only one that had the RB09
hard drive (though the asset list referenced in the article listed a RC09
on that system).

I hope you enjoy
