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

I see PDP-7 #34 also had these options:
340 Precision incremental CRT display
342 Symbol generator for 340 display, first 64 characters
370 High speed light pen
Was this the display used for Space Travel?
These hardware devices are all supported by Phil Budne's 340 simulation
in SIMH, so if the software was to be found it could probably be run.

That's my belief given how the story was told in the history. But the
histories I've read weren't specific as to whether the stock display was
used or the custom one was.

That's true. The simh machine emulates both, so it wouldn't matter. And
we'd be able to know which one was used... I've not seen the code for this,
though...
