PDP-7's were used by Thompson and his team on either or all of PDP7 machines #3, #34, #44 or or PDP-7A #149. Thompson and Ritchie bought a PDP-11 in 1971 for $65,000, using it to finalise UNIX using C, after using Fortran and BCPL or B (which evolved into C) as their code, see - http://www.linfo.org/pdp-7.html The second photo is of a PDP-11 from around 1971/2 or so.

I have a site dedicated to the PDP-7 here - http://www.soemtron.org/pdp7.html - including a customer list of the known 99 machines from the 120 systems that were built. Your photo was taken by either Tore or Alberto Gonzalez Iniesta who took the photos on tore's website. I'm afraid the photo Columbia have used is of Tore's machine as it is probably the only good photo of a PDP-7 existing on the web. Columbia’s machine is not in the 99 on the list so is probably one of the 21 unknown machines.

Long story short, we (PictureBubbles°) shoot the panoramas with fisheye lenses in high dynamic range. Much less time is spent shooting than in post-production! There are some other great shots scattered throughout the examples page and the blog, but I wanted to share that one shot here because of the nutty old computer equipment. Reminded me of HAL 9000 with *all* the Kubrick removed. :) Thanks for the props guys (and sorry for the shameless self-promotion on your blog, Scott)!
