Atlas: Programming the UK's first supercomputer
linuxvoice.comIn the photo with Ann Moffat and her daughter is the 'table' that they are sitting at some sort of punch card setup?
It looks like a way to project a microfilm image onto a table top.
I followed the link and found http://www.chilton-computing.org.uk/gallery/ral/slide3.htm . The bottom-right corner is this image, with the title "Scanning Lab". It's also visible, without a projected image, in the image at the top-left. ( http://www.chilton-computing.org.uk/gallery/ral/orig/r02008.... )
The machine in the background appears to be a digitizer, given the image on the bottom row, center http://www.chilton-computing.org.uk/gallery/ral/orig/r03354.... .
Edit: oops! I pointed to an image from the same photo session, but this Linux Voice article uses the upper-left photo at http://www.chilton-computing.org.uk/gallery/ral/slide4.htm . That is, LV uses http://www.chilton-computing.org.uk/gallery/ral/orig/r03357.... and not http://www.chilton-computing.org.uk/gallery/ral/orig/r03356.... . Note that the Chilton Computing web site dates the images as 26.07.68.
