What is in picture 18? There is something very familiar with it. To me it looks like the backplane of a PDP-9. The core memory stack in the top. Compare with the RICM PDP-9: http://www.ricomputermuseum.org/Home/equipment/dec-pdp-9/PDP-9_Processor_Front.jpg I would be very interesting to see more pictures of the cabinet in picture 18. I also would guess that the the cabinet with the A/D converter (AF01A) in the top also hold a D/A converter (AA01A). It looks very much similar to the one we have with our PDP-9. https://dl.dropboxusercontent.com/u/96935524/Datormusuem/Exhibhall-8l-8e-rk07.png (the cabinet next to the RK07) /Mattis
