Hi there I saw your post as a result of my search criteria in google, i am chasing any and all documentation on DEC LA 120 and any other relevant PDP material. I have just secured a position with a company that supports this type of hardware, and am having difficulty wrapping my mind around the sheer immensity of the equipment. So any help would be very much appreciated, as i search and search for any documentation. :) Best regards Mark Setter
