Yes it would. The 'cold war secrets' site must have had access to a copy but I have no idea if the entire document was scanned
Re: SAGE memory plane
Its a shame it wasn't in the complete unit. Unless someone actually erases it, core memory will hold data until the sun swells up, as a red giant, and toast the earth. One always wonders what one would find on these old cores.

In the T.O. (http://www.bitsavers.org/pdf/ibm/sage/3-32-0_Central_Computer_System_Vol1_Feb59.pdf), that cabinet is called "core memory 1", or 256² ferrite core array". We just called it "Big Mem".

The SAGE was the AN/FSQ-7 computer, possibly the sub-units had some IBM designation, although a quick scan of some bitsavers docs didn't turn that up. The SAGE main system were built on gigantic racks covered with modules with a row of tubes on them. So, no housing as we normally would expect. But, I think the core memory was different, and was built into a housing. I think the memory unit had few tubes in it, needed shielding and probably used controlled temperature, so a housing made more sense. But, that unit definitely matches what the SAGE core memory units looked like. Jon
