Re: Machine that weighs less than its operating manual.
The smallest set were the user manuals, five or six IIRC. Then you had the system managers manual set which was twenty or so, and there was also the programmers' manual set detailing all the system libraries. Never had occasion to actually count those, but they easily took twice the shelf space of the system managers manuals.
On top of that you would have one or more binders for each of the installed products.
