Do modern companies (Dell, Compaq, Cisco, Sun, etc.)
even still
publish the big old installation planning guides like IBM did (and
still does)? The ones I have seen look like afterthoughs written on
the back of a gum wrapper.
Not sure about this, but I keep one IBM manual with the specifications of
the technical floor of our DataCenter. It appears to be standard and not
special for us. And I retired it from the dumpster two years ago, together
with some old DOS/VS, CICS, DL/I and PL/I manuals.
