I have that manual, and it does cover the enhanced IIe.  The included
schematic covers the original board layout, which used eight 64Kx1 DRAM
chips.  My understanding of the last IIes (having never seen inside one
myself) is that the motherboard was redesigned to use two 64Kx4 chips
instead.  That change wouldn't be in the 1985 edition of the tech reference,
but as far as writing software and designing add-on hardware goes, it
wouldn't make any difference.
