Memory Map for IIe (64K & 128K versions?)

["Wraithe" <wraithe@datasync.com>]

Does anyone have, or know of, a memory map for the various incarnations of
the IIe?  I'm specifically interested in where screen memory starts (text &
graphics), keyboard, joystick, serial port, etc.  I used to have all this
stuff 15 years ago, on carefully noted handwritten sheets--I was in high
school & too poor to afford the manuals, so I copied down anything I could
find.  I don't really need a hardcopy--actually, an electronic copy or
web-site with the info would be great!

I've searched the net for anything along these lines, but have come up
empty.  And I've seen various books for sale, but haven't a clue as to which
one has the information I'm looking for.

Can anyone please help?

Thanks,
