023- I have several different model Apple II computers
ranging from a II+ up through a IIgs. Does anyone know
where I can get diagrams for these machines?
I know of three books with Apple ][+ schematics:
Jim Sather's "Understanding the Apple ]["
"The Apple II Circuit Description" by Winston D. Gayler
published by Howard W. Sams & Co (ISBN 0-672-21959-X)
Apple II Reference Manual (1979)

A set of IIgs ROM-01 schematics was published in the September 1999 issue
of GS WorldView. Go to GSWV's Archive at ...

The Apple II Reference Manual (1979) includes a II/II+ schematic, a
keyboard schematic, and annotated firmware listings. For Disk II and Disk II
Controller schematics, see The DOS Manual (1981) from Apple.
For the IIe and enhanced IIe, see the Apple IIe Technical Reference Manual.
The 1986 edition includes diagrams and annotated firmware listings.
The Apple IIc Technical Reference Manual (1987) includes IIc schematics and
firmware listings for the three major IIc versions. A later (1989) "Second
Edition" of the manual includes IIc+ coverage.
The Apple IIgs Hardware Reference has a good set of schematics. The First
Edition covers the ROM-01. The Second Edition covers ROM-01 and ROM 3.
Unfortunately, there is no IIgs firmware listing.
Although most Apple II manuals are out of print, many can still be
purchased from on-line book sellers such as Amazon.com.
On-line, GS Worldview's archive offers a couple folders with several
schematics at http://apple2.org.za/gswv/a2zine/Docs/ .
