There are a few places on the internet
in which you can obtain the schematic for
the IIGS. (ASIMOV, 1000bit.it etc)
This is not published in any IIGS that
I currently have find and it is leaving me
with questions.
I would like to find out the abbreviations
/terminology on the schematics of the chips
so I can trace the individual lines.
I would like also to compare ROM01 and ROM3.
Did Apple do this on purpose as it used more
inhouse custom chips as not to have information
readily available?
As the schematics are available, surely there
must be other documentation to go with it.
The IIgs hardware reference should have most of what you're looking for. I believe the 2nd edition includes both the ROM 1 and 3
You are right!!!
It does have the schematic diagram in the Addedum
section at the back.
The only problem with the PDF I have is
that it is missing from the book.
Can you forward/upload a scan of this section?
Wish and Wayne,
you know, what amazes me is the fact
that SAM's never put out a Computerfacts
for the IIgs.
I would Love to get my hands on that.

you should be able to find it here http://apple2.gs/library.php
Apple IIgs Hardware Reference (2nd ed.) 256K Schematic
and
Apple IIgs Hardware Reference (2nd ed.) 1MB Schematic

You did not read my post. Same situation.

Yes I agree. I was also curious as to
why Jim Sather did not also do the
same and release Understanding the IIGS.
It would of been beneficial.
I have since discovered a book which has
escaped my attention.
Apple IIGS Technical Reference by Michael Fischer
At 700 pages it looks promising.
Not on the usual Apple websites. Anyone have
a scan/PDF they care to upload?
sorry I did misread your original post
Can anyone confirm/have a look in a physical/
real book of Apple IIGS Hardware Reference
in the Addendum section. What does it contain?
A schematic of the IIGS and/or is there more
pages/documents.
And it's probably not accidental that it's missing.
There's a guy who has PDFs of old camera manuals on his web site but intentionally removes the troubleshooting sections of those manuals. (Ask me how I know)
There are some really twisted people out there... :~
(and don't get me started on the people who watermark the scans as if they own the material)

And how do you know?
