This was posted earlier as part of a reply to a specific
question about PETSCII to cbm "screen code" conversions, but I
don't think it made it out of San Diego.
There exists a book, Title: "Inside the Commodore 64"
Author: Milton Bathurst
Publisher: DataCap
12 Trixhai
4545 Feneur
Belgium
Copyright 1983
Price: (I paid) $19.95
which purports, and indeed seems to be, a complete, detailed,
commented and cross-referenced listing of the ROM contents
of the C64. Judging from all the discussion about groping
around inside the ROM, I guess it must not have a wide
distribution. It's fairly poorly printed (but legible) and
worse bound, but it sure beats dissasembling machine code.

The first time this article was posted, somebody posted a followup
question that I never saw answered:
Where in the U.S. can we get it?
Some of us are wary of transoceanic mail.

Regarding the book "Inside the Commodore 64 (tm)", by Milton
Bathurst, published in Europe, which seems to be a complete,
well commented, cross-referenced, and reasonably accurate
listing of the contents of the C-64's ROM:
I purchased it at a place here in San Diego,
Computer Outlet
5857 Mission Gorge Rd.
San Diego, CA 92120
(619) 282-6200
I have no idea if the book is still available, because I haven't been
back there for several months. They advertise the avalilability
of a free catalog in ads in local computer papers.
The only errors I have found so far are in the comments.
In the routines for handling the serial bus, they have
reversed the sense of the various lines; e.g., the
routine which they say sets the serial data line high, actually
sets it low. Apparently they looked only at the code, and
didn't take into account the inverter-buffers which actually drive
the serial lines.
