Is there such a book? If there is, where can I get it online in .PDF format? I tried Google but couldn't find it. :(

BTW, I'm asking so I can add PET support to CBMSimpleIO.

I tried to help but failed. I was thinking what you are looking for is
called "firmware" or "kernal routines", but both web searches only showed
up the link already posted queering with "PET" and ended up at a dead end
otherwise.
For the Commodore 64 on the other hand they are easily to find.
If everything else fails, look through archive.org for "PET
Gazette". Suppose this magazine got to have covered them at some point in
the late 70s, being a purely PET focused magazine at that time.
Without opening a new thread. You could have a "PC speaker" sound on the
PET. No idea if this was widely used. But since a lot of the hardware was
imported to all other 8Bit Commodore computers following the PET you
could have it there too, by connecting some pins from the user- (or
expansion?) port to an external speaker. But no one really did this
because starting with the VIC-20 you had a dedicated sound chip built in.

I would heartily recommend Raeto West's "Programming the Commodore PET" as well as his similarly titled works for the VIC-20 and C=64, all easily found in pdf

I have both of West's books and the most detailed of the two is the one
on the PET (a lot of the stuff also applies to the C-64). For
specifically a C-64, his book dedicated to that platform is the best
I've ever seen for an "under the hood" look at C-64 architecture and
operation. For something akin to that detail you probably have to
browse through the Transactor mag issues. Commodore's Programmer's
Reference is also good but hardly a complete look. Keep in mind these
books are dedicated to the main platform, not peripherals like the 1541
disk drive (an exception is game/exrom cart operation). IIRC Jim
Butterfield also produced a detailed C-64 memory map and usage chart but
I'm unsure where that was published. Sincerely,
