Lots of good books here:

I don't want to go through the trouble to download several books in
search of one with the kernal map. Which one(s) contain the info?
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.
