Wayne Stewart did a PDF conversion--not just a scan--of
the manual for the Apple II Programmers Aid ROM. There
are a few typographical errors but it is very good.
It is about 278KB. E-mail me if you want a copy.
The empty ROM socket in the Apple II at addresses $D800-$DFFF
never had an official Apple ROM but there were some third party
ROMs such as the Inspector and the Senior PROM. In the Integer
BASIC disk file on the DOS 3.3 system masters that area is
filled with the Applesoft BASIC code from the same range of
addresses.

Someplace in my office I have a old program by Laser Systems that
reads the rom and makes a "clean" commented disassembly listing of
it. Randy Hyde wrote it as a kind of exercise for his disassembler,
so its pretty complete as I remember with proper variable names etc.
Apple didn't let it stay long on the market though.

I presume by "disassembly listing of it" you are referring to Integer
BASIC. There's no need to disassemble Programmer's Aid #1 as the source
listings are in the manual.
There are some errata/patches to Programmer's Aid #1. I don't have the
printed information, and I'm not sure whether the patches were applied
to the version in the INTBASIC file.

I think it was a disassembly listing of all the roms in a Apple II,
it was called something revealed, maybe dos, or maybe I don't
remember and now need to poke all over my office looking for it.

Was there ever a Programmer's Aid #2 (or 3? or 0?)

What kind of "comments" can it make on the disassembly??
; loads the Accumulator with $#00
; jumps to location $0800

Randy Hyde liked tools, and LISA, the Laser Interactive Symbolic
Assembler, was his favorite to mess with, so when he added
disassembly to it, he made it so that you could quickly go back and
forth between source code and binary files, with all the comments etc
preserved. How I think it worked was to have 3 files, Source, binary,
and essentially all the text you need to go from binary back to
source. Over a LONG period of time Randy made his own version of the
ROM source files, and made them as accurate as he could using the
same subroutine names and variables as Apple used internally (that he
could find out). Randy's version of the source files may well have
been better and more accurately documented than what Apple had
internally.
He knew he could never get away with selling a full commented etc
listing of the Roms, but figured selling a program that would
disassemble them on the owners own machine and print out the results
with comments etc. would be OK. Apple didn't see it that way.
