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.

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.
