Fred, all the machines you mention (Apple, Atari, Commodore, Radio Shack)
included schematics and ROM source code listings with their machines, or
at least the machines that were contemporary with the IBM PC. Well, the
Radio Shack might be the exception, as I believe you had to specially
order them. But I know that the Apple ][ Users Manual had a complete
schematic, description, and ROM source listings, and it came with every
Apple ][ and ][+. With the //e you had to order those volumes separately.
