Didb't TOPS-20 also come with sources as > well? Tops-10 was distributed as source because customers were encouraged to add functionality (local monitor commands, for example). TOPS-20 was "perfect as delivered", so source was a separate license fee (and pretty expensive). (At least a source site could compile the files on the tape and get a working monitor, unlike the VMS sources.) Not on Bitsavers, but Trailing Edge has Tops-10 and TOPS-20 source tape images at http://pdp-10.trailing-edge.com/ .
