"This formatting was created by an unpublished tool by David T. Craig, who published a lot of Apple-related soure code (Apple II, Apple III, Lisa) in this format in as early as 1993, first anonymously, later with his name). The filename “david mac g5 b:m6502.asm” (disk name “david mac g5 b”, file name “m6502.asm”, since it was a classic Mac OS tool) confirms David Craig’s involvement, and it means the line numbers were added no earlier than 2003. Given all this, it is safe to assume the file with the Microsoft BASIC for 6502 source originated at Apple, and was given to David Craig together with the other source he published. The version I posted is a reconstruction of the original file, with the header, the footer and the line numbers removed, and the spaces converted back into tabs. I chose the name “M6502.MAC” to be consistent with the MACRO-10 file extension used by the Microsoft BASIC for 8080 sources."
