When formatting a blank 5¼ disk on an 8-bit Apple II using the
INIT command, was there only ever one variation of the boot sector code that was written, or was it updated from time to time over the years?
I'm interested in identifying all the standard boot sectors apart from any customized ones so if there were more than one standard variation I'd like to find a list of the changes from version to version.
For the purposes of this question I'm not asking about ProDOS or 3½ inch disks. For now I'm only asking about the first sector of the first track, not other sectors that are written to during the
INIT process. Also I'm aware that some bytes such as the volume ID probably change from disk to disk.
