Changes
/* File Headers */
Cassette files are subdivided into 2K blocks, each of which is preceded by a 64-byte header.
AMSDOS files are usually stored with a 128-byte [[AMSDOS Header]] (based on cassette header) but can also be headerless, depending on the contents of the file. Unprotected ASCII files do not have header.
CP/M files do not have headers.
