- C64 RAM Map (Microsoft/Commodore)
-
- The labels and descriptions have been taken from
- Microsoft's original BASIC for M6502 source
- and
- The original C64 KERNAL source by Commodore (901227-03)
- https://github.com/mist64/cbmsrc
-
- Converted and formatted by Michael Steil <mist64@mac.com>

- Corrections (typos as well as content), translations etc.

# This plain text file is formatted so that it can be automatically
# parsed in order to create cross-references etc.
# * Lines starting with "-" is top-level information. The first line
# is the title. Lines starting with "--" are separators.
# * Lines starting with "#" are internal comments.
# * Hex addresses start at column 0.
# * Symbols start at column 13.
# * The description starts at column 21.
# * All lines of the description until the first blank line are
# combined into the heading.
# * A '.' character at the end of a heading line represents a hard
# line break.
# * The remaining text is in MarkDown format.
# * All addresses are 4 digits and have a leading '$'.
# The encoding is UTF-8.
