osd-contiki/platform/apple2enh/linker.cfg

# This file should be identical to the file '<cc65>/doc/apple2.cfg' with the
# following exceptions:
# - Reduced stacksize: Contiki is designed to use extremely little stack.
#   The applications coming with Contiki run even with a $100 byte stack.
# - Expanded RAM size: Allow applications to overlay BASIC.SYSTEM if needed.
#   In that case the binary must be loaded with the ProDOS 8 loader available
#   at: ftp://ftp.musoftware.de/pub/uz/cc65/contrib/loader-1.4.zip
# - Expanded LC size: Allow applications to overlay the ProDOS 8 QUIT code.
#   In that case the binary must reboot on exit. There's a ProDOS 8 loader
#   variant available at the URL above that does just this.
