<sect>Binary format<p>
The standard binary file format generated by the linker for the
-Apple ][ target is a binary program with a 4 byte DOS 3.3 header
-containing the load address and load length. The default load address is
-$803.
+Apple ][ target is an <url name="AppleSingle"
+url="http://kaiser-edv.de/documents/AppleSingle_AppleDouble.pdf"> file.
+The default load address is $803.
-<bf/AppleCommander 1.3.5/ or later (available at <url
-url="http://applecommander.sourceforge.net/">) includes the option <tt/-cc65/
-that allows to put binary files with a DOS 3.3 header onto disk images
-containing DOS 3.3 as well as ProDOS 8.
-
-For ProDOS 8 system programs the load address is fixed to $2000 so there
-is no need for a header. Thus the linker configuration
-<ref id="apple-sys-cfg" name="apple2-system.cfg"> for those programs
-omits the DOS 3.3 header. The right AppleCommander option to put system files
-without a header on a ProDOS 8 disk image is <tt/-p/.
+<bf/AppleCommander 1.4.0/ or later (available at <url
+url="https://applecommander.github.io/">) includes the option <tt/-as/ that
+allows to put AppleSingle files onto disk images containing DOS 3.3 as well
+as ProDOS 8.

Using LOADER.SYSTEM is as simple as copying it to the ProDOS 8 directory of the
program to load under name <program>.SYSTEM as a system program. For
-example the program <tt/MYPROG/ is loaded by <tt/MYPROG.SYSTEM/.

<tag/Interrupts/
There's no <tt/interruptor/ support. Any attempt to use it yields the message
'FAILED TO ALLOC INTERRUPT' on program startup. This implicitly means that
- joystick, mouse and RS232 device drivers are not functional as they depend on
- interrupts.
