<sect>Binary format<p>
The output format generated by the linker for the KIM-1 target is a raw binary BIN file, which
is essentially a memory image. You can convert this to a papertape format file using
Convert8bithexformat or KIMPaper, which are open-source conversion utility programs.
A papertape format files can be transferred to the KIM-1 using the RS-232 terminal port (TTY),
just as if the machine-code was entered by hand. Enter 'L' in the TTY and start the paper tape file

The ROMs and I/O areas are defined in the configuration files, as are most of the entry points
for useful subroutines in the KIM-1 monitor ROM. cc65 generated programs compiled and linked
using 4k config run in the memory range of &dollar;200 - &dollar;0FFF. The 60k config expands
this range to &dollar;DFFF. The starting memory location and entry point for running the program is
&dollar;200, so when the program is transferred to the KIM-1, it is executed by typing '200 G'.
