The standard binary output format generated the linker for the Telestrat target
|
||||
is a machine language program with a 20 bytes header described here : http://orix.oric.org/doku.php?id=orix:header
|
||||
|
||||
This header is used for Telemon 3.0.
|
||||
|
||||
Anyway, for Telemon 2.4, there is no file management, there is no TAPE routine in telemon, there is no way to load a binary easiy.
|
||||
|
||||
Stratsed (the Telestrat operating system) handles files management. Stratsed is loaded to memory from floppy disk.
|
||||
|
||||
There is no tool to insert a binary in a Stratsed floppy disk.
|
||||
|
||||
The only way to load a binary (for Telemon 2.4) is to :
|
||||
<itemize>
|
||||
<item>remove the 20 bytes header
|
||||
<item>download osdk : http://osdk.defence-force.org/index?page=download
|
||||
<item>use Floppybuilder in OSDK to insert the binary with the tool (please read FloppyBuilder manual to insert your binary, and to start microdisc boot sector when telestrat starts)
