Oric Telestrat is the last Oric computer (Released in 1986, mainly in France).
This computer is an Atmos with extra hardware: RS232, cardridge(banking system),
joysticks (2 ports) or mouse (on joystick port), FDC.
Video chip, CPU, keyboard management, tape hardware are the same than Atmos.
Telestrat can start in Atmos mode with Atmos Cardridge (which is only the atmos
Basic 1.1 ROM).
Telestrat can start in Sedoric (Atmos OS) and Atmos mode with Stratoric Cardridge.
This Cardridge has 3 banks of 16KB of rom with:
<itemize>
<item>a Sedoric ROM.
<item>a Basic 1.1 ROM (Atmos).
<item>a Basic 1.0 ROM (Oric-1).
</itemize>
The main Telestrat's configuration is the Telemon/Hyperbasic Cardridge inserted
with Stratsed in floppy drive.
Anyway, there is no way to load a tape file in Telemon/Hyperbasic mode without
alternative program.
There is also no software to write a Stratsed dsk file on PC.
This Telestrat target build an Orix binary file. But, in the future, it will be possible
to build a Stratsed disk. Orix uses the same systems calls than Telemon mode.
That is why if you need to do software for telestrat target, you have the choice to:
<itemize>
<item>use cc65 Atmos target and start Telestrat in Atmos mode: A tape file is required.
<item>use cc65 Atmos target and start Telestrat in Stratoric mode: A dsk file or tape file is required.
<item>use cc65 Telestrat target and start Telestrat in Orix mode (see <url
name="here" url="http://orix.oric.org/download/">).
<item>use cc65 Telestrat target, remove Orix header from binary, code a dsk tool for Stratsed,
add Stratsed header on your binary,insert your binary on floppy disk (this solution will be possible is the future).
</itemize>
Telestrat (from cardridge) can handle 8 banks (from $C000 to $FFFF): Bank 0 is the overlay ram. Others banks can be ROM or RAM.
<sect>Binary format<p>
The standard binary output format generated the linker for the Telestrat
target is a machine language program with a 20 bytes header described <url
name="here" url="http://orix.oric.org/doku.php?id=orix:header">
name="here" url="http://orix.oric.org/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 easily.
