Requires Python: >=3.6,<4.0
Keywords: Emulator,6809,Dragon,CoCo,Vectrex,tkinter,pypy

--------------------------------------
Dragon/CoCO emulator written in Python
--------------------------------------

DragonPy is a Open source (GPL v3 or later) emulator for the 30 years old homecomputer ``Dragon 32`` and ``Tandy TRS-80 Color Computer`` (CoCo)...

The `MC6809 <https://github.com/6809/MC6809>`_ project is used to emulate the 6809 CPU.

(Note: Python 2 support was removed)

DragonPy is written in Python.
It's platform independent and runs with Python and PyPy under Linux/Windows/OSX/...
It's tested with Python 3.x, PyPy

DragonPy will not be a second XRoar written in Python.
This project is primarily to lean and understand.

Future goals are:

* Implement a integrated development environment for BASIC programs

A full featured Dragon / CoCo emulator is `XRoar <http://www.6809.org.uk/dragon/xroar.shtml>`_.

Current state
=============

The Dragon 32 / 64 and CoCo ROMs works in Text mode.
Also the "single board computer" ROMs sbc09, Simple6809 and Multicomp6809 works well.

There is a rudimentary BASIC editor with save/load BASIC programm listings direct into RAM.

Looks like this:

|old screenshot BASIC Editor|
(older version of the editor)

.. |old screenshot BASIC Editor| image:: https://raw.githubusercontent.com/jedie/jedie.github.io/master/screenshots/DragonPy/20140820_DragonPy_BASIC_Editor_01.png

Vectrex
-------

The `Vectrex (Wikipedia) <https://en.wikipedia.org/wiki/Vectrex>`_ is a vector display-based video game console.
The Hardware are *only* the 6809 CPU, a 6522 Versatile Interface Adapter and the AY-3-8912 sound chip.

Current state is completely not usable. The 6522 is only a dummy implementation.
It makes only sense to display some trace lines, e.g.:

::

    .../DragonPy$ poetry run DragonPy --verbosity 0 --machine=Vectrex run --trace --max_ops=1

BASIC Editor
============

Use "BASIC editor / open" in the main menu to open the editor.

You can load/save ASCII .bas files from you local drive or just type a BASIC listing ;)
With "inject into DragonPy" you send the current listing from the Editor to the Emulator and with "load from DragonPy" back from emulator to editor.
Note: The is currently no "warning" that un-saved content will be "overwritten" and there is no "auto-backup" ;)

The "renumbering" tool can be found in the editor window under "tools"

You can also run the BASIC Editor without the Emulator:

::

    .../DragonPy$ make editor
    # or:
    .../DragonPy$ poetry run DragonPy editor

A rudimentary BASIC source code highlighting is available and looks like this:

|screenshot BASIC Editor|

.. |screenshot BASIC Editor| image:: https://raw.githubusercontent.com/jedie/jedie.github.io/master/screenshots/DragonPy/20140826_DragonPy_BASIC_Editor_01.png

Special feature: The Line number that are used in GOTO, SOGUB etc. are extra marked on the left side.

install in virtualenv by foot:
==============================

e.g.:

::

    # Create virtualenv:
    .../$ python3 -Im venv DragonPy
    
    # activate created virtualenv:
    .../$ cd DragonPy
    .../DragonPy$ source bin/activate
    
    # update pip before install:
    (DragonPy) .../DragonPy$ pip install -U pip
    ...
    
    # Install DragonPy:
    (DragonPy) .../DragonPy$ pip install DragonPyEmulator
    Collecting DragonPyEmulator
    ...
    Installing collected packages: click, six, dragonlib, pygments, MC6809, DragonPyEmulator
    Successfully installed DragonPyEmulator-0.5.3 MC6809-0.5.0 click-6.7 dragonlib-0.1.7 pygments-2.2.0 six-1.11.0
    
    # start Emulator
    (DragonPy) .../DragonPy$ DragonPy

Windows
=======

There are several ways to install the project under windows.

The following is hopeful the easiest one:

* Install Python 3, e.g.: `https://www.python.org/downloads/ <https://www.python.org/downloads/>`_

* Download the ``DragonPy`` git snapshot from Github: `master.zip <https://github.com/jedie/DragonPy/archive/master.zip>`_

* Extract the Archive somewhere

* Maybe, adjust paths in ``boot_dragonpy.cmd``

* Run ``boot_dragonpy.cmd``

The default ``boot_dragonpy.cmd`` will install via ``Python Package Index`` (PyPi) into ``%APPDATA%\DragonPy_env``

start DragonPy
--------------

The is a simple "starter GUI", just call the cli without arguments:

``%APPDATA%\DragonPy_env\Scripts\DragonPy.exe``

It looks like this:

---------
run tests
---------

You can run tests with PyPy, Python 2 and Python 3:

::

    ~/DragonPy$ make pytest
    # or:
    ~/DragonPy$ make tox
    # or:
    ~/DragonPy$ poetry run pytest

.. |screenshot simple6809| image:: https://raw.githubusercontent.com/jedie/jedie.github.io/master/screenshots/DragonPy/Simple6809_TK_04.PNG

Dragon Keyboard
===============

The keyboard mapping is stored into `dragonpy/Dragon32/keyboard_map.py <https://github.com/jedie/DragonPy/blob/master/dragonpy/Dragon32/keyboard_map.py>`_.

Some notes:

* "CLEAR" is mapped to "Home" / "Pos 1" key

* "BREAK" is mapped to "Escape" button

* "LEFT" is mapped to left cursor key and to normal backspace, too.

A "auto shift" mode is implemented. So normal lowercase letters would be automaticly converted to uppercase letters.

paste clipboard
---------------

It is possible to paste the content of the clipboard as user input in the machine.
Just copy (Ctrl-C) the follow content:

::

    10 CLS
    20 FOR I = 0 TO 255:
    30 POKE 1024+(I*2),I
    40 NEXT I
    50 I$ = INKEY$:IF I$="" THEN 50

Focus the DragonPy window and use Ctrl-V to paste the content.

Looks like:

performance
===========

The current implementation is not really optimized.

With CPython there is round about 490.000 CPU cycles/sec. in console version.
This is half as fast as the real Hardware.

With PyPy round about 6.900.000 - 8.000.000 CPU cycles/sec.
In other words with PyPy it's 8 times faster as the real Hardware.

e.g. The Dragon 32 6809 machine with a 14.31818 MHz crystal runs with:
0,895MHz (14,31818Mhz/16=0,895MHz) in other words: 895.000 CPU-cycles/sec.
