## Dragon/CoCO emulator written in Python
DragonPy is a Open source (GPL v3 or later) emulator for the old (1981) 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.

Dragon 32 with CPython 3 under Linux:
Tandy TRS-80 Color Computer 2b with CPython 2 under Windows:
(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:
(older version of the editor)
#### 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:
Special feature: The Line number that are used in GOTO, SOGUB etc. are extra marked on the left side.
## installation
IMPORTANT: The **PyPi package** name is **DragonPyEmulator** and [not only "DragonPy"](https://github.com/jpanganiban/dragonpy/issues/3)!!!
```
pip install DragonPyEmulator
```

## ROMs
All needed ROM files, will be **downloaded automatically**.
The files will be downloaded from:
| Machine | download url |
|----------------|--------------|
| Dragon 32 + 64 | [http://archive.worldofdragon.org/archive/index.php?dir=Software/Dragon/Dragon%20Data%20Ltd/Dragon%20Firmware/](http://archive.worldofdragon.org/archive/index.php?dir=Software/Dragon/Dragon%20Data%20Ltd/Dragon%20Firmware/) |

### Dragon Keyboard
The keyboard mapping is stored into [dragonpy/Dragon32/keyboard_map.py](https://github.com/jedie/DragonPy/blob/main/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:
Then just **RUN** and then it looks like this:

### 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.
## TODO:
* implement more Dragon 32 periphery
* missing 6809 unittests after coverage run:
* `MUL`
* `BVS`

"description": "## Dragon/CoCO emulator written in Python\n\nDragonPy is a Open source (GPL v3 or later) emulator for the old (1981) homecomputer `Dragon 32` and `Tandy TRS-80 Color Computer` (CoCo)...\n\nThe [MC6809](https://github.com/6809/MC6809) project is used to emulate the 6809 CPU.\n\n[](https://github.com/jedie/DragonPy/actions/workflows/tests.yml)\n[](https://app.codecov.io/github/jedie/dragonpy)\n[](https://pypi.org/project/DragonPyEmulator/)\n[](https://github.com/jedie/DragonPy/blob/main/pyproject.toml)\n[](https://github.com/jedie/DragonPy/blob/main/LICENSE)\n\n\nDragon 32 with CPython 3 under Linux:\n\n![screenshot Dragon 32](https://raw.githubusercontent.com/jedie/jedie.github.io/master/screenshots/DragonPy/20150820_DragonPy_Dragon32_CPython3_Linux_01.png \"screenshot Dragon 32\")\n\nTandy TRS-80 Color Computer 2b with CPython 2 under Windows:\n\n![screenshot CoCo under Windows](https://raw.githubusercontent.com/jedie/jedie.github.io/master/screenshots/DragonPy/20150820_DragonPy_CoCo2b_CPython2_Win_01.png \"screenshot CoCo under Windows\")\n\n(Note: Python 2 support was removed)\n\nDragonPy is written in Python.\nIt's platform independent and runs with Python and PyPy under Linux/Windows/OSX/...\nIt's tested with Python 3.x, PyPy\n\nDragonPy will not be a second XRoar written in Python.\nThis project is primarily to lean and understand.\n\nFuture goals are:\n\n\n* Implement a integrated development environment for BASIC programs\n\nA full featured Dragon / CoCo emulator is [XRoar](http://www.6809.org.uk/dragon/xroar.shtml).\n\n### Current state\n\nThe Dragon 32 / 64 and CoCo ROMs works in Text mode.\nAlso the \"single board computer\" ROMs sbc09, Simple6809 and Multicomp6809 works well.\n\nThere is a rudimentary BASIC editor with save/load BASIC programm listings direct into RAM.\n\nLooks like this:\n\n![old screenshot BASIC Editor](https://raw.githubusercontent.com/jedie/jedie.github.io/master/screenshots/DragonPy/20140820_DragonPy_BASIC_Editor_01.png \"old screenshot BASIC Editor\")\n(older version of the editor)\n\n#### Vectrex\n\nThe [Vectrex (Wikipedia)](https://en.wikipedia.org/wiki/Vectrex) is a vector display-based video game console.\nThe Hardware are _only_ the 6809 CPU, a 6522 Versatile Interface Adapter and the AY-3-8912 sound chip.\n\nCurrent state is completely not usable. The 6522 is only a dummy implementation.\nIt makes only sense to display some trace lines, e.g.:\n```\n.../DragonPy$ poetry run DragonPy --verbosity 0 --machine=Vectrex run --trace --max_ops=1\n```\n\n### BASIC Editor\n\nUse \"BASIC editor / open\" in the main menu to open the editor.\n\nYou can load/save ASCII .bas files from you local drive or just type a BASIC listing ;)\nWith \"inject into DragonPy\" you send the current listing from the Editor to the Emulator and with \"load from DragonPy\" back from emulator to editor.\nNote: The is currently no \"warning\" that un-saved content will be \"overwritten\" and there is no \"auto-backup\" ;)\n\nThe \"renumbering\" tool can be found in the editor window under \"tools\"\n\nYou can also run the BASIC Editor without the Emulator:\n```\n.../DragonPy$ make editor\n# or:\n.../DragonPy$ poetry run DragonPy editor\n```\n\nA rudimentary BASIC source code highlighting is available and looks like this:\n\n![screenshot BASIC Editor](https://raw.githubusercontent.com/jedie/jedie.github.io/master/screenshots/DragonPy/20140826_DragonPy_BASIC_Editor_01.png \"screenshot BASIC Editor\")\n\nSpecial feature: The Line number that are used in GOTO, SOGUB etc. are extra marked on the left side.\n\n## installation\n\nIMPORTANT: The **PyPi package** name is **DragonPyEmulator** and [not only \"DragonPy\"](https://github.com/jpanganiban/dragonpy/issues/3)!!!\n```\npip install DragonPyEmulator\n```\n\n### from source\n\n```bash\n~$ git clone https://github.com/jedie/DragonPy.git\n~$ cd DragonPy/\n~/DragonPy$ ./cli.py --help\n```\n\nThe output of `./cli.py --help` looks like:\n\n[comment]: <> (\u2702\u2702\u2702 auto generated main help start \u2702\u2702\u2702)\n```\nUsage: ./cli.py

\"BREAK\" is mapped to \"Escape\" button\n* \"LEFT\" is mapped to left cursor key and to normal backspace, too.\n\nA \"auto shift\" mode is implemented. So normal lowercase letters would be automaticly converted to uppercase letters.\n\n#### paste clipboard\n\nIt is possible to paste the content of the clipboard as user input in the machine.\nJust copy (Ctrl-C) the follow content:\n```\n10 CLS\n20 FOR I = 0 TO 255:\n30 POKE 1024+(I*2),I\n40 NEXT I\n50 I$ = INKEY$:IF I$=\"\" THEN 50\n```\n\nFocus the DragonPy window and use Ctrl-V to paste the content.\n\nLooks like:\n\n![raw.githubusercontent.com/jedie/jedie.github.io/master/screenshots/DragonPy/20140805_DragonPy_Dragon32_Listing.png](https://raw.githubusercontent.com/jedie/jedie.github.io/master/screenshots/DragonPy/20140805_DragonPy_Dragon32_Listing.png \"https://raw.githubusercontent.com/jedie/jedie.github.io/master/screenshots/DragonPy/20140805_DragonPy_Dragon32_Listing.png\")\n\nThen just **RUN** and then it looks like this:\n\n![raw.githubusercontent.com/jedie/jedie.github.io/master/screenshots/DragonPy/20140805_DragonPy_Dragon32_CharMap.png](https://raw.githubusercontent.com/jedie/jedie.github.io/master/screenshots/DragonPy/20140805_DragonPy_Dragon32_CharMap.png \"https://raw.githubusercontent.com/jedie/jedie.github.io/master/screenshots/DragonPy/20140805_DragonPy_Dragon32_CharMap.png\")\n\n### DragonPy schematic\n```\n Main Thread Sub Thread\n (Tkinter GUI)\n +------------------+ +---------------------+\n | | | |\n | +-------------+ | CPU cycles/sec queue | |\n | | <------------------------------------+6809 CPU |\n | | | | | + ^ |\n | | GUI | | | | | |\n | | | | Display RAM write queue | +--v-----+--+ |\n | | .--------------------------------------------+ Memory | |\n | | | | | | +--+-----^--+ |\n | | | | | | | | |\n | | | | | | +-----v-----+-----+ |\n | | | | | | | Periphery | |\n | | | | | Keyboard queue | | MC6883 SAM | |\n | | | +--------------------------------->MC6821 PIA | |\n | | | | | | | | |\n | +--+-----^----+ | | | | |\n | | | | | +-----------------+ |\n | | | | | |\n | +--v-----+----+ | | |\n | | | | | |\n | | Display | | | |\n | | | | | |\n | +-------------+ | | |\n +------------------+ +---------------------+\n\n```\n\n### performance\n\nThe current implementation is not really optimized.\n\nWith CPython there is round about 490.000 CPU cycles/sec. in console version.\nThis is half as fast as the real Hardware.\n\nWith PyPy round about 6.900.000 - 8.000.000 CPU cycles/sec.\nIn other words with PyPy it's 8 times faster as the real Hardware.\n\ne.g. The Dragon 32 6809 machine with a 14.31818 MHz crystal runs with:\n0,895MHz (14,31818Mhz/16=0,895MHz) in other words: 895.000 CPU-cycles/sec.\n\n## TODO:\n\n\n* implement more Dragon 32 periphery\n* missing 6809 unittests after coverage run:\n * `MUL`\n * `BVS`\n\n## PyDragon32\n\nSome `Python`/`BASIC tools`/`scripts` around `Dragon32/64` / `CoCo` homecomputer.\n\nAll script are copyleft 2013-2020 by Jens Diemer and license unter GNU GPL v3 or above, see LICENSE for more details.\n\n### Python scripts:\n\n\n* PyDC - Convert dragon 32 Cassetts WAV files into plain text:\n * [github.com/jedie/DragonPy/tree/master/PyDC](https://github.com/jedie/DragonPy/tree/master/PyDC)\n* Filter Xroar traces:\n * [github.com/jedie/DragonPy/tree/master/misc](https://github.com/jedie/DragonPy/tree/master/misc)\n\n### BASIC programms:\n\n\n* Simple memory HEX viewer:\n * [github.com/jedie/DragonPy/tree/master/BASIC/HexViewer](https://github.com/jedie/DragonPy/tree/master/BASIC/HexViewer)\n\n\n* Test CC Registers:\n * [github.com/jedie/DragonPy/tree/master/BASIC/TestCC_Registers](https://github.com/jedie/DragonPy/tree/master/BASIC/TestCC_Registers)\n\n#### Input/Output Tests\n\n[/BASIC/InputOutput/keyboard.bas](https://github.com/jedie/DragonPy/tree/master/BASIC/InputOutput/keyboard.bas)\nDisplay memory Locations $0152 - $0159 (Keyboard matrix state table)\n\nExample screenshow with the \"Y\" key is pressed down.
