Great!

Thanks for the information, that's help me much. I will implement this soon. But currently i working to limit the Speed to realtime: https://github.com/jedie/DragonPy/compa ... ...df7eaeb

I would like to implement IRQ in DragonPy, so that the TIMER will work. I have looked into "Inside the Dragon": There is no page 193: The Dragon does not use all the M6809's interrupts but only makes use of the IRQ and FIRQ interrupts. and on page 197: The normal interrupt (IRQ) is derived from the ...

Here's an interrupt driven (IRQ) real-time-clock that you can use in your own BASIC programs. The machine code routine is position independent and DragonDOS compatible. 200 DATA 1A,50,30,8D,0,12,BC,1,D,27,A,FC,1,D,BF,1,D,ED,8D,0,35,1C,AF,39,96,FC 210 DATA 4C,81,31,25,28,F,FC,96,FD,4C,81,3C,25,1B,F,...

I have done some simple performance optimization... I Implement pause/resume, hard-/soft-reset 6809 in GUI and improve a little the GUI/Editor stuff: http://www.jensdiemer.de/static/jensdiemer.de/screenshots/20140905_DragonPy_Dragon32_CPython_Linux.png It's runs on my PC with a i4790K CPU with CPyth...

I have refactor the threading stuff. With https://github.com/jedie/DragonPy/commit/119942e50fb3e21aec36f7c54bd89164bb3660e9 i used only Tkinter after() and recalculate the CPU burst count dynamiclly. Seems that's this is a better solution than before and much simpler. The benchmark cycles/sec values...

Yes, because of PyPy has a JIT: http://en.wikipedia.org/wiki/Just-in-time_compilation

Today, DragonPy is runnable with Python 2 and 3... (and pypy2 and pypy3) commits: https://github.com/jedie/DragonPy/compare/fefac43...2and3 And i add a simple benchmark with https://github.com/jedie/DragonPy/commit/c51ee6f3b848fd26d797120c363acd2f6a333905 Usage, e.g.: ...path/to/DragonPy$ python2 Dr...

New Updates to the BASIC editor in DragonPy: To run the BASIC Editor without the Emulator: ...path/to/DragonPy$ DragonPy_CLI.py editor A rudimentary BASIC source code highlighting is available and looks like this: http://www.jensdiemer.de/static/jensdiemer.de/screenshots/20140826_DragonPy_BASIC_Edit...

Now it runs CoCo with Extended Color Basic v1.1 looks like this:


Transfer BASIC listing between editor and Emulator works also with CoCo, now.
