IMHO neally all bugs should be catched in the CPU... I add some tests with the monitor ROM from sbc09... And i add a console script (witch not used socket interprocess communication) for fast tests. Just run: ...path/to/DragonPy$ python2 console_6809_test.py or use PyPy: ...path/to/DragonPy$ pypy co...

Oh, i now see: http://sourceforge.net/p/toolshed/code/ ... equivs.asm
That's interesting

http://neil.franklin.ch/Articles/200704 ... reter.html is really interesting to read, IMHO


btw. is there a other (english) book with a ROM Listing?

I found (maybe the last) but in my Emulator: The DAA Instruction has set wrong CC Flags: https://github.com/jedie/DragonPy/commit/341312d7570bb0e5e30265436a063955164d7a46 I found this by adding unittests with the sbc09 ROM. That's because the BASIC Interpreter doesn't use DAA :P But it don't know it...

I have a idea for a BASIC editor on PC (Windows/Linux/MacOX) to help writing longer BASIC programs. I would also like to bind it to DragonPy and/or XRoar to easy run changes BASIC code with the emulator. Easier as use XRoar "File/Run" menu entry. The Idea it to copy the listing directly into Emulate...

The interesting thing is, that the BASIC is very similar to the Dragon one.

Maybe we can compare and adopt some same lines

Does anyone know how RND() and the TIMER work on the Dragon? How are they generated?

I have found this bug and get the same output in DragonPy, now. Commit: https://github.com/jedie/DragonPy/commi ... 4fac528353

Thanks! I bugfix it with: https://github.com/jedie/DragonPy/commi ... c71a73edf5

Think i have it from 6809js, see: https://github.com/maly/6809js/commit/e ... nt-6987200
