You mean http://fritzing.org/ ?

With https://github.com/jedie/DragonPy/commi ... e246b934a7 i hope to fixed the indexed addressing modes.
I have now looked into "Programming the 6809" and here: http://www.maddes.net/m6809pm/sections.htm#sec2_2_5_1

Opcode 0x26 seems to exist Implemented with https://github.com/jedie/DragonPy/commit/60b1728ac91794919a97589babcb8672c14cc846#L0R902 I started to adoped the complete branch_cond() stuff from: https://github.com/jedie/XRoar/blob/master/hd6309.c#L546-L570 but it seems that there is some mismatched wi...

I have made a sourcecode mirror in github here: https://github.com/jedie/XRoar/

I have made this only for easier linking code parts and nice browsing.

From a quick look at your cpu6809.py it seems that you have only implemented a few opcodes. How do you think it can work if you don't fill them in? Yes, i implement the lastes "unknown" opcode... step-by-step... Maybe later i can merge some of the code... The CPU looks at the reset vector at $fffe ...

I implement more ops and the Indexed addressing modes: https://github.com/jedie/DragonPy/blob/fbbaeaee14ce2c3dd1754710bab9b80386c68e01/cpu6809.py#L672 think there must be exist a few bugs :( Current output: init 16384 Bytes ROM (0x8000 - 0xc000) Read 16383Bytes from d32.rom into ROM 0x8000-0xbfff in...

The floppy drive is emulated, not the controller. Yes, but this is also a nice way: Use a controller clone (like the one from lafumat) and emulate the floppy with Raspberry Pi to share the files directly into the local LAN ;) OK, emulate floppy controler + floppy drive would be nicer... And maybe t...

It seems that it is possible, read: http://www.raspberrypi.org/phpBB3/viewt ... 41&t=34143

Have now done this: ./6809dasm.pl org=0x8000 forceorg=0x8000 end=0xbfff d32.rom >d32.rom.asm Then i add comments into d32.rom.asm by a Python script ( https://gist.github.com/jedie/6573808 ) and use the information from http://archive.worldofdragon.org/phpBB3/viewtopic.php?f=8&t=4365 result is here:...
