Re: CoCoVGA upgrade

Moving forward slowly and finally got the time this evening to mount the CoCoVGA button board on system. I didn't want to have the port on the dragon case top so aligned the drilling template against the top lower edge and against the power supply port which worked out fine. Hello, Is there any cha...

Re: Coco 3

Hello, most of the users of this group have migrated to the Facebook Dragon group, just a few are still here :-( Maybe some are in the TRS-80 Color Computer group too. You will find at the end of this message a link to that Facebook group for maybe you'd want to give it a peek cheers and good luck! ...

Re: MAME Emulation

Hey Robert,
got it working!!
I just had to create a copy of the dragon64.zip file and rename it to dragon64h.zip
Now I can look at the code with lots of 6309 opcodes well disassembled
Thanks a lot!

Re: MAME Emulation

How do you tell MAME that it should accept the 6309 opcodes?
Inside the dragon64.zip there are only three ROMs, two for Basic and one for DOS
But I see no place to state the fact that you would code for the 6309 CPU

cheers

Hello Robert,
I am using the one I have been using for the std Dragon, so I have to asume it uses a 6809
Is there a different version that accepts a 6309 CPU?
I would appreciate if you could upload it here to test it!
thanks a lot

Re: How to use GDB-Xroar to debug 6309 code

Hi Ciaran, thanks for answering that fast! I was afraid that this could be the answer. I am so comfortable using both XRoar-GDB that I would have liked it for 6309 debugging too :-( It seems that I will need to use the MAME/MESS emulator if that one is able to understand 6309 coded programs ... chee...
