No, I haven't used it in more than 25 years Maybe I will find the magazine one day, and it might have some instructions. Until then, just reading through the listing should give you some hints.

You can transfer values from one register to another with TFR.

I recommend you read the whole Inside the Dragon. It is very well written, and everything you find there is something you eventually would like to know, so it will just save you a lot of time and questions.

btw. exists there a way to display the hex code instead of decimal value ? Can i display the hex code of A or B registers or only from D ? I explained this to you a few pages back :roll: EDIT: Sorry, I explained A/B decimal output, not hex. See the M/L monitor example in Inside the Dragon for such ...

btw. must a assembler be "Dragon" specific or must it only 6809 specific? The assembler is in principle 6809 specific but in the context here we talk about assembler programs running on the Dragon itself, I suppose. Attached is the BASIC program "Editor & Assembler" by A.R.Billingham which I typed ...

Yes, there is a routine to print the value of D. So set B to the number to print and clear A, or if you have to start out with A, clear B and do a EXG A,B.
You can find the routine in Inside the Dragon, or in Graham's ROM reference called Print Number,

Wow, there was plenty more where that came from (google is your friend). I see one of the sites have 660 files for Dragon. However these sites require you to download the files one by one, to register and what not. I would be happy to just download the ~6MB in one go. Did anyone here already downloa...

Can you list exactly the apt package names, needed to use XRoar on a ubuntu/debian system? Those who want to run XRoar on Debian/Ubuntu without building it themselves can use my PPA (personal package archive) at https://launchpad.net/~tormodvolden/+archive/m6809 As of writing, the latest 0.30.1 is ...

Yes, CLOADM it and SAVE it.

Here you have a Dragon DOS binary, instead of the WAV file.

As posted on the CoCo list: Hurray! Drivewire Turbo mode runs at 115200 baud on my Dragon 32! Using my DWDOS-alike stub to load HDB-DOS into RAM, the 8k of HDB-DOS is loaded in a second. DSKINI takes 23 seconds instead of the double. Here is attached the HDB-DOS speed loader WAV file for Dragon 32, ...

$b3c1 LEAX indexed: set $402 to index X |: $b3c1: $a000-$bfff - CoCo - Color BASIC ROM The comment should rather annotate $402 than $b3c1... $b3c1 *** UNKNOWN OP $26[/code] Opcode $26 seems to be a wrong value. Because i didn't find any information about this value. Isn't that BNE? Those opcodes se...
