robcfg scanned a Delta manual and posted here: http://archive.worldofdragon.org/phpBB3/viewtopic.php?t=657 Though it doesn't quite seem to match up exactly with the behaviour of the ROM dump we have. Cheers, I hadn't spotted that, the couple of commands that I have tried cirtainly seem to be accept...

Thanks for that much appreciated, now if someone could scan the Delta dos cart we'd have the instructions for all the Dragon disk controllers.

Cheers.

The source for HDB-DOS is now part of the toolshed mercurial repository. http://toolshed.hg.sourceforge.net/hgweb/toolshed/toolshed/file/33cf1caaeb27/hdbdos/hdbdos.asm Ahh excellent,I knew it had permission to be distributed now, didn't realise it had been open sourced, might take a look at that th...

Wow, great accomplishment! Can't wait to see the details and give it a try. Bringing the Drivewire platform to the Dragon opens so many possibilities - flexible storage, virtual printing , MIDI and even telnet. Phill, since you have previously ported SuperDos to the CoCo, do you think you can do th...

Right after some initial testing, I created a drivewire disk saved a file and loaded it back. It seems that the Dragon 64 (and probably the 32 as well), will work at 56K as the CoCo2. Next step is I guess to try and boot the DriveWire version CoCo NOS9 on the 64 and see if that works. The circuit is...

Great news! How fast can the Dragon run the bitbanger port? Is there any reason why it won't reach 57.6K like the Coco2? Currently I see no reason why it shouldn't but have not yet built the level / polarity converter yet so don't know for certain. Is there any easy way of testing it ? I suppose I ...

Nice! Does the pal timing have any effect on the programs when in CoCo mode? I've not done any extensive testing, it shouldn't affect raw CPU speed as that runs at the same clock speed, determined by the SAM, I guess it would only affect programs that synced to the frame sync. But i guess that woul...

Cop[y of what I just posted to the CoCo mailing list as it may also be of interest here. Hi all, I've just managed to modify a Dragon 64 to be dual personality, both as a Dragon 64 or a CoCo. This involves two circuits, one is a 27256 (or bigger) that replaces IC18, and has the normal Dragon rom in ...

Might be worth checking out the CoCo Toolshed development tools, http://sourceforge.net/projects/toolshed/ this includes an assembler and tools to read and write OS9 and Tandy CoCo disks.

It's what I use for Dragon/CoCo development, under both Windows and Linux.

Cheers.

Hello Phill, It's really great your project! With this you will give the possibility to feed our Dragons to a lot of users that don't have flopppy drives. If possible, I will like one when available Thanks :) I really must get back to working on DragonMMC, I made some pre-production boards which a ...
