I just got a brand new Dragon 64 by Tano and now I'm on dragon scene It's just so beautiful!
Some of you guys knows my superide package and tools. I am an active coco developer.
Right now I need to find a way to transter disks to the dragon as I don't have an old pc (and I don't want to have one!). I've contacted lafuentes for the FDC.
I don't want to turn my dragon into a coco as I have a stack of cocos in my basement but only one dragon
I'm thinking maybe I can do it using a rawcopy on os-9 using my cocos and the superIDE. I copy the VDK image without the header and make a raw copy sector by sectors only writing the LSN0 at the very end. That should work right ?
Ultimately I could do a tape to dsk tool but that will give so much work on PC and Dragon.
For your disk questions I don't think I can help much. What is it that you want to transfer from and to? From disk images on a PC? To a standard(?) 3.5" floppy drive through the Lafumat FDC?
In theory anything that can do a raw write of the VDK image (with the header removed) should work - You can read/write dragon disks using DD in Linux providing you configure the FDC correctly to deal with 40 tracks and the correct sector sizes etc.
Or- modify SuperIDE to load and work with the Dragon (probably not too hard)
I made a rawcopy tool in OS-9 copied the entire 40-tracks vdk without the header into my superide os-9 image and performed the sector by sector copy (copying the first sector at last, because after that os-9 goes crazy on bad disk geometry). Seems to be all copied there, but I still don't have the dragon fdc.
Yes, ultimately i would like to patch superDOS to read from superIDE disk images, but for that i would need a disassembled superdos. It would be easier starting from that . My ideia is to replace floppy code for superide access.
I think you and PRIME need to talk - I suspect he can help you here having built an SD card interface for the Dragon - It also works with tape images (CAS files) allowing direct loading of .CAS files as if they were loaded via tape (but at full speed!).
I attach his disassembled and commented DragonDOS 1.0 source which can be compiled for Dragon 32/64 and Dragon Alpha use - it may prove useful

By the way, I ported HDBDOS to the Dragon and made it run from RAM on a Dragon 32 some weeks ago. HDBDOS has support for the SuperIDE. I had intended to test it out on hardware (DriveWire) and merge it cleanly into Toolshed before announcing it, but if anyone wants to test it before I get to that I can share it as it is.
