Hi Ken, I have the file "nos9v303_d64COHR_becker.dsk" mounted as Disk0 in DriveWire Then I start XRoar without DDOS or with DDOS11C When I enter DLOAD"DOS" The screen shows the message "NITROS9 BOOT" But nothing happens on the screen, it simply hangs the computer. But ... if I do that with HDB-DOS i...

Hi Ken, pleased to hear from you again! I have downloaded all that info, I'm thinking of getting into that old project again. I will try to alternate it with The Hobbit conversion, where I have about 40% of work done. But there is still quite a lot of code to convert and test! cheers have a nice wee...

Back again, Jon I have started my Dragon (without drives) but connected to the PC via DriveWire. With drivewire having in slot0 the NitrOS-9 disk for DW, I pressed Shift to avoid autorun... Then DLOAD"DOS" has started NitrOS-9 without problems So I think there is some sort of uncompatibility with XR...

Hi Jon, I attach here the .bat file I use ... it's a bit special because I have all inside folders, but you will get the idea! cheers pere screen.jpg EDIT: All the tests I have made using any DOS different from HDB-DOS have failed (maybe I am doing something wrong, I don't know) It seems to me that ...

Hi Jon, I don't know much about OS-9/NitrOS-9, but what I have done is: In XRoar I have a bat file that loads a Dragon64 with HDB-DOS Before starting it, I start DriveWire putting a special NitrOS-9 disk in slot 0 Then I start the bat file and get the normal Dragon prompt Then I use: DLOAD"DOS this ...

Hello, Jon, have you got the DosPlus4.9 source code or a commented unassembled file? Is there a user/programmer manual for this DOS? I would like to compare it to the SuperDOS and DDOS12A to choose the one that could make things easier to convert it to something like the HDB-DOS thanks in advance ch...

Hi Jon, There are a few assembler source files but neither as commented as the unravelled CoCo series. I am attaching here what I have found in my PC folders, not sure if they are the very last version, but they do help a bit. I hope the file names are self descriptive If anybody had a better source...

Hi Jon, thanks for this explanations ... this is really very, very interesting! I had begun some time ago by using map1 (all RAM) where I copied the Basic and the Dragon Data DOS v1.1c There I intercepted these two routines: ReadAbsoluteSector and WriteAbsoluteSector, I had some code there and when ...

hello Jon, thanks, I would like to be able to work with my Dragon and its double drive but with Drivewire at the same time And I would be happy if every DOS command could be applied to both worlds, real and virtual If I only had the time, I would attempt to convert the DOS commands to work with driv...

Hello, Just a comment about the last modified dweebs. I have kept both versions: - VLOAD that uses TABLDR to do the final part of the task - VLOAD1 that is a standalone dweeb The very first one was developped to 'practice' on how to call DWLOAD from inside a ML program in order to load and execute a...
