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...

Hi, after modifying the dweeb VDIR so that it is able to work with big disks and with highly fragmented files, I have given a peek to the DLOAD and the more recent DLOAD1 dweebs. They have a similar problem that shows up when the file occupies more than 11 extents. I have corrected them and I am att...

Hello, once verified with a lot of disks, it seems it works OK. So, I have decided to clean it up a little, then I had tested again and as it works flawlessly too, I send this new version. I am going to delete the last version to avoid errors downloading ... This is the final version of this dweeb, ...

well, finally the F (full) version works without problems. Using the big disk has shown that when the first LSN for a file is more than 999 (4 digits), the text shifts to the right every line it happens ... I attach: - the corrected dweeb VDIR (same name, but different one) - the source code (for as...

Hi Stew,

thanks, I had not made this test.
The JSR [DWRVEC, PCR] works well and in fact with the same bytes, not sure about the cycles, but I just don't matter.

cheers
