I wouldn't know.

I see that this is in DOCX format, if anyone wants it in PDF form it is also available on this forum.

P.S. I can still upload the JPEGs if wanted.

How about a real OS with a new GUI? The Dragon already has a "real OS" in the shape of NitrOS-9 , any hardware improvements should therefore be of a form that allows the "Dragon II" to use NitrOS-9 Level 2 and Level 3. Would there be a market for such a machine? Back in the 1980s the C64 and ZX Spe...

I've been using Pere's DragonDOS 1.3a (see http://archive.worldofdragon.org/phpBB3/viewtopic.php?f=8&t=5289#p13272) with XRoar for some years now. Obviously for testing purposes this is not comparable with using real hardware, no motor still running issues for starters, but from my limited tests it ...

For the RF problems it could be that the modulator needs adjusting - no guarantees but it's a possibility. For information on how to test and adjust see my first post in the following thread: http://archive.worldofdragon.org/phpBB3/viewtopic.php?f=8&t=5613&p=15904 P.S. I still don't know what 'cable...

I am not aware of a single command that will explicitly load and execute a cassette based program but some (many?) commercial programs were written and saved in such a way that they autostarted when they were CLOADMed, perhaps it is those programs you are thinking of.

Pere, have you tried checking the AVG log files? It could be that it is preventing the latest XRoar from making certain system calls or is placing XRoar in a sandbox. If so then there should be a way to make AVG ignore XRoar, but not having AVG I can't help much on that matter. If all else fails you...

Pere, I've tried both 32 and 64 bit versions of xroar-snap-2019-49969 on Win 10 and they both work. I did notice, however, that the personal firewall asked for permission for XRoar to access dwmapi.dll and WerFault.exe, perhaps your firewall is blocking this access (since I have never tried other ve...

Hello, and welcome to the forum! Sebiohazard, there are two ways to run machine language programs in DragonDOS. The first, using your example of RACER.BIN, is LOAD"RACER.BIN" EXEC the second, and perhaps more convenient method, is RUN"RACER.BIN" Note that for BASIC programs (those with a .BAS extens...
