Re: Utility for converting a binary file to a .CAS file

The difference between DragonDos and DECB binaries is in the preamble/postamble (which are similar to the namefile block in CAS files) DragonDos binary files have a 9 byte header of the following format: Offset Value 0x00 0x55 0x01 Filetype 0x02:0x03 Load Address 0x04:0x05 Length 0x06:0x07 Exec Addr...

Re: Utility for converting a binary file to a .CAS file

Yep, sure. I have sort of a hack, on a utility I have to check the block's crcs, that extracts the binary files to disk. So I can clean a bit and add it to the program. I think that, most probably, I'll have it before the end of the week or earlier next week. Quite busy lately... :D Great, thanks. ...

Re: Utility for converting a binary file to a .CAS file

Is there a utility to convert the other way around: CAS to BIN?
I couldn't find any.
Rob, this could be a useful addition :D

Re: NitrOS-9 v030209

Hi Pere, These disks are based on my own compilation of the NitrOS9 Mercurial source done about a year ago. Unfortunately, the current NitrOS9 source for the Dragon seems to create disks that aren't bootable (at least with my configuration). My complete working NitrOS9 disk set (CoCo & Dragon, 30 me...

Re: NitrOS-9 v030209

Here is NitrOS9 v030209 for the Dragon 64 in VDK format (works on XRoar). There are 2 versions attached, one boots in VGD 32 column mode and the other in 51 columns mode. Note that the NitrOS9 51 column mode is not compatible with Dragon Data's go51 mode, therefore Dragon Data's Stylograph and Dynac...

Re: Floating pin 12 on LM1889 colour modulator

On my Tano Dragon (Issue 2) the LM1889 is soldered. All pins seem to be in place.
On my Dragon 32 (Mark II Issue 5) the LM1889 is socketed, but none of the pins is bent.
