Re: Track reading (Sedoric / FDC)
The disk geometry/structure is something totally arbitrary: On the Oric as well as on the Atari ST or PC, you could have mixes of number of sectors, sector size, track density on the same floppy: You can totally have a MSDOS compatible boot sector (512 bytes per sector) that loads something that wil...

Re: Track reading (Sedoric / FDC)
The code I used in FloppyBuilder to generate the floppy is based on what Fabrice did in his tools, so technically they are compatible at the structure level. See http://miniserve.defence-force.org/svn/public/pc/tools/osdk/main/FloppyBuilder/Floppy.cpp for more details. Regarding the Pravetz and Appl...

Re: OASIS very very early alpha tech demo
Oh, and I will need a nice font. For now I am using the one in Space:1999, but I'd prefer a 8x6 nice font, such as the ones Dbug usually design :) Which style of fonts were you thinking of, and which characters do you need? If you are in Hires, you can display more then just the standard 96 charact...

Re: OSDK article: C/Assembler code sharing
There are none at the moment.
I'm doing some work on the FloppyBuilder/loader, and these will be the first to benefit from that system: I will simplify the Loader API so it feels more natural to use using the method I was presenting in the article.

OSDK article: C/Assembler code sharing
I took a bit of time to write about how to use the preprocessor to share file between C and Assembler modules:

Re: Oricutron 1.0 (EDIT: Now 1.2)
I'm going to be very pragmatic on that one: I guess the only persons who really should decide ultimately are the ones that have regularly committed to the current codebase of Oricutron
After all, they are the ones who are going to live with the choice.

Re: Oricutron 1.0 (EDIT: Now 1.2)
Google code is turning read only on the 25th of August. So what do we do ? Move to github ? Ask Dbug to add us to his SVN ? I don't have any problem with adding it to SVN, but that would probably be detrimental to the code quality as there is no support for bug tracking or stuff like that. For a la...

FloppyBuilder sample program
I added to the SVN depot a minimalist example of how the FloppyBuilder works: http://miniserve.defence-force.org/svn/public/pc/tools/osdk/main/Osdk/_final_/sample/floppybuilder/ It's not 100% finished, there are still some commented out stuff here and there, and it does not show the entire set of fe...

Re: Oric SD Drive in production
Having IRQ enabled during read operations will be real problem. In my opinion it's impossible. Users with 8D FDC hardware have to live with no music during disk I/O, but they can enjoy the heavy metal noise from the FDD. Like this one :). Ok, in regard to the read speed, how does the whole system d...

Re: Oric SD Drive in production
For FloppyBuilder based software I guess all we need is read sector, and eventually a write sector for save games.
What scares me a bit is the "exact timing"; can we still have IRQs between sector reads so demos could continue play music while loading?

Re: Oric SD Drive in production
Else, as Dbug mentioned DOS-8D uses RWTS exactly as Apple DOS 3.3 do. I already disassembled DOS 2.10 and extracted the RWTS. The source can be reused in any project (i.e. it's movable and not bound to any fixed address). The surprise is that the RWTS is bit-for-bit equal with the RWTS from Apple D...

Re: Oric SD Drive in production
Ok, as far as I saw, the Apple format is relatively simple, 35 tracks of 16 sectors, and the boot sectors in the first sector of the first track. The Apple system uses a RWST (Read/Write Sector/Track) set of routines which are on the disk controller board which contains all the code to access the dr...

Re: Oric SD Drive in production
DBug: the way the floppy is written is quite different from the standard floppy using on most computer and the CAV floppy used by Apple on the ][ and earlier 400/800K Macintosh Floppies. I don't think it would be possible to do an universal floppy image that would work for Microdisc/Jasmin and this...
