keymap file: use 1 line per keycode to translate, with the following pattern: <SDL_host_keycode> : <SDL_oric_keycode> Here is the file I use on my french laptop (decimal values): 38 : 49 233 : 50 34 : 51 39 : 52 40 : 53 45 : 54 232 : 55 95 : 56 231 : 57 224 : 48 41 : 45 61 : 61 33 : 92 94 : 91 36 : ...

Nice demo and port! A small note, the BRxx instructions of the original version used a relative displacement which allowed to load a sweet16 program anywhere in memory, but this version seems to use absolute addresses. Maybe a relative displacement of +/- 32767 might be enough (but this will slightl...

FTDOS use always IRQ to read or write data

actually, follow-up query on the Jasmin: if you can select arbitrarily many then how do you deselect drives?

Drive 0 -> 0x3FC, Drive 1->0x3FD, Drive 2->0x3FE, Drive 3->0x3FF
To select a drive write 1 to the corresponding address and 0 to deselect.

I do not remember ever having encountered this problem with my Jasmin.
Do you have the same problem within other address ranges?

Works with Oricutron too

<r>I think the FDC should be a WD1793, not a MB8877.<br/> They are "firmware compatible" but not "pin compatible"<br/> <br/> Here is the datasheet: <URL url="http://bitsavers.org/components/westernDigital/FD179X-02_Data_Sheet_May1980.pdf"><s>[url]</s><LINK_TEXT text="http://bitsavers.org/components/...

I just made a PR on Github with the patch to add the support of the WRITE TRACK command.

I found my quick and dirty patch, it works with Ftdos and Sedoric.

I still have to add some checks to avoid having buffer overflow (when trying to format an image with more tracks than the image file)
Also the header of the disk image isn't modified...

I wrote a patch some time ago to support the WRITE TRACK command but I have never published.
I needed it for a program that formatted its data diskettes (can't remember its name)

If I remember correctly, my modification works but the delay before the IRQ interrupt may not be accurate.

There is something really weird, the home page says I'm the only registered visitor with more than 200 guests If I go to a random discussion, I'm with at least 10 guests (even in a post from 2006!) and the response time is very high. Can you check the log files of Apache and see if some IP addresses...

The default start address for the .text segment is $1000.
So, the program is assembled at $1000, and BNE $9730 is out of range.

You must set the start address with the -bt option: xa isscat.txt -o isscat.s -e errorlog.txt -bt 38656

Note: 38656 = $9700

@chema, @iss: regarding the issue with The Quill, I think i found a way. After loading quill.tap: disable the option "Turbo Tape" in the hardware menu select "Save tape output" and set a file name go back to the quill and save your datas (you can save many times) go to Oricutron menu and select "Sto...

The fix was accepted and merged in the repository yesterday.
