** 27.12.2018 changes by byrtolet:
Oric atmos with read-only dos8d support.

keyboard:
Scroll Lock - toggles vga/rgb+composite
End - NMI
Home+End - reset
Page up - image number up
Page down - image number down

While holding the Home key, some hexedecimal numbers apear.
First two are the curent floppy track.
Next two are the current image number;
The reset four is the current program counter register. The value is latched when the Page Down key is pressed.

The images sould be prepared with dsk2nib utility
and should be 232960 bytes long each.

then they sould be written to the sdcard starting on sector 0

One could use on linux the command
cat *.nib >/dev/sdf

which will put all images with the .nib extension in the current
folder on the sdcard located on device /dev/sdf (please double check
the used device)
