+
+	unsigned char * InitNCR(volatile void * BoardAdress, struct MonDef * md = &MON_640_512_60);
+
+   This routine initialises the Retina hardware, opens a
+   text- or gfx-mode screen, depending on the the value of MonDef.DEP,
+   and sets the cursor to position 0. 
+   It takes as arguments a pointer to the hardware-base
+   address as it is denoted in the DevConf structure
+   of the AmigaDOS, and a pointer to a struct MonDef
+   which describes the screen-mode parameters.
+   
+   The routine returns 0 if it was unable to open the screen,
+   or an unsigned char * to the display/attribute memory
+   when it succeeded. The organisation of the display memory
+   is a little strange in text-mode (Intel-typically...) :
+   
+   Byte  00    01    02    03    04     05    06   etc.
+       Char0  Attr0  --    --   Char1 Attr1   --   etc.
+       
+   You may set a character and its associated attribute byte
+   with a single word-access, or you may perform to byte writes
+   for the char and attribute. Each 2. word has no meaning,
+   and writes to theese locations are ignored.
+   
+   The attribute byte for each character has the following
+   structure:
+   
+   Bit  7     6     5     4     3     2     1     0
+      BLINK BACK2 BACK1 BACK0 FORE3 FORE2 FORE1 FORE0
+      
+   Were FORE is the foreground-color index (0-15) and
+   BACK is the background color index (0-7). BLINK 
+   enables blinking for the associated character.
+   The higher 8 colors in the standard palette are
+   lighter than the lower 8, so you may see FORE3 as
+   an intensity bit. If FORE == 1 or FORE == 9 and
+   BACK == 0 the character is underlined. Since I don't
+   think this looks good, it will probably change in a
+   future release.
+
+   There's no routine "SetChar" or "SetAttr" provided,
+   because I think it's so trivial... a function call
+   would be pure overhead. As an example, a routine
+   to set the char code and attribute at position x,y:
+   (assumed the value returned by InitNCR was stored
+    into "DispMem", the actual MonDef struct * is hold
+    in "MDef")
+   
+   void SetChar(unsigned char chr, unsigned char attr,
+                unsigned short x, unsigned short y) {
+      
+      unsigned struct MonDef * md = MDef;
+      unsigned char * c = DispMem + x*4 + y*md->TX*4;
+      
+      *c++ = chr;
+      *c   = attr;
+      
+   }
+   
+   In Gfx-mode, the memory organisation is rather simple,
+   1 byte per pixel in 256-color mode, one pixel after
+   each other, line by line.
+   
+   Currently, InitNCR() disables the Retina VBLANK IRQ,
+   but beware: When running the Retina WB-Emu under
+   AmigaDOS, the VBLANK IRQ is ENABLED.
+   
+	void SetCursorPos(unsigned short pos);
+
+   This routine sets the hardware-cursor position 
+   to the screen location pos. pos can be calculated
+   as (x + y * md->TY).
+   Text-mode only!
+
+	void ScreenUp(void);
+
+   A somewhat optimized routine that scrolls the whole
+   screen up one row. A good idea to compile this piece
+   of code with optimization enabled.
+   Text-mode only!
+
+	void ScreenDown(void);
+
+   A somewhat optimized routine that scrolls the whole
+   screen down one row. A good idea to compile this piece
+   of code with optimization enabled.
+   Text-mode only!
+
+	unsigned char * SetSegmentPtr(unsigned long adress);
+
+   Sets the beginning of the 64k-memory segment to the
+   adress specified by the unsigned long. If adress MOD 64
+   is != 0, the return value will point to the segments
+   start in the Amiga adress space + (adress MOD 64).
+   Don't use more than (65536-64) bytes in the segment
+   you set if you aren't sure that (adress MOD 64) == 0.
+   See retina.doc from MS for further information.
+
+	void ClearScreen(unsigned char color);
+
+   Fills the whole screen with "color" - 256-color mode only!
+
+	void LoadPalette(unsigned char * pal, unsigned char firstcol, 
+	                 unsigned char colors);
+
+   Loads the palette-registers. "pal" points to an array of unsigned char 
+   triplets, for the red, green and blue component. "firstcol" determines the 
+   number of the first palette-register to load (256 available). "colors" 
+   is the number of colors you want to put in the palette registers.
+
+	void SetPalette(unsigned char colornum, unsigned char red, 
+	                unsigned char green, unsigned char blue);
+
+   Allows you to set a single color in the palette, "colornum" is the number 
+   of the palette entry (256 available), "red", "green" and "blue" are the 
+   three components.
+
+	void SetPanning(unsigned short xoff, unsigned short yoff);
+
+   Moves the logical coordinate (xoff, yoff) to the upper left corner
+   of your screen. Of course, you shouldn't specify excess values that would
+   show garbage in the lower right area of your screen... SetPanning()
+   does NOT check for boundaries.
