This is an Apple II double high resolution graphics package. The distribution floppy includes

• DHRLIB - DHGR library with Applesoft ampersand interface
• MAPLIB - version of DHRLIB with only what is needed for maps
• TILE - program to build tile sets, e.g., for fonts or scrolling maps
• MAP - program to build uncompressed maps
• PAINT - program to create and encode artwork
• REPAINT - program to modify artwork
• FONT1 - DHGR font used by programs

To try the ampersand library in immediate mode, just boot the floppy, which can be found on the release page. You should get the FP prompt. Try this:

&dhr
&hcolor = 11
&trap at 10,50,10 to 20,30,50
&hcolor = 1,1,2,2
&stroke #7 at 500,100
&print "Hello World!" at 1,1

If the text looks bad, you may want to read this.

If you want to install SDP II on a ProDOS hard drive:

• Boot the floppy
• Type -HD.INSTALL when you see the FP prompt.
• Follow the prompts to select the install location.

This should also work on other kinds of ProDOS volumes (e.g. MicroDrive).

There is no main menu, you just run things from the FP prompt.

• -CONFIG sets up default paths and tiles
• -PAINT and -REPAINT work with pictures
• -TILE creates tile sets (or fonts)
• -MAP creates maps (create a tile set first)
