Files

• TARGETS - lists DAs (used by makefile and other scripts)
• Makefile - cleans/builds targets
• *.s - source (originally generated using da65, now modified)

Build Instructions

On Unix-like systems (including Mac OS X) make all should build the desk accessory files (original and new) into out/ output with a .built suffix.

Getting The DAs Onto Your Apple II

There are a handful of approaches for getting the files on your real or virtual Apple.

Create a Disk Image

To produce a ProDOS disk image with the DA files, install and build the Cadius tool:

git clone https://github.com/mach-kernel/cadius /tmp/cadius
make -C /tmp/cadius
CADIUS=/tmp/cadius/bin/release/cadius

Then from the desk.acc/ directory, run: res/package.sh

This will generate: desk.acc/out/DeskAccessories.po

Mount this disk image in your emulator, or transfer it to a real floppy with ADTPro, then follow the install instructions below.

Mount Folder in Virtual ][

If you use Virtual ][ as your emulator, you can skip creating a disk image.

At the top level of the repo, run res/go.sh to build all targets, then run res/mount.sh. This will create a mount/ folder and the built files will automatically be copied in. Then run Virtual ][ and use the Media > Mount Folder as ProDOS Disk... menu item, then select the mount/ folder. A new ProDOS volume called /MOUNT will be available. (Tip: use the Special > Check Drives command in A2D to make it appear.)

(The res/go.sh script will helpfully run res/mount.sh automatically if the mount/ folder already exists.)

Other

If you need to copy the files some other way (e.g. via CiderPress), you need to do the following:

Transfer the .built files in the out directory, ensuring you:

• Drop the .built suffix
• Ensure they have ProDOS file type $F1
• Ensure they have start address $0800
• Ensure they have auxtype $0640 (to match the originals)

The last three are tricky, and depend on how you're copying the files.

Install Instructions

Once you have the files accessible on your Apple:

• Copy the files into your A2.DESKTOP/DESK.ACC folder (using A2D or any other tool)
• Restart so A2D picks up the new DA

Tips:

• You can use the Sort Directory DA to order the files, which controls the menu order:
  • Open the A2.DESKTOP/DESK.ACC folder
  • Hold Open-Apple and click on each file in the desired order
  • Select Sort Directory from the Apple menu, and verify the order
  • Restart
