## Build Instructions
|
||||
|
||||
On Unix-like systems (including Mac OS X) `make all` should build
|
||||
the desk accessory files into `out/`
|
||||
the desk accessory files (original and new) into `out/`
|
||||
output with a `.built` suffix.
|
||||
|
||||
The `.built` and `.bin` files can be compared
|
||||
For the original DAs, the `.built` and `.bin` files can be compared
|
||||
using `diff` to ensure that no changes have been introduced by the
|
||||
disassembly process.

Show Image File
|
||||
---------------
|
||||
In Apple II Desktop, select an image file. Unfortunately, these are
|
||||
hard to identify in A2D; they appear as a binary file (icon is <01>)
|
||||
and are usually either 17 (single hi-res) or 33 (double hi-res) blocks
|
||||
- you can check View > By Name or use Special > Get Info... to see the
|
||||
size.
|
||||
|
||||
Then select Show Image File from the Apple menu. The image should
|
||||
appear. If garbage appears, it was probably not an image file. You can
|
||||
move the mouse pointer while the image is displayed. Click the mouse
|
||||
button or press Escape to return to the DeskTop.
|
||||
|
||||
|
||||
This Apple
|
||||
----------
|
||||
Select this item from the Apple menu to see an overview of the model
|
||||
of computer, the CPU, an estimate of RamWorks memory expansion (if
|
||||
present), and what cards can be identified in each slot.
|
||||
|
||||
|
||||
Eyes
|
||||
----
|
||||
Select this for a demo showing two eyes that follow the mouse cursor.
|
||||
The window can be moved and resized.
