Executor is a Macintosh emulator for PCs developed and distributed by ARDI. Information and free demos (the demo runs for 10 minutes at a time) are available from the ARDI home page, http://www.ardi.com.
To get the desired results it is important that you not skip any of the steps outlined below, including reading the documentation!
1 -- READ EXECUTOR INSTALLATION INSTRUCTIONS
2 -- READ EXECUTOR FAQs
3 -- INSTALL EXECUTOR
5 -- ALLOCATE SUFFICIENT SPACE
Before running Executor it is a good idea to make sufficient space to run Executor and the SEES exercises. Executor uses specially formatted Hierarchical File Volume (HFV) files to simulate Macintosh hard drives. You may want to create an HFV file for SEE Image and the images. To do this in Windows, double click on the file name "makehfv.exe," which is in the directory where you installed Executor (i.e., C:\Executor). Follow the instructions to add an HFV file about 25 MB or larger.
This will create a file called seeimage.hfv in the Executor directory, which is 25 MB in size, and it will appear in Executor with the name SEE. More HFV files can be created later if the first one is insufficient.
6 -- VERIFY EXECUTOR PREFERENCE PANEL SETTINGS
Start Executor. To access the Preferences Panel, type Alt-Shift-5 and make sure 7.0 is in the System box and 256 is selected for Number of Colors. If the 256 colors option is not available it may be necessary to run the program "SciTech Display Doctor" supplied on the Executor CD to emulate VESA 2.0. Click Save if you made any changes then click OK. If you don't click Save, any changes you made will be lost the next time you run Executor.
To open the SEE folder you created above, click on the file cabinet icon in the upper left portion of the Executor window. You should see the SEE folder listed with the other folders (Windows disk drive letters). Double click on the SEE folder icon.
7 -- DOWNLOAD SEE IMAGE 68K FROM THE COMPUTER LAB SOFTWARE PAGE
It is compressed and coded with Macintosh software so you will see the file SEEImage.sea.hqx or SEEIma~1.hqx wherever you specified it to be saved. You will decompress and decode this file in Step 9.
8 -- COPY THE SEE IMAGE FILE TO THE SEE FOLDER
Click on the folder (Windows drive letter) at the top of the Executor window where you have the SEE Image file. Open all of the necessary directories until you find the SEE Image file and then drag that file onto the SEE folder.
9 -- EXPAND THE SEE IMAGE FILE SO IT CREATES THE SEE IMAGE FOLDER
Click on the Applications button at the top of the Executor window (just to the right of the file cabinet icon -- it looks like a pen in an inkwell). This will list the available applications across the top of the Executor window. Double click Stuffit Expander. Next, click on File/Expand and then click on the Drive button until you see "SEE" listed at the top of the file window. You should see the SEE Image file listed in the window. Double click on SEEImage.sea.hqx and the file should be decoded and expanded. To verify that this worked, close Stuffit Expander and see if there is a new folder named SEE Image in the SEE folder. If it is there, you should be all set to follow the instructions in the tutorial and exercises.
NOTE: If Executor displays an error message when you start SEE Image that not enough memory is available to run SEE Image you'll need to allocate more memory. To do this you need to use a command line switch that forces Executor to have a specified amount of memory available. You can do this by using the following command to start Executor:
executor -applzone 11000
Another way is to create a shortcut to executor.exe. To use command line switches with a shortcut, you need to create a shortcut to executor.exe (right click on executor.exe in Windows and then select Create Shortcut), then select it and choose Properties... using your right mouse button. The Properties panel has several tabs, one of which is labeled Shortcut. After selecting the Shortcut tab, you can then edit the "Target:" field. Keep the information that is already in there (e.g., C:\Executor\executor.exe) and then add a space, followed by the command line option(s) you want to use when you double click on that shortcut (e.g., -applzone 11m).
You can also create a file called commands.txt in the same directory that includes executor.exe. In that file you would put -applzone 11m.
When you're ready to download and unpack data files, do it in the same manner as described above in steps 7 through 9.
