_______________________________________________________________

1) Requirements

To use FUSION, you need:

	* Apple 512K or 1MB ROM image from a 680x0 based Macintosh.
	* Macintosh System 7.1 or newer System Software.
	* A '486 or newer CPU.
	* At least 8 megabytes of memory (RAM).
	* At least 20 megabytes of hard drive space.
	* MS-DOS v3.2 or newer.
	* VESA v1.2 or newer (v2.0 for "Direct" driver).
	* MS-DOS based mouse driver.

To use the audio support, you will need:

	* MS-DOS based audio driver(s) that implements the
	  Sound Blaster or Windows Sound System.

To use SCSI devices, you will need:

	* MS-DOS based ASPI driver(s).
	* Third-party Mac SCSI driver software or CD driver
	  software (for CD drives that are not compatible
	  with AppleCD).

To use the emulated CD support, you will need:

	* MSCDEX, properly installed for your CD drive.

If you order the Mac OS, make sure your retailer knows that
you want "Generic" System software; that is, you want Mac OS
that can be installed on any Macintosh.  This is the only kind
that will work with FUSION.

Do NOT use System software that comes with a particular Mac.
It will NOT work.

Do NOT use pre-made HardFiles from other Macintosh emulations,
(except from the Amiga version of FUSION)...  they will NOT work.
These HardFiles (sometimes called, "filedisks" or "bootfiles")
may appear to function to a degree, however, you will experience
problems using them.  Please do not ask for technical assistance
if you are using one of these files.. you will be wasting our
time and yours!

99.9% of all problems encountered with FUSION are due to improper
or improperly installed system software.  It is essential that
you read the section of this documentation concerning system
software installation.

Mac OS 8 and newer requires a 1MB ROM image.  Mac OS 7.6 and
later will work with 512K or 1MB ROM images.

2) Setup Program (SETUP.EXE)

Layout:
------
The setup program consists of GADGETS (text that is in a box
having a black background is considered to be a "gadget"),
and settings window.  The settings window contains the
information and controls that pertain to the selected gadget.
(e.g.:  when MEMORY is selected, you can choose how much memory
to give to the emulation).

Note that if you do not get a mouse pointer of some kind, you
will need to install a DOS mouse driver (see above).  The mouse
is not necessary for the setup program, but you will need it to
properly emulate the Mac.


Quitting:
--------
To quit the setup program, click in the upper left corner of
the screen, or press Alt-X.


Mouse Control:
-------------
Clicking on any gadget will have some sort of an affect on the
settings.


Keyboard Control:
----------------
The setup program was designed to be used completely from
the keyboard if necessary.

Pressing CTRL-Up/Down keys will scroll through the list of
gadgets.

Pressing the TAB key will scroll through sub-options.
Pressing the cursor right/left keys will change the
parameters for that sub-option.  Pressing the cursor
up/down keys will scroll through entries.  Pressing the
space bar in an entry will toggle the entry (e.g.: Y/N).

Pressing the RETURN key in any sub-window will cause an action
based on the gadget (EXIT will return the previous menu).

Pressing the ESC key in any sub-window will exit to the
previous menu.


File Requester (mouse control):
------------------------------
Clicking on any file name will cause the highlight bar to move
to the selected file name.  You can then click on the SELECT
gadget to select the file.   Double-clicking on a file name
will immediately select the file.

Click on the scroll bar or arrows to move the highlight bar
up and down.  Once the highlight bar reaches the top or bottom
of the list, the list will scroll through the other file names.

In a SAVE requester, clicking on the save name will invoke the
keyboard input to change the name.

Click on CANCEL to abort the file name selection.


File Requester (keyboard control):
---------------------------------
The cursor up/down keys will move the highlight bar up and down.
Once the highlight bar reaches the top or bottom of the list,
the list will scroll through the other file names.  Pressing
RETURN will select the file currently highlighted.

In a SAVE requester, pressing TAB will toggle between selecting
the file name from the list, or entering a new one in the space
provided.


- Setup Gadgets -

ADVANCED:
--------
Select the Machine ID you wish to use with the emulation.
This setting is unnecessary for most applications, however,
OS8.x requires the Machine ID be a Quadra series (700, 900,
or 950 can be selected).  If the Macintosh (the emulation),
shows an error stating something like, "This software can not
be used on this computer", try changing the Machine ID type.

If you are using Macintosh system software older than 7.5.0,
it may be necessary to set the Machine ID to be MacIIci.

The Startup Sound can be turned off or set to one of four
different schemes.  The default is "1" (the standard
startup sound).


VIDEO:
-----
Select the video driver(s) you wish to add to the emulation.

** Note: v1.0 of FUSION supports only 1 video driver, future
versions will support up to 6.

Selecting more than one will give you more than one video
driver (which can be used for up to six monitors).  Each
refreshed driver requires a good chunk of memory, though, so
only use more than one if you NEED to.

You cannot use more than one VESA driver if you have already
selected a "Direct" VESA driver.

For "REF" (refreshed) drivers, "Setup" allows you to modify the
FPS (frames/second).  For slower computers, you may wish to
lower this value to enhance the performance of the emulation.
The default is 30 FPS.

Future video drivers will have the ability to replace Apple's
QuickDraw routines, giving native video.  This ability is
selected in "SETUP", as QDXL Support (Y/N).



FLOPPY:
------
To select drive "A:" or "B:" or turn off the drive support,
select the appropriate option under either "Internal 0" or
"Internal 1".

To change the Auto-Detect Time, select the number of seconds
you want between head steps (or zero for off).

(If you turn off Auto-Detect, you will need to press both Shift
keys to indicate a floppy disk insertion.)

720K, 800K (psuedo-Mac), 1.44MB, and 1.68MB disks formats are
supported. 


DEVICES:
-------
To select a new HardFile, click the SELECT button.  To remove
a HardFile, click on the HardFile name in the list, then
click the REMOVE button.

The first HardFile in the list will always be the start-up
HardFile (the one that will always be booted up when you start
the emulation).  To re-order the HardFiles, remove all of them
except the one you want to start up from, then select the
others again.  Newly selected HardFiles will always be added
to the bottom of the list.

To delete a HardFile, click on OPTIONS and then click on DELETE
HARDFILE.  Now select the HardFile name you wish to delete
and confirm your decision.

To create a HardFile, click on OPTIONS and then click on CREATE
HARDFILE.  A file requester will appear, asking for the name
for the HardFile.  HardFiles can be any valid DOS name,
however, we would prefer you to use FUSION.HFx (where 'x' is
a number from 0 to 9).  The file requester will only show those
files have an ".HF?" extension.  Set the size of the HardFile
with the arrows, and then click CREATE again.  Creation is almost
instant, regardless of the size.  If there is an error while
creating the HardFile, a DOS error message will be displayed,
otherwise the previous menu will appear after the HardFile has
been created.



PORTS:
-----
To set up your modem and printer, select one port for each.
Click COM (for serial) or LPT (for printer).  You will
also need to set the unit of the device (for example, unit 2
for COM2).

Note that you can use the ports for two serial devices or for
two printers.

Select OFF if you do not want to use the port(s).



ROM FILE:
--------
Click the SELECT button, then select the ROM image file.  A
ROM image file *must* have a ".ROM" extension.

Make note of the ROM image file information supplied when you
select one.  This information could be useful if you discover
a problem with the emulation.  FUSION has been tested with
many different 512K and 1MB ROM images, however, due to the
numerous changes Apple has made over the years, it is possible
that you could have a ROM that Microcode Solutions has not yet
come across.  To prevent any possible problems, only use ROMs
(image files) having one of the following checksums (as shown
in the ROM selection menu):

512K - $368CADFE
       $4147DD77
       $350EACF0
       $35C28C8F
       $3193670E
       $36B7FB6C

1MB  - $06684214
       $064DC91D
       $F1A6F343
       $420DBFF3
       $ECBBC41C
       $3DC27823
       $FF7439EE
       $ECD99DC0
       $E33B2724
       $F1ACAD13



SOUND:
-----
To select your sound hardware, select either SB (Sound Blaster)
or WSS (Windows Sound System).  Select OFF if you do not want
sound support.

Make sure the settings for the Registers (Port/IRQ/DMA) are
correct.  Consult the documentation that came with your audio
card for more information about setting these Registers.

Selecting Sound Blaster will support Sound Blaster, Sound Blaster
Pro, Sound Blaster 16, and most Sound Blaster compatible boards.

Selecting WSS will support all WSS compatible boards.  The WSS
support requires a lot of overhead (not required by Sound Blaster
boards), so it should be the last choice.

*WARNING*   If you do not have audio support turned on, an
application that uses sound will run at about 1/10 the normal
speed.  Turn off the sound in the application (if possible)
to prevent the slow down, or turn on the audio support on.



CD-ROM:
------
To emulate a CD drive (using MSCDEX), select the drive letter
of the CD drive.  Set the Boot Priority to CD-ROM if you wish
to start up the emulation from the CD.

If you are using the CD drive as a SCSI device with ASPI, then
you should click the OFF setting here.

If you enable the CD support here, you will lose SCSI device 0
(in the SCSI support).  This is necessary because the CD-ROM
must be simulated as a SCSI device, even if an IDE/ATAPI CD-ROM
drive is being used.

You can select between one of two different CD-ROM drives (if
you have more than one CD-ROM drive installed in your machine).

You can not select more than one CD-ROM drive with the built-in
CD-ROM support.

If the boot priority is set to CD-ROM, the system will attempt
to boot from the CD-ROM drive.  Make sure that there is a valid
bootable CD-ROM disc in the drive *before* starting the emulation.

If the boot priority is set to DEVICE, the system may eject
the CD-ROM at boot time, depending on many factors.  This
operation is normal.



ADB:
---
To select whether to change KEYBOARD settings or MOUSE
settings, click that button.  A sub-window will appear from
which you can change settings for that part of the ADB.  To
return to the parent window, click the EXIT button at the
bottom of the sub-window.

(KEYBOARD:)

To change the keyboard layout to ISO (European), select ISO
under Layout.  Otherwise, the keyboard is assumed to be a
standard USA keyboard.

To use the BIOS for keyboard emulation, select BIOS.  (Note
that this will reduce the functionality of the keyboard.  See
below for more details.)  The default is DIRECT control.

To change which key is used for the COMMAND key, select it
under this heading.  If you use a keyboard with "Windows" keys,
and you are also using DIRECT Control, select the "WIN" option.
This will leave the Alts and Ctrls as they are and only use the
"Windows" keys for COMMAND keys.

(MOUSE:)

To change the action taken for the left or right mouse buttons,
select among these options.  You can choose whether to just
click or click while emulating the press of a key.

For example, to emulate holding the Ctrl key while clicking the
mouse button merely by just clicking the right mouse button,
select "Click+Ctrl" under Right Mouse Button.



SCSI:
----
To use SCSI, you will need to have installed the appropriate
ASPI driver(s).

Each SCSI device connected to your computer will appear in this
list.  If you wish the emulation to use it, click in the
"Enabled" column beside the device.  (It should change from "N"
to "Y".)

Note that the AppleCD extension for Mac OS 8.0 and later will
not work with a CD-ROM drive having a SCSI ID of 0.  This is a
bug in Apple's driver software.



NETWORK:
-------
To use your PC drives with the emulation, you first need to
install "PC Exchange" within the emulation.  Use the 
"Extensions Manager" Control Panel to locate "PC Exchange" and
make sure that it has been checked (enabled).

"PC Exchange" is bundled with Mac OS 7.5 or newer.  It was
available separately for System 7.1.

To select a drive for networking with the emulation, click in
the "Enabled" column beside the drive you wish to use.  (It
should change from "N" to "Y".)

Local drives (ones that are installed in your computer)
are shown as "local", while remote drives (ones that are on
a lan or other network system) are shown as "remote".

The lan software must install the drives are standard
controller drives to be shown as remote.  If drives are
mounted through a lan as strictly a volume, they will not
be accessible from the Macintosh desktop.

ALL of the partitions on a drive will be mounted and available
from the Macintosh desktop.  This support allows an easy
method of transferring files between the PC and the emulation.



MEMORY:
------
This is the LAST option you want to setup.  Since many different
options require varying amounts of memory, it is best to setup
everything else before setting the amount of memory you want the
Macintosh environment to use.  Refreshed video drivers require
2MB of RAM (for each driver), while direct drivers require no
RAM.  The ROM image size can be either 512K or 1MB.  There is
about 512K of overhead for the emulation.  So, expect to lose
about 3.0MB-3.5MB of RAM from your EXTENDED memory size.

If you change something elsewhere in the setup, and forget to
change the memory size, it will be automatically adjusted for
you if you exceed the amount of free memory remaining.

** WARNING **  Many Macintosh applications expect the RAM size to
NEVER change once the application has been installed.  It is a good
idea to figure out exactly how much memory you want to use, and
stick with that size.  Netscape is a good example of this problem..
if you install Netscape with a Macintosh environment having 32MB
of memory, and then reduce the memory size below 32MB, Netscape
will crash the Macintosh when you attempt to start it.



CONFIG:
------
When you finish changing your settings, you need to click on
SAVE CONFIG.  You can use alternate names for configurations,
but the emulation will only use the one called "FUSION.CFG".

To load a configuration, click LOAD CONFIG.  Then select the
file name you wish to load.

To delete a configuration, click DELETE CONFIG.  Then select
the file you wish to delete.

To delete a PRAM file, click DELETE PRAM.  Then select the file
you wish to delete.



SYSINFO:
-------
This tells you more about your computer.  It contains the
following information:

CPU Type - The type of CPU followed by the model and step
           versions.  FUSION requires a 486 or later CPU.

FPU Type - If a FPU is present (internal) or not (none).
           FUSION requires a FPU.

Free Memory - The amount of extended memory available.

Memory Speed - The speed at which non-cached READ transfers
               can occur.  The faster the memory speed,
               the faster the emulation.  This is the single
               biggest factor in the performance of FUSION.

DOS Version - Version and revision of MS-DOS.  V3.2 or later
              is required.

MSCDEX Version - Version and revision of the MSCDEX driver.

ASPI Version - Vendor string for ASPI driver (often contains
               version and revision information).
            
VESA Version - Version and revision of the VESA driver.
               V1.2 or later of VESA is required by FUSION.

Language - Current locale.

HARDWARE - A hardware diagnostic is performed while the FUSION logo
           picture is displayed.  The disagnostic looks at your PC
           hardware and determines if the low-level functions are
           working properly.  You should see 'PI:OK, 1024Hz'.  If
           you see values +/- 1 of the 1024 value, then you hardware
           is functioning correctly.  PI stands for Periodic Interrupt.
           This is a special interrupt that exists in your PC's real
           time clock circuitry, and it is rarely ever used by any
           PC software.  If your PI is defective, you would probably
           never notice a problem with your PC's normal operation.
           The PI is the 'heartbeat' for the emulation.  Without it,
           the emulation will not work.  The only way to fix a
           defective PI is by replacing the RTC (real time clock)
           chip, which most often means a complete motherboard
           replacement.

Any of this information may be critical toward solving any
problems that may occur with the emulation.  Make sure you give
us this information if you need to make a bug report.


After saving the configuration, exit the setup program
(ALT-X).  Now, type "FUSION" at the command prompt and the
emulation will start (or exit back to the command prompt,
displaying one of many possible error messages).

3) How to create a shortcut to FUSION for Windows 95

In Windows, locate Fusion.bat and right-click on it.  Then
select Create Shortcut.
	
Right-click on the shortcut and select Properties. Click on
Program, then click the Advanced button.  Now click on MS-DOS
mode, and make sure "Use current MS-DOS configuration" is
selected.

(If you need to change the contents of "CONFIG.SYS" or 
"AUTOEXEC.BAT" to get FUSION to work then you will need to
select "Specify a new MS-DOS configuration" and make sure the
space provided in the window contains the changes you require.)

Then click OK (for Advanced), and OK again (for Fusion
Properties).

If you have a command interpreter ("DOS Shell") like NDOS or
4DOS in your DOSSTART.BAT, you will need to remove it if you
want the shortcut to immediately run FUSION.  If you really
want to keep your "DOS Shell" then you will need to type EXIT
at the prompt when you start the FUSION shortcut.
_______________________________________________________________

4) How to exit or restart Windows 95

To exit Windows 95, click the Start button, then click Shut
Down.  Then click "Restart the computer in MS-DOS mode?"
Then click Yes.

To restart Windows, type WIN at the command prompt, or press
Ctrl-Alt-Del (if you use caching software that Windows does not
like, for example, you will need to restart your computer).
_______________________________________________________________

5) Possible mouse problems

If your computer has a built-in mouse driver then you need not
worry about the mouse.

Windows 95 uses its own driver for the mouse, so you may need
to modify the DOSSTART.BAT in your WINDOWS directory to get
FUSION to work with the mouse.

In Windows, locate Windows\Dosstart.bat and right-click on it.
Then select Edit.  Then add the following lines to the file:

	set mouse=c:\mouse
	c:\mouse\mouse.exe /q

If you do not have the DOS mouse driver nor a built-in mouse
driver, then you will need to see your retailer about getting
one for your computer.

If you find that the mouse operation is 'jerky', you probably
have a low DPI mouse or the scaling factor is set incorrectly
in your mouse driver software.  Consult your mouse driver
documentation for information on changing the x/y scaling.

6) How to get installed quickly:

	A)  Type "SETUP" (without the quotation marks) at the
	command prompt.

	B)  Click on the DEVICES gadget and create a big HardFile
        (100+ megs) and select it.

	C)  Make sure all the other settings are correct, then
	save the configuration and quit the setup program.  If
	you are starting up from a CD, you will need to use the
	emulated CD (and MSCDEX), and you will need to set the
	"Boot Priority" to CD-ROM.

	D)  Insert the "Disk Tools" disk (or Install CD).

	E)  Type "FUSION" (without the quotation marks) at the
	command prompt

	F)  The "Disk Tools" disk will now boot up.  If you are
	starting up from a CD, it should boot all the way to
	the Desktop.  (If not, then you will need to create a
	"Disk Tools" floppy disk on an actual Mac.)

	G)  Once you are at the Desktop, a dialog should appear
	asking whether you want to format the HardFile.  Tell
	it to do so and wait for the HardFile to initialize.

	H)  If you are starting up from a CD Install disc, skip
	to step M.  Otherwise, double click on the "Disk Tools"
	disk icon.

	I)  Drag the "System Folder" from the "Disk Tools"
	window onto the icon for the HardFile.  The Mac should
	now copy the folder and its contents to your HardFile.

	J)  Now select Restart from the "Special" menu.  When
	the screen goes blank, eject the "Disk Tools" disk.
	The HardFile should now boot.

	K)  If you plan to install from a SCSI CD drive, you
	will first need to install the proper CD driver onto
	the HardFile.  If your CD drive does not work with the
	standard driver that comes on the "Disk Tools" disk,
	then you may need to contact your manufacturer for a
	Mac CD driver (or your retailer for a standard
	commercial driver, like CD-ROM Toolkit).

	L)  If you are installing from floppies, insert the
	first Install disk.  If you are installing from CD,
	insert the Mac OS Install CD.

	M)  Double-click on the Installer icon and read the
	information presented to you.

	N)      OS 7.5:

	Look for a pop-up menu in the upper-left corner of the
	installer dialog when it comes up.  Change the setting
	from "Easy Install" to "Custom Install" and make sure
	that you choose "System for Any Macintosh" in the
	"System" category of the list that comes up.  You may
	select the other categories in general, but you must
	use the individual "System for Any Macintosh" in the
	"System" category.

		OS 8:

	Make sure you select "Options" and turn off the
	"Update Drivers" option.  Then select "Customize" and
	make sure you select the installers you want to run.
	When the Mac OS installer runs, look for a pop-up menu
	in the upper-left corner of the window.  Select the
	"Custom Install" option in this pop-up menu.  Then
	make sure you select "Universal System for Any
	Macintosh" in the list (among the other things you will
	need, like "Extensions" and "Control Panels").

	O)  Now select "Install" and wait for the installer to
	prepare (this always takes a few minutes).

	P)  If you are installing from floppies, make sure to
	stick around and change disks whenever needed.  If you
	are installing from a CD, this will take somewhere
	between 15 to 60 minutes (depending on the speed of
	your computer).

	Q)  When it is done a dialog will appear asking you to
	prepare for Restart.  Do so, and then hold the Shift
	key down until the "Welcome to Macintosh" appears.  It
	should also indicate that the extensions have been
	disabled.

	R)  When Finder comes up, you will want to select the
	Control Panels (in the Apple menu), and then double
	click on the "Extensions Manager" Control Panel.

	S)  When the list comes up, make sure to uncheck
	"A/Rose".  (See below for more on extensions.)

	T)  Once you have unchecked any potentially dangerous
	extensions, you may now do a normal Restart.  If you
	get an error message or if the Mac hangs up, you may
	need to force-shutdown (right-Alt-Pause) and then
	start the emulation with the extensions disabled (by
	holding down the shift key while booting).

7) How to create a ROM image file

To do this, you really will need to own an actual Mac or find
someone who legally owns a ROM image file and purchase their
ROM.

Note that it is illegal for you to have a ROM image without the
ROM itself.  Unless under strict written agreement with Apple, 
there is no way around this.  Do not borrow or lend ROM images!

Along with FUSION, we provide a utility called "ROMUtil".  Its
sole purpose is to create an image file when it is run on an
actual Mac.  As long as you do not use the Mac and the ROM
image at the same time, this is perfectly legal.

Please do not use ROMUtil on a machine that you do not own (such
as from your local library, Kinkos, or any other source).  Doing
so is illegal.

Make sure you give the ROM image a ".ROM" extension when you
name it.

DO NOT attempt to use the ROMUtil program on another Macintosh
emulation!  THIS WILL NOT WORK.  The ROM image file will be
corrupted.  You can only capture the ROM image from a real
Macintosh.
_______________________________________________________________

8) Notes on Extensions and Control Panels

You will not need all the Extensions and Control Panels.  Some
of them may cause problems.  Keep this in mind when you do a
normal Restart (with the extensions enabled).

You need to disable "A/Rose".  This extension causes some
serious problems if you leave it enabled.

Other Extensions and Control Panels will likely fail quietly,
but for your peace of mind, you may wish to disable them, and
save your system the bother:

	QuickTime PowerPlug
	QuickDraw 3D
	Graphics Acceleration (any kind)
	54xx/64xx Update
	Auto Remounter

	Button Disabler
	Cache Switch

In particular, anything that is designed to work only on
PowerMacs (like QuickDraw 3D), you can safely assume will not
work with FUSION.

9) Features of the floppy support

Auto-detection is what causes that "clunk...clunk" sound in
your floppy drive.  When you insert a disk, it automatically
appears on the Mac desktop.

To make the drive far less noisy, you can set the floppy
auto-detect time to OFF.  This will turn off head stepping, so
you will need to press both "Shift" keys when you insert a
floppy disk for it to be recognized by the Macintosh.

For more on why it makes that peculiar noise and how it works,
read the following explanation:

(For users:)

Floppy drives are about as old a technology as punch cards.
You would expect some limitations.  The upshot of how it works
is that you have to make the drive do something to know whether
a disk has been inserted.

We make it move the drive head back and forth.  This is far
less annoying than leaving the motor and the drive light on all
the time.  Unfortunately, it makes a little noise.  In
particular, if you work in a quiet atmosphere, it can be quite
noticeable.

(For programmers:)

Disk seeking updates the change-line status.  We perform this
feat once every 2 seconds (or whatever you have it set to).
Since this is done at the hardware level, you would think that
simply seeking all the way out and then sending a seek pulse
every 2 seconds would be enough to detect a disk (this is the
way "NoClick" on the Amiga works).  Alas, the drive controller
intercepts such attempts and returns "invalid function"
whenever you attempt to seek out from track 0.

10) Features of the keyboard support

You should really have an "extended" keyboard for full support.
An old keyboard will put you in "BIOS" mode which is a lot less
intelligent.  (See below.)

One nice feature of the keyboard support is the ability to use
the "Windows" keys as command keys.  (Now, if they just swapped
the positions between these and the Alts, it would look just
like a Mac keyboard.)

The keyboard (other than "Command" key) is mapped to equivalent
Mac keys with the following exceptions:

	* F13 is Print-Screen, F14 is Scroll Lock.
	* F15 is not mapped.
	* Pause (F15) is used as the "Power" key.  Mac OS 7.5.1
	  or newer lets you shut down using this key.  Press 
	  Right-Alt-Pause to force the emulation to shut down,
	  but avoid using the force-shutdown whenever possible.
	* The keypad = key is not mapped (it's not there!).
	* When using "Direct" mode, you can use Ctrl-Print-
	  Screen to snapshot the screen.  This will save into a
	  PCX-formatted image file in your FUSION sub-directory.

When using the BIOS to map the keyboard you should be aware of
additional problems:

	* The BIOS will not give F13 or F14 codes.
	* Rather than Pause, you will need to use Ctrl-Break to
	  switch off the emulation, but avoid using this if you
	  can.  Use the normal "Shutdown" if possible.
	* Many of the keys map in unexpected ways. Ctrl-J, for
	  example, maps as the Mac return key.  Keypad numbers
	  map as top row numbers.
	* Some key-combinations return no value at all.  Ctrl-
	  Period, for example, returns no code at all.
	* Ctrl-Alt-Del will reboot the PC.  Print-Screen will
	  attempt to print the screen.  Ctrl-Print-Screen will
	  toggle whether output is sent to the printer.
	* Since the BIOS does not send key-release messages,
	  the emulation cannot track how long a key is held
	  down.  So, if you hold down a key, the Mac will
	  receive key-repeats instead of the standard Mac key
	  held down.  (This will become quite obvious in games
	  and such.)
	* Using the Alt-### will likely have unexpected results
	  (if any).
	* LEDs are controlled by the Caps, Scroll, and Num lock
	  rather than by Mac system software programming the
	  ADB.
	* If the keyboard causes some beeping, the BIOS buffer
	  is full, and you will need to wait for it to empty
	  some more before continuing to type.
