                         LOADING

To load THE 64 Emulator, simply insert the disk into drive 0 (the built in
drive) and reboot your Amiga by pressing the CONTROL-AMIGA-AMIGA keys. The 64
Emulator cannot be run from the Workbench (by Icons) - you must reboot your
machine to load the program.

When loading The 64 Emulator, the program disk must be write protected (the
small hole showing), and all disk activity must be complete.  If the disk is
not write protected, then you will be prompted to write protect the disk
before the program will load.


                    SERIAL INTERFACE CABLE

The 64 Emulator is sold in three different configurations - without a serial
interface, with a serial interface for the Amiga 1000 or with a serial
interface for the Amiga 500 and the Amiga 2000.

The Serial Interface is a cable that allows a Commodore 1541, 1571, 1581 or
compatible disk drive to be connected to the parallel port on the back of the
Amiga.  With this interface, The 64 Emulator can access Commodore 64
peripherals that would not be otherwise compatible with the Amiga. The primary
advantage of using a disk drive such as the 1541 is increased compatibility
with 64 software and the ability to load copy-protected software.

Be careful when connecting cables and peripherals to your Amiga.
If cables are not plugged straight into the port, they can sometimes reset
your Amiga.

To attach your Serial Interface  to your Amiga, connect the wide end of the
cable to the parallel port on the back of the Amiga and the round end to the
back of the disk drive.  The difference between the Amiga 1000 interface cable
and the Amiga 500/Amiga 2000 interface cable is the connector on the wide end
of the interface.

Once you have connected the Serial Interface you will have to set the system
configuration to allow The 64 Emulator to access the serial devices.


                       CONFIGURATION EDITOR

The configuration editor allows you to customize The 64 Emulator to your
particular hardware.

To display the configuration editor, hold the CONTROL and press the HELP key
when The 64 Emulator is loaded.  A pop-up menu describing the current hardware
setup will appear over the top of the 64 program that is currently running. To
change any of the options, move the mouse pointer to the highlighted area
containing the current settings and press the left mouse button.  By
repeatedly pressing the left mouse button, the program will cycle through all
the possible settings for the selected option.

To exit the Configuration Editor without saving the settings, click on any
area outside of the Configuration Editor box.

SAVING THE CONFIGURATION SETTINGS

Once you have set all the options to correspond with your hardware, insert any
AmigaDOS disk and click on SAVE CONFIG option.  The current settings will be
saved to the diskette and can be loaded by clicking on LOAD CONFIG with the
correct disk in the drive.  Saving settings on The 64 Emulator disk will
change the defaults when you next load the program.

After the settings are saved, you will be returned to the current 64 program.
If the disk is write protected, the settings will not be saved and you will
remain in the Configuration Editor. Simply write enable the disk, reinsert the
disk, and click on SAVE CONFIG again.

When saving configuration setting to the program disk you must remember to
always write protect the disk after saving.

Note that you can change the configuration without saving the new settings to
disk.  This allows you to change options for different programs without having
to repeatedly save the configuration.


                  THE CONFIGURATION OPTIONS

DISK DRIVES

The 64 Emulator allows you to access Amiga floppy disks, hard drives and RAM
disk as well as Commodore 64 drives connected with the Serial Interface cable.
Disk drives are accessed during 64 emulation by specifying a device number
from 8 to 11 (up to four drives may be on-line at one time).  Using the
configuration editor you may assign each of the four drive numbers to any
combination of Amiga and 64 drives.

AMIGA DRIVES

Valid Amiga drive names are: DF0:, DF1:, DF2:, DF3:, DH0:, DH1:, DH2:, DH3:,
RAM:.  DF refers to the floppy disk drives (DF0: is the built-in drive), DH
refers to hard drives and RAM: refers to a temporary file that is created in
the RAM of the Amiga (RAM: requires at least 1 Megabyte of memory).

The 64 Emulator is also compatible with the Amiga 5-1/4" drive (Model 1020)
only in the AmigaDOS format.  It will not read Commodore 64 disks directly on
an Amiga 1020 drive.  A Commodore 64 compatible drive (such as the 1541) and
Readysoft Serial Interface Cable are required to read Commodore 64 disks
directly.

If you have chosen an Amiga drive, you may then select whether or not to
emulate a 1541.  Click on the prompt to the right of the drive selection to
toggle between Standard Amiga and 1541 Emulation.  If 1541 Emulation is
selected, a file called C1541 will be created on the disk in the specified
drive when you issue the format command from the 64 (see Disk Commands
section).  This file holds the same amount of storage as would a standard 1541
disk and will respond in almost exactly the same manner as a 1541 disk drive.

If the 1541 Emulation option is not selected, the drive will be less
compatible with some 64 software but you will have the full storage capacity
of the Amiga disks and be able to access files that are stored in standard
AmigaDOS format.  When the disk is not emulating a 1541, there are only two
file types, PRG and DIR. All program (PRG), sequential (SEQ) and user (USR)
will be displayed as program (PRG) files while Amiga sub-directories are
displayed as DIR.  Relative files are not supported when Standard Amiga is
selected.

To access an Amiga drive subdirectory, you must assign an unused device name
to the name of the directory you want to access in your startup-sequence.  For
example, if you want to access DF0:C64Programs as a sub-directory, you can
enter ASSIGN:DF3: DF0:C64Programs in your Startup-Sequence.  This allows Df3:
to access the sub-directory on your DF0: disk.  Note that DF3: may be replaced
with any unused device name, including DF0-3, DH0-3 and RAM:.

COMMODORE 64 DRIVES

Commodore 64 disk drives (with the Serial Interface) may be used by selecting
C64 as the drive type.

You may also access a Commodore 64 disk drive by device number other than the
number it is set to in the disk drive's hardware.  All Commodore disk drives
default is to device number 8.  If you want to use an Amiga drive as device 8
and the Commodore drive as device 9 (even though it is hardware device 8), you
could set the device 9 prompt in the configuration settings to C64 and the
device type prompt (beside it) to Serial Cable 8.  This would tell The 64
Emulator that whenever an access is made to device 9 to translate it to use
device 8 on the serial bus.

To access any drives when using The 64 Emulator, you must specify the
appropriate device number (8 to 11) it is assigned to when issuing disk drive
commands.  It is therefore possible to have (for example) a Commodore 64 drive
as device 8, Amiga floppy drive 0 as device 9, an Amiga hard drive as device
10 and a RAM disk as device 11.

PRINTERS

Printers are selected in much the same manner as disk drives.  There are two
device numbers (4 and 5) assigned to printers during 64 emulation.  Through
the use of the Configuration Editor, you can assign each of the two devices to
one of three printer types: Amiga parallel, Amiga RS232 or Commodore 64.

Amiga Parallel Printers

Amiga parallel printers are connected to the parallel port on the back of the
Amiga.  To select this type of printer, set the printer type to PAR:.

Amiga Serial (RS232) Printers

Amiga serial printers are connected to the serial port on the back of the
Amiga.  To select this type of printer, set the printer type to SER:.

Commodore 64 Serial Printers

Commodore 64 serial printers are connected to the parallel port of the Amiga
using the Serial Interface cable (or alternately connected to the 64 disk
drive which is in turn connected to the parallel port of the Amiga with the
Serial Interface cable).

MODEMS

The 64 Emulator supports any standard Amiga modem connected to the serial
port.  The 64 Emulator will not work with any Commodore 64 modems designed to
plug into the Commodore user port because the user port is not present on the
Amiga.

PORT CONFLICTS

As several of the peripherals mentioned above require the same Amiga port, a
potential conflict arises if two such devices are required to be on-line
simultaneously.  The two possible conflicts are between ReadySoft's Serial
Interface and an Amiga parallel printer and between a modem and an Amiga
Serial (RS232) printer.  If such a case arises, a prompt will appear asking
you to connect the device that the 64 requires.  Once the device is connected,
click the left mouse button to continue or if you don't want to use the
requested device, press the right mouse button to cancel the prompt.  The 64
Emulator remembers which device is currently connected and will only request a
change if a required peripheral is not connected to the Amiga.

MOUSE/JOYSTICK PORTS

The Amiga has two control (joystick) ports which can be configured to allow
the use of a joystick, the Amiga mouse or a light pen.  The ports must be set
for the peripheral that is currently in the port (joystick, mouse, or light
pen).  Otherwise input cannot correctly be read.

Joysticks

Many 64 programs require that a joystick be in a specific port (1 or 2).  If a
program appears not to be reading the joystick, first make sure the desired
port is set to read joysticks and if this is the case, try setting the
opposite port to read joysticks and connecting the joystick to the other port.

Mouse

The 64 Emulator allows you to select how the Amiga mouse is to be interpreted
by the 64: as a 1350, as a 1351 or as paddles.

The default setting for the Amiga mouse is Paddles.

Light Pen

When using a light pen with The 64 Emulator, it must be plugged into Port 1.
You must set the configuration for Port 1 to Joystick.

1764 RAM EXPANDER

The 1764 RAM expander is a device that allows 256K of RAM to be added to a
Commodore 64.  If your Amiga contains at least 1 Megabyte of memory, the
configuration editor will allow The 64 Emulator to simulate this device.  By
setting the option to ON, 256K of the Amiga's memory will be set aside to be
accessed as if a 1764 cartridge was connected.

MONOCHROME MODE

The 64 Emulator spends a significant amount of time creating Amiga video image
from the screens that the 64 specifies.  This process is complicated by the
variety of methods of generating color that are available on the 64.  When
the Monochrome mode is enabled, all text and high resolution images are
adisplayed with only two colors - green and black, just like a monochrome
monitor.  For programs that are very screen intensive but where color is not
essential, using the monochrome mode gives a noticeable speed increase.

BORDER

Due to hardware limitations of the Amiga, generating a border around the
entire screen would greatly slow down The 64 Emulator. As an alternative, The
64 Emulator allows you to select a border at the top and bottom of the screen.
The speed will not increase if the border is turned off, but it may make the
screen more attractive with some programs.

ALTERNATE CHARACTER SET

The Amiga displays a higher resolution than the Commodore 64.  This option
allows The 64 Emulator to use an alternate character set whose letters are
clearer than the standard 64 character set. To select the alternate character
set, change this option to ON.  Click the option again to turn it off.


                        BASIC COMMANDS

The 64 Emulator allows all Commodore 64 BASIC commands:

ABS, AND, ASC, ATN, CHR$, CLOSE, CLR, CMD, CONT, COS, DATA, DEF, DIM, END,
EXP, FN, FOR, FRE, GET, GET#, GOSUB, GOTO, IF, INPUT, INPUT#, INT, LEFT#, LEN,
LET, LIST, LOAD, LOG, MID$, NEW, NEXT, NOT, ON, OPEN, OR, PEEK, POKE, POS,
PRINT, PRINT#, READ, REM, RESTORE, RETURN, RIGHT$, RND, RUN, SAVE, SGN, SIN,
SPC, SQR, STATUS, STEP, STOP, STR$, SYS, TAB, TAN, THEN, TI, TI$, TO, USR,
VAL, VERIFY, WAIT.

This guide is not intended to be a reference for the above BASIC commands.  A
number of good books are available that outline how to use these commands.


                         THE KEYBOARD

As the Commodore 64 keyboard and the Amiga keyboard contain several different
keys, The 64 Emulator changes the functions of several Amiga keys to
correspond to keys that are required by the 64.  The following table outlines
the major changes:

AMIGA KEYS                            PERFORMS FUNCTION OF:

ESC                                   RUN/STOP
DEL                                   RESTORE
TAB                                   CONTROL
Left AMIGA                            COMMODORE Key
F10                                   HOME
Shift F10                             CLR
BACKSPACE                             DEL
Shift BACKSPACE                       INST

There are three Commodore 64 keys that perform no function unless pressed with
another key, these are SHIFT, CONTROL and COMMODORE. SHIFT is used to access
capital letters, graphic symbols and punctuation.  CONTROL is used with the
0-9 keys to change colors and many programs use CONTROL with a letter to
represent different functions.  The COMMODORE key is used with the 0-9 keys to
change color and with letters to generate alternate graphic symbols.  The
SHIFT and COMMODORE keys when held down together will toggle the screen
between upper case/lower case and upper case/graphics.

The RUN/STOP key (ESC on the Amiga) is used to stop execution of BASIC
programs and loading files.  If holding RUN/STOP does not stop the program,
hold RUN/STOP while pressing the RESTORE (DEL on the Amiga) and BASIC should
stop.  If this fails, pressing CONTROL, LEFT-ALT, and HELP simultaneously
should reset the 64 to BASIC, clearing the current program (as if the emulator
had just been loaded).  If this doesn't stop the program, you will have to
reload The 64 Emulator.


                        TRANSFER SOFTWARE

To make the transfer of software from 5-1/4" disks to 3-1/2" disks easier,
ReadySoft Inc. has included a transfer program on The 64 Emulator program
disk.

To load the transfer program, type:

LOAD"TRANSFER",10   <RETURN>
RUN     <RETURN>

If you have changed your device number, replace the 10 in the loading command
with the device number of the drive containing The 64 Emulator program disk.
This drive must be set to Amiga Standard in the configuration editor so that
the drive can read the transfer software.

The transfer software allows you to select which drive contains the disk you
want to copy from (the source disk), and which drive contains the disk you
want to transfer to (the destination disk).

Note that you must format the destination disk first (if it has not already
been formatted) from the WorkBench or CLI before loading The 64 Emulator.

By default, the source device is set to 8 which will copy from the Commodore
64 serial disk drive, and the destination is set to 10 which will copy to the
built-in Amiga 3-1/2" disk drive in Amiga Standard format.  If you need to
change the source device number press S, and if you need to change the
destination device number, press D.

Now select whether you want to make an exact copy of the disk or copy
individual files by pressing E or F.

If you select E, the copy will be more compatible with the 1541, but will be
slower than Amiga Standard when being accessed, and uses only 1/5 of the disk
space available.  The Amiga drive must be in the 1541 Emulation mode when
making an exact copy.  The copying will begin immediately.

If you select F, you may copy using 1541 Emulation or preferably Amiga
Standard on the 3-1/2" drive, which will increase speed and allow for all of
the available disk space to be used.  You will be asked for a directory
pattern (you may simply hit RETURN on this option).  The default pattern of *
will display the entire directory of the source disk when RETURN is pressed.
To select a file to be copied, move the cursor to the file name and press the
RETURN key (a Y will appear beside the name).  Repeat this procedure until all
the files that you want copied have a Y beside them.  To begin the copy, press
the F1 key.

If the software you want to transfer is copy-protected, the transfer software
may not copy it to 3-1/2" disk format.


                          LIMITATIONS

Due to the nature of The 64 Emulator, some programs will run between two and
five times slower than the Commodore 64, others will run at full speed.  This
slow-down will not be noticeable on all programs.  Games that allow you to
change the speed of play should be set at maximum speed to compensate.

Due to hardware limitations on the Amiga, sprites may, from time to time,
flicker or change color.  This is most noticeable when many sprites are close
to each other.

Most protected software requires the Serial Interface and a 1541 disk drive to
load the program.  This is due to the copy-protection employed by various
companies.  Even with a Serial Interface cable, some software may not load
with The 64 emulator if fast loaders are used as part of the protection.

The 64 Emulator requires complete control of the Amiga hardware, and as such,
multitasking is not allowed during the emulation.
