1. Introduction

Thank you for purchasing Offbeat's Duplicator, a copy program of a very 
special kind, even though it's Public Domain. It copies any unprotected 
Atari ST disk (with 512 bytes per sector) in a remarkably high speed, either 
using one or two disk drives. Have a look at its features:

        - 100 % optimized Assembler Code
        - Delightfully designed control-panel
        - Magnificient Music
        - Gigafast Copyroutines
        - No Operating System Calls
        - Copies and formats 9, 10 or 11-sector disks
        - Reads disk format automatically if wished
        - All disks are converted to a hyperfast format
        - Optimum interleave and spiral factors
        - Multiple Write Option
        - Fast Format Technique
        - Viruses are idle while using Duplicator
        - Virus-killing Boot Code Utility
        - Soft Format Option
        - Steprate Selection
        - Hexadecimal & Decimal number Display
        - New, improved versions will follow soon...

2. The Control Panel

2.1 The Information Section

This is the area in the upper left corner. It displays the current track and 
side and whether Duplicator is reading, writing, formatting or doing a step 
(FDC Steps are very fast (usually 3 ms), so mostly the period of time is so 
short, that the step light is not enlighted).

2.2 The Error Section

The error section in the middle part gives you information if an error 
occured. There are four different kinds of floppy disk errors:

        - Timeout (Usually happens when there's no disk in the drive or the
                  drive is switched off)

        - Protection (Occurs when the write protection of a disk is set while
                     Duplicator tries to write or format a track)

        - Seek Error (Means that the current track or sector was not found by
                     Duplicator. It happens when you enter a wrong disk-
                     configuration or when you try to copy a protected disk)

        - CRC Error (occurs when a sector has a bad checksum. CRC stands for
                    Cyclic Redundancy Check. Most times several retries help)

If one of these error happens, you can choose one of the following options:
Retry ("R")  : Duplicator tries it again.
Skip  ("S")  : The track will be skipped.
End   ("ESC"): The whole action will be aborted

2.3 The Configuration Section

This section, which is placed in the upper right corner, shows you the actual 
disk-configuration. The sectors per track, the tracks per side and the sides 
per disk are displayed. You can change these parameters by pressing "INSERT" 
and "LEFT" for the sectors per track, "UP" and "DOWN" for the tracks per side 
and "CLEAR" and "RIGHT" for the sides per disk. The values are taken for the 
format-option and for the duplication, in case the GET FORMAT-light is idle.

2.4 The Options Section

The Options Section is placed right under the Error Section. You can toggle an 
option simply by pressing the indicated key.

        - Get Format ("G") (Reads the disk configuration from the disk)
                           For Duplicating

        - Multiple ("M") (Allows you to write the disk contents several times)
                         For Duplicating

        - Format ("F") (Formats the destination disk)
                       For Duplicating

        - Verify ("V") (Verifies whether the written data is correct or not)
                       For Duplicatin

        - Quick ("Q") (Uses the fast format routine)
                      For Duplicating and Formatting

        - Source ("S") (toggles the source disk drive)
                       For Duplicating

        - Destination ("D") (toggles the destination disk drive)
                            For Duplicating and Formatting

2.5 The Steprate Section

This section simply inlcudes the step rate selection. You can change the 
steprate from 2 to 12 ms by pressing the keys "7" and "(" for disk drive A and 
"8" and ")" for disk drive B.
Usually a step rate of 3 ms is the best. Some drives are also capable of using 
a 2 ms step rate, but there is hardly any change in the speed. 5 1/4 inch 
MS-DOS drives need a 12 ms step rate.

2.6 The Preferences Section

There are three things to change in the Preferences Section. If you press 
"F1", you toggle between hexadecimal and decimal number output. "F2" will 
change between 50 and 60 Hertz display and "F3" allows you to turn the music 
on and off.

2.7 The Selection Section

The section with the nice name offers you the six functions of Duplicator. 
Press "SPACE" to copy a disk, "RETURN" to format a disk, "DELETE" to 
soft-sormat a disk, "ENTER" to write the Duplicator Boot Code, "HELP" for some 
information and "ESC" to quit from Duplicator. You can press "ESC" while 
copying or formatting, as well. This will just abort the action in service, 
but not quit.

3. The Functions

3.1 Duplicate Disk ("SPACE")

copies a single or double sided, 1 to 11 sector disk with 1 to 90 tracks. 
Press any key after you inserted the source or the destination disk. There 
might be some problems with Duplicator on one meg STs with the memory, because 
there are not more than two disk-changes. So, a very dense formatted disk will 
not fit into the memory and make Duplicator crash (e.g. a 82 Tracks, 11 
Sectors, double sided disk)

3.2 Format Disk ("RETURN")

formats a blank or used disk, which has to be in the destination drive, with 
the given parameters of the Configuration Section. Well, there's nothing 
special to say about this option.

3.3 Soft-Format Disk ("DELETE")

erases the directory of the disk in the destination drive. You can select 
whether you want to apply one or two sides in the Configuration Section. If 
you want to use a disk, which has been formatted once, you can just 
soft-format it, instead of formatting it, which takes much more time.

3.4 Write Bootcode ("ENTER")

This function writes the Duplicator Bootcode to the destination drive. The 
bootcode is a small utility, which is present in the bootsector. Every time 
you boot from a disk with the bootcode on it, the utility is started. It 
changes to 60 Hz on colour monitors (if you want to keep 50 Hz press 
"ALTERNATE" while booting). If the most-spread virus, the so-called 
"Ghost-Virus" or "Mouse-Virus", is in the memory, the Duplicator Bootcode 
kills it in the RAM and in the reset-resistent memory. That means, that you'll 
never have problems again with the Ghost-Virus! If any other virus is in the 
memory, the bootcode writes a message and forces you to switch your computer 
off for 5 to 10 seconds. The Duplicator Boot Code runs on colour and 
monochrome monitors.

3.5 Help ("HELP")

If you press "HELP", a screen with some information is displayed. Press any 
key to go back to the main menu.

3.6 Quit ("ESC")

quits from Duplicator without doing a security check.

4. Plans for Future Versions

As you read, there'll be future versions of Duplicator. These are the planned 
improvements and changes:

        - Disk changes (see 3.1)
        - Verify-option
        - Fully compatible MS-DOS format
        - Keyboard Repetion
        - complexe Virus Recognition
        - TT-Support (High Density) (far away)
        - Track Shaker (Get used sectors only)
        - Monochrome Support
        - Disk Names
        - Display of rounds per minute
        - Disk to File/File to Disk Conversion
