============================ README.TXT ======================================

- This file describes the features that have been added to DiskDupe since
  the manual was printed.
- If the description shows "Pro" it also applies to "AutoPro".

===============================================================================

Diskdupe Version 5 to 8 are fake versions
So I jump the version and become version 9
Revision 0 to 8 are internal use only

=============
Version 9.09
12/24/93
=============
- Newly re-written disk read/write/compare routine, 15 times faster!
- 4 color scheme available, user selectable
- No opening screen delay, faster start-up
- Improvement in disk image handling
- 64-bit CRC checksum in disk data read/write/compare, more reliable
- Support slower floppy drive such as IBM PS/2 lines
- Support faster floppy drive such as PowerPC lines
- MAC, MIPS, Alpha & PowerPC disk support!
- Copied disk are special coded to make it read faster.
- Simulataneous disk read/write (require disk controller from MSD)

=============
Version 4.07
5/4/93
=============

Serializing Sets - Pro
----------------------
DiskDupe now increments the serial number only when copying a disk that
contains a serial number. This makes it easy to duplicate sets of disks
when only the first disk gets serialized.

=============
Version 4.06
3/11/93
=============

Window Margin - AutoPro
-----------------------
Added support for the Window Margin circuit on the Costas SDS controller.
This feature can be found in the "SDS Ctrlr" menu under the "Setup" menu.

=============
Version 4.05
3/4/93
=============

Code and Buffer CRC's
---------------------
Added checks to the DiskDupe code, disk buffers and image files to guard
against memory problems. Error 906, "Buffer memory has been corrupted"
indicates the image file was changed or that the memory in your computer
might be bad. Error 907, "Code memory has been corrupted" indicates that
there might be a problem with a TSR writing over the DiskDupe code. Either
of these errors indicate a serious problem which should be fixed.

Costas SDS Controller - Pro
---------------------------
Added support for the Costas SDS controller.

=============
Version 4.04
1/26/93
=============

DMA Burst Mode - AutoPro
------------------------
If using 2XSDS drives and "Error 205, DMA error" appears, change
DMA Burst Mode to On. Otherwise set it Off. "DMA Burst Mode" is
under "SDS Ctrlr" under the "Setup" menu.

Serial Cable - AutoPro
----------------------
DiskDupe AutoPro now supports 3 wire serial connections to the
autoloader. This is the default and works fine with most autoloaders.
If you get an "Error 402, Autoloader not responding", and you know
the cable is hooked up correctly, try changing Use CTS to No. "Use CTS"
is under the "Autoloader Port" under the "Setup" menu.

=============
Version 4.03
12/29/92
=============

/DAT Improvements
-----------------
The command line option /DAT can now be used anywhere on the command line
and all other command line parameters will override the information in
the specified data file.

=============
Version 4.02
12/1/92
=============

SDS and 2XSDS Support - AutoPro
-------------------------------
Added support for Simultaneous Double Sided (SDS) drives and 600 RPM
SDS (2XSDS) drives. To use SDS drives, select the appropriate drive
under the Setup menu and then select the SDS Ctrlr option. The SDS Ctrlr
board should be jumpered for either DMA 1 or DMA 3 and no IRQ.

Regular double speed drives (600 RPM) appear on the menu as "360k 2X",
SDS drives appear as "360k SDS" and 2XSDS drives will appear as "360k 2XSDS".

Be sure to run Diagnostics under the Go menu to make sure your computer
is capable of supporting SDS drives. If diagnostics reports a DMA error,
try increasing the bus speed of your computer. If you get an error 301
compare error, try turning off DMA Burst Mode.

=============
Version 4.01
11/9/92
=============

Ashby Loaders - AutoPro
-----------------------
Added support for Ashby loaders.

AutoLoader Sensor - AutoPro
---------------------------
Some Mountain loaders have a bad disk sensor. In this case, DiskDupe
would copy the first disk but on the second disk report "Error 403,
Bad autoloader command"

To circumvent this, use the command line switch "DISKDUPE /ALSENSORNO".
This only has to be done once. To reverse this use "DISKDUPE /ALSENSORYES".

=============
Version 4.00
10/6/92
=============

All features are described in the manual.
