Welcome to the PC-Dragon V2.06beta upgrade. This package upgrades your current
PC-Dragon II setup to V2.06beta by replacing four of the executables and
adding one which is new. Two new text files are also provided, although the
main PC-Dragon manual is not updated by this upgrade - please see the notes
below for a summary of the changes.

To use the PC-Dragon V2.06beta upgrade you must already have installed a
previous version of PC-Dragon II such as pcd202a.zip; you should then simply
unzip this upgrade over your existing installation. For example, you could
type the following commands:

                             C:
                             CD \PCDRAGON
                             PKUNZIP -D \PCD206U

This assumes that you originally unzipped PC-Dragon II into the directory
C:\PCDRAGON with the -D option, and that your copy of this upgrade is in the
root directory of your C: drive.

The original PC-Dragon II usage restrictions apply to this upgrade. By using
the upgrade you accept these conditions.

This upgrade has not been tested very thoroughly - so please report any bugs
to "t3@mindless.com".

The changes since PC-Dragon V2.02 which have been incorporated into this
upgrade are detailed below.

DRAGON.EXE
==========
 o Now provides emulation of disk drives. Please see DISKS.TXT for full
   details. From v2.06 the emulator prompts for confirmation before exit or
   certain file operations if there may be unsaved virtual disk data which
   could be lost.

 o Bugs in the display of screens based in the upper 32K RAM have been fixed.

 o Now defines text mode graphics characters so that they are the same as
   a real Dragon or CoCo. If run in a DOS box under Windows, this feature
   usually only operates correctly in full-screen mode. It may be disabled
   by using the /NG command line option. The "Gfx=" setting on the information
   screen (CTRL-F10) indicates whether the feature is on or off.

 o Now accepts long filenames when run in a DOS box under Windows 95/98.
   Spaces may also be used in filenames, but the other additional characters
   remain forbidden. Please note that command line arguments containing
   spaces must be enclosed in double quotes. If long filenames are available
   then "Filename Prompt:" will show "(LFN)" on the information screen.

 o Minor improvements have been made to the PC joystick handling (slightly
   more accurate and future proof). Also, previous upgrades always gave a
   division by zero error which has been fixed from v2.06.

 o A bug in the printer status translation has been corrected.

 o A bug in the code which updates the keyboard rollover table has been
   corrected.

DC.EXE
======
 o Now accepts long filenames when run in a DOS box under Windows 95/98.
   Spaces and the other additional characters may also be used in filenames
   so long as the filenames are enclosed in double quotes.

 o Now accepts relative pathnames and filenames with multiple extensions.

 o Now prompts before overwriting files.

WHATIS.EXE
==========
 o Can now display some information about virtual disk files.

 o Now accepts long filenames when run in a DOS box under Windows 95/98.
   Spaces and the other additional characters may also be used in filenames
   so long as the filenames are enclosed in double quotes.

 o Now accepts relative pathnames and filenames with multiple extensions.

 o Can now recognise and describe T3.INI (the T3 emulator settings file).

 o A bug causing the program to hang when examining virtual cassette files
   with the character 'C' between blocks has been fixed.

COPYCAS.EXE
===========
 o Now accepts a long filename for the second argument when run in a DOS box
   under Windows 95/98. Spaces and the other additional characters may also
   be used in this filename so long as it is enclosed in double quotes.

 o Now displays the old and new header filenames as confirmation of the
   renaming that has been performed.

 o Now prompts before overwriting files.

VCOPY.EXE
===========
 o This is a new tool for reading and writing Dragon floppy disks in PC floppy
   drives. Please see VCOPY.TXT for full details.
