>>> IDEfile Version History <<<
                  =======================

V1.01:	(Feb 2004) first really working version:
	* Apple /// access works
	* Lisa Boot ROM access as internal drive sometimes hangs with "10726" 
	  or "10737" error. System will boot after 2-3 tries
	* Lisa Boot ROM access as external drive does not work !!!
	* LisaOS access as internal drive works
	* Macworks XL access works 
	  (MacWorks does only support internal drives)
	* ProFile and ProFile 10M emulation works
	* Widget-10 and Widget-20 emulation does not work !!!
	* proprietary file system on HD, no FAT support
	* data backup through Linux dd command

V1.02:	(Apr 2004) some bugs fixed:
	* Now 2nd handshake is done before LCD & serial output. Lisa's 100ms 
	  timeout caused errors during Boot ROM access. IDEfile works now as 
	  an internal or external ProFile or ProFile 10M drive.
	* Widget-10 and Widget-20 emulation still does not work !!!
	* IDEfile shows "Volume X ready" message on LCD after 5s idle
	* Diagnostic versions have "Vx.xxD" version number

V1.03:   (Jun 2005) new features:
        * "c" command dumps seven bytes instead of six to support the 
          mysterious Widget commands
        * "e" command changed to make entry of consecutive bytes easier.
        * "v" command without parameter now displays volume table (former "s" 
          command).
        * "l" command added, this toggles Trace (List) mode. TraceFlag 
          assembler option (to create Diagnostic versions) deleted.
        * "z" command added, this erases the current volume.
        * "s" command now sets a time after which the HD shuts down (standby).
        * Failsafe concept has been optimized and system error messages have 
          been shortened to 16 characters. Fatal errors are now reported through 
          the serial port, too. 
        * HD initialization procedure revised to cope with ancient drives that 
          do not like a software reset command during their startup phase: Now 
          an IDE reset is issued only if the drive does not react within 10s. 
          HD timeout has been increased to 20 seconds.
        * LCD initialization changed to single-line only. This results in 
          better contrast and improves compatibility with "cheap" 1x16 LCDs 
          hat do not have a HD44100 chip. These displays address the first 8 
          characters as "line 1" and the rest as "line 2" when initialized to 
          two-line mode!!
        * Widget spare table changed. Widget emulation still does not work due 
          to the missing $26 & $13 commands, but drive is now recognized 
          properly by LisaTest.
        * Volume table can be addressed as "block FFFFFD".

V1.04:   (Aug 2005) bugs fixed:
        * "t"-"s" command also showed help text when /PCmd=0. 
        * IDE sleep timer interrupt turned off DMA in interface debug "t" mode.
        * Serial input routines reorganized.
        * Volume number can be read & volume can be changed via "block FFFFFC".

V1.05:	 (Apr 2006) new features:
	* Volume manager code reorganized.
	* XData block copy routine for IDE_RdSector, IDE_WrSector optimized --
          now 30% faster. Zapping a 5MB volume takes 1:28 min instead of 2:07, 
          Apple ProFile Certify needs 1:09 min instead of 1:28 for 10MB.
	* "IDEfile-16" and "IDEfile-32" volumes added for MacWorks.
	* "k" command added to copy one volume into another.
