				 CHANGES
-------------------------------------------------------------------------------
V0.03pl4:
	* special release for computers with fast processor (pentium and
	  above)
		- uses model specific register for timing (time stamp counter)
		- may hang if an older EMM386 is installed (because the
		  EMM386 must emulate the rdmsr instruction!)
	* works on my new AMD-K6 and should run on Intel pentium and
	  pentium pro, may run on Cyrix processors
-------------------------------------------------------------------------------
V0.03pl3:
	* added some .T64 magic strings; recognized are now:
		- "C64 tape file"
		- "C64 tape image file"
		- "C64S tape file"
		- "C64S tape image file"
-------------------------------------------------------------------------------
V0.03pl2:
	* changed timing functions again, now it works on a DECstation 300
	  (which is a _really_ slow 386sx/16)
	* added -dump switch that enables screen dump on exit (saves into
	  'screen.txt')
	* commented out the waiting for ATN line zero on close commands again
	  (I have no idea what's the reason for this timeout errors)
-------------------------------------------------------------------------------
V0.03pl1:
	* fixed for use with monochrome displays
	* fixed port reading (waits till two sequential reads give the
	  same value)
	* optimized timing, now it runs even on my old 386sx/25 ;-)
	* added a screensaver
	* rudimentary command channel support, this is very unstable
	  but it allows directory listing with my Action Replay Cardridge
	  (if you have such a cardridge too, disable the floppy speeder
	  with the 'OFF' command and you can load files with the function
	  keys)
	* added int 0x24 handler to get rid of those annoying dos messages
	  if a device is not ready (i.e. A: without a floppy)

-------------------------------------------------------------------------------
V0.03:
        * added loader for LYNX archives (.LNX)
        * not very much tested (lacking different types of archives)

-------------------------------------------------------------------------------
V0.02:
        * completely rewrote the protocol handling routines
          (after checking the 1541 ROM listing)
        * timeout for all routines implemented, so no reset button
          needed anymore
        * saving disabled
        * 1.5 times faster than the real floppy
          loading 197 blocks takes 87 seconds instead of 132 seconds
        * can be used together with a real floppy
          (i.e. real floppy as device 8 and emulator as 9 to 11)

-------------------------------------------------------------------------------
V0.01:
        * first attempt to emulate the c64 serial protocol for
          use in a floppy emulator
        * lots of timing problems
        * need to press the reset button after protocol errors :-(
        * loaders for
          - filesystem
          - tape images (.T64)
          - disk images (.D64)
