Changes to V3.18 (10/08/93)
--------------------------------------------------------------------------
* Corrected all timing problems related to sound.  We tested extensively
  on programs that had known to be problems in the past.  MANY different
  configurations were tested for hours without a single problem!

* Added parity hardware emulation.  This simulates the RAM parity checking
  circuitry built into 512K and later ROMs.  Since we are getting ready to
  release 32 bit cleaned ROM support, many of the 512K ROM features have
  been added (such as parity checking) to insure 100% compatibility.

* Added support for the Piccolo and EGS-28/24 Spectrum video boards.
  We added this support before, however, we goofed and gave you the
  WRONG screen name (see 'EMPLANT.history for previous screen name).

  NOTE: The screen name must be defined as the following for EITHER
  the Piccolo or the EGS-28/24 Spectrum board (same driver for both
  boards):

  PICOa:VGA 640x480
  PICOa:VGA 1024x768
  PICOa:VGA 1280x1024

* Added support for the Merlin video board.  This board beats every
  board on the market to date as far as raw speed with EMPLANT's
  MAC emulation.  Only a 640x480x256 driver is included.  We are
  waiting for a replacement Merlin board (ours went bad...might of
  been us hammering it into the Zorro slot).  :-)  We were able to
  create the driver even though we could not see the display clearly
  (bad RAM, we think).

* Added support for the Rainbow II video board.  This is a rather
  interesting board in that it only supports 768x536 in 24 bit.
  When you use this driver, you will not see the 'Welcome to Mac...'
  message.  This is because in order for the 256K ROM'd MAC to
  use 24 bit displays, 32 bit color quickdraw must be loaded, which
  does not happen until well after the system is loading.

* Changed the SYBIL hardware support slightly.  Now, when you flip
  screens and switch the floppy 'ownership' between MAC and Amiga,
  the SYBIL hardware (if selected) toggles off for 'Amiga' and on
  for 'MAC'.  This allows you to use the parallel port on the Amiga
  side... SYBIL blocks the parallel port when it is enabled.
