      FORMAT OF gestaltATalkVersion RESPONSE
      --------------------------------------
      The version is stored in the high three bytes of the response value.  Let us number
      the bytes in the response value from 0 to 3, where 0 is the least-significant byte.
  
          Byte#:     3 2 1 0
          Value:  0xMMNNRR00
  
      Byte 3 (MM) contains the major revision number, byte 2 (NN) contains the minor
      revision number, and byte 1 (RR) contains a constant that represents the release
      stage.  Byte 0 always contains 0x00.  The constants for the release stages are:
  
          development = 0x20
          alpha       = 0x40
          beta        = 0x60
          final       = 0x80
          release     = 0x80
  
      For example, if you call Gestalt with the 'atkv' selector when AppleTalk version 57
      is loaded, you receive the long integer response value 0x39008000.

      The gestaltNativeCPUtype ('cput') selector can be used to determine the
      native CPU type for all Macs running System 7.5 or later.
  
      The 'cput' selector is not available when running System 7.0 (or earlier)
      on most 68K machines.  If 'cput' is not available, then the 'proc' selector
      should be used to determine the processor type.
  
      An application should always try the 'cput' selector first.  This is because,
      on PowerPC machines, the 'proc' selector will reflect the CPU type of the
      emulator's "virtual processor" rather than the native CPU type.
  
      The values specified below are accurate.  Prior versions of the Gestalt
      interface file contained values that were off by one.
  
      The Quadra 840AV and the Quadra 660AV contain a bug in the ROM code that
      causes the 'cput' selector to respond with the value 5.  This behavior
      occurs only when running System 7.1.  System 7.5 fixes the bug by replacing
      the faulty 'cput' selector function with the correct one.
  
      The gestaltNativeCPUfamily ('cpuf') selector can be used to determine the
      general family the native CPU is in. This can be helpful for determing how
      blitters and things should be written. In general, it is smarter to use this
      selector (when available) than gestaltNativeCPUtype since newer processors
      in the same family can be handled without revising your code.
  
      gestaltNativeCPUfamily uses the same results as gestaltNativeCPUtype, but
      will only return certain CPU values.

              Macintosh LC                "MacLC"
              Macintosh Performa          "Performa"
              Macintosh PowerBook         "PowerBook"
              Macintosh PowerBook Duo     "PowerBookDuo"
              Power Macintosh             "PowerMac"

          The following table contains lineNames for some discontinued lines:
  
              Line                        lineName

              Macintosh Quadra            "MacQuadra" (preferred)
                                          "Quadra" (also used, but not preferred)
              Macintosh Centris           "MacCentris"
  
      Model Numbers
  
          The modelNumber is a string representing the specific model of the machine
          within its particular line.  For example, for the Power Macintosh 8100/80,
          the modelNumber is "8100".
  
          Some Performa & LC model numbers contain variations in the rightmost 1 or 2
          digits to indicate different RAM and Hard Disk configurations.  A single
          machine type is assigned for all variations of a specific model number.  In
          this case, the modelNumber string consists of the constant leftmost part
          of the model number with 0s for the variant digits.  For example, the
          Performa 6115 and Performa 6116 are both return the same machine type
          constant:  gestaltPerforma6100.
  
  
      OLD NAMING CONVENTIONS
  
      The "Underscore Speed" suffix
  
          In the past, Apple differentiated between machines that had the same model
          number but different speeds.  For example, the Power Macintosh 8100/80 and
          Power Macintosh 8100/100 return different machine type constants.  This is
          why some existing machine type constant names take the form:
  
              gestalt<lineName><modelNumber>_<speed>
  
          e.g.
  
              gestaltPowerMac8100_110
              gestaltPowerMac7100_80
              gestaltPowerMac7100_66
  
          It is no longer necessary to use the "underscore speed" suffix.  Starting with
          the Power Surge machines (Power Macintosh 7200, 7500, 8500 and 9500), speed is
          no longer used to differentiate between machine types.  This is why a Power
          Macintosh 7200/75 and a Power Macintosh 7200/90 return the same machine type
          constant:  gestaltPowerMac7200.
  
      The "Screen Type" suffix
  
          All PowerBook models prior to the PowerBook 190, and all PowerBook Duo models
          before the PowerBook Duo 2300 take the form:
  
              gestalt<lineName><modelNumber><screenType>
  
          Where <screenType> is "c" or the empty string.
  
          e.g.
  
              gestaltPowerBook100
              gestaltPowerBookDuo280
              gestaltPowerBookDuo280c
              gestaltPowerBook180
              gestaltPowerBook180c
  
          Starting with the PowerBook 190 series and the PowerBook Duo 2300 series, machine
          types are no longer differentiated based on screen type.  This is why a PowerBook
          5300cs/100 and a PowerBook 5300c/100 both return the same machine type constant:
          gestaltPowerBook5300.
