  14.                                    ; This is a very small sample declaration ROM with the required board
  15.                                    ; sResource and a functional sResource (which is blank).
  16.                                    ; The board id and functional sResource types are especially bogus - your values
  17.                                    ; must be obtained from MacDTS, after sending in the required information.
  18.                                    ; Anyway, this file shows how to put together a ROM.  You also need
  19.                                    ; the Cards and Drivers book, with the source code for a ROM and driver.
  20.                                    ; Both are stripped down versions of the Apple Macintosh Video card ROM and
  21.                                    ; video driver aka the TFB board.  There are also other examples and exploded
  22.                                    ; drawings of declaration ROMs on the Developer Helper CD. Volume one is
  23.                                    ; known as "Phil and Dave's Excellent CD".  The examples, tools, and drawings are
  24.                                    ; also on AppleLink.  To get to them, go into (in order):
  25.                                    ;
  26.                                    ;  Developer Services bulletin board icon
  27.                                    ;     Developer Technical Support folder

  30.                                    ;             Card Dev tools folder
  31.                                    ;
  32.                                    ;
  33.                                    ; In the Card Dev Tools folder are other folders containing tools and
  34.                                    ; libraries.  These include:
  35.                                    ;
  36.                                    ; Examples folder            - contains example declaration ROMs, video driver,
  37.                                    ;                              source to a program like the GetsInfo program found
  38.                                    ;                              in the Slot Tools folder
  39.                                    ; Gamma Information folder    - contains documention discussing gamma table format.
  40.                                    ;                              This will be updated in later documentation for the
  41.                                    ;                              new 32-bit QuickDraw.  Eventually, the Cards and
  42.                                    ;                              Drivers book will contain the new gamma information,
  43.                                    ; NuBusTester folder        - contains a library to detect new ROMs with fixed
  44.                                    ;                              Slot Manager (Slot Manager that runs in 32-bit mode
  45.                                    ;                              as opposed to 24-bit mode)
  46.                                    ; Training Tools folder        - contains MacDraw drawings of exploded
  47.                                    ;                              configuration ROMs (like the existing Apple video
  48.                                    ;                              card ROM and the Apple EtherNet board ROM.
  49.                                    ;
  50.                                    ; Slot tools folder            - Inside, you'll find these tools:

  53.                                    ;                              the crc value of the assembled Declaration ROM file.
  54.                                    ;
  55.                                    ;                              Data - MPW tool takes the assembled file and strips
  56.                                    ;                              off the code 0 segment,leaving the code 1 segment
  57.                                    ;                              (the raw code).  The resulting file can then be
  58.                                    ;                              downloaded to a rom burning machine.
  59.                                    ;
  60.                                    ;                              Tjscomm - A small terminal program that can be used
