Assorted geeky stuff...


  Palette files
    pal_enh = 'Enhanced' printout palette
    pal_inv = 'Inverted' printout paletee
    pal_ttx = Teletext colour palette (for WIMP)

    In PRINT# format:
      16 words for the colour entries, in the format
      &<blue><green><red><alpha>

      The alpha byte is &10.

      The colour ordering is standard:
        White, Grey1 to Grey6, Black, Blue, Yellow,
        Green, Red, Cream, Khaka (used for magenta),
        Orange, Cyan.


  ansitable
    512 byte file, used as a dual 256 byte lookup
    table. The first 256 bytes are the standard
    translations, and the second 256 bytes are the
    translations to use for graphics mode.
    Characters 0-31 and 127 should not be looked
    up, so 'X' is returned.



  helpfrms
    Help frames and lookup table.

    First word is number of frames available.

    Then, repeating for each frame, is a word for
    the frame offset.
    First byte (?0) is frame number (no subframes
    allowed). The rest of the byte (!0>>8) is the
    offset into this file.

    Following, comes the frame data, standard 1080
    byte blocks.
