QUADRIX  © Geoffrey Sparks 1991/92.
                -----------------------------------



  QUADRIX is Shareware. This demo version featuring 50 levels can be 
freely distibuted as long as all files are included and no material is 
altered in any way. A reasonable fee may be charged for copying in line
with the standard set by most PD libraries.
  The game concept, graphics, code etc may not be altered or duplicated 
in any way except as above.

  WARNING: Quadrix is currently (Feb. 1992) PAL only. I make no claims 
for its appearance on NTSC machines, (sorry).

  OK....   So you've played the game and had a bit of fun. Well now 
things get serious. For the princely sum of $20 Australian dollars,
( sort of like play money really! ), you can become a registered user
of QUADRIX. On receipt of your cash ( international money order, cheque
drawn on a bank with Australian offices etc. ) you will be rushed by 
air-mail the very latest version of Quadrix... including...


    1. 100 new and perplexing levels, taking off from where you should 
       have finished in the demo version.
    
    2. A complete, easy to use level designer. Create new levels and
       amaze your friends...( amaze yourself!! ). Good fun.
       Full instructions included.      
    
    3. All the source code you could ever need. Thats right! The 
       complete, unexpurgated story of one puzzle game's struggle to
       be born. Occassionally annotated, often amusing and 
       frequently revealing. Many hints and tips for using AMOS and
       how to combine a bit of assembly language when needed. Over
       35 pages in all - an offer too good to refuse.
    
    4. Peace of mind. Well if you play the game a lot you should 
       really fork out the asking price.

    5. Code word to allow the sub-game to be played as a separate 
       game.

    6. Possible discounts on any other games I write - ( well I 
       havent actually got as far as a sequel yet - but if this 
       does well ... who knows.)

HISTORY.
      
       Quadrix was originally conceived and written on the C64 a 
couple of years ago, with a slightly different format and minus the
sub-game.
       With the purchase of an Amiga and a copy of AMOS, along with 
several technical manuals and a copy of the PD  A68K assembler, work
started on upgrading to the 16 bit world. Along the way I learnt a lot
about the AMIGA, AMOS, 68000 machine code, Deluxe Paint, MED and 
most of all memory management - getting Quadrix to run in 512K was 
some task.
       This version was completed around the beginning of 1992, about 
6 months after deciding to re-write it for the AMIGA.



THANKS.
    
      Many thanks to Jan Clark for loads of play testing and lots of
extra levels, as well as innumerable helpful suggestions and advice.


TECHNICAL STUFF.

      Quadrix was written on an off the shelf, department store A500,
with a ram expansion card [ includes clock! ], and an extra floppy 
drive, ( I hope this isn't too technical for you.). The language was AMOS,
compiled with the AMOS compiler. Machine code was written using MEmacs,
assembled with A68K, and linked with Blink.
      No hard drives, cross-assemblers, accelerators, esoteric compilers,
IBM's, MAC's, Amiga 3000's, Devpacs, Lattices or trick photography was
used at any point.
