TETRIS
                          by Fran Dachille

     This is my first release of the famous Tetris game on the HP48S. I was
inspired by the lack enjoyable games for our favorite handheld.  [Not since the
Goodies Disks have been available!  -jkh-]  This game, though it lacks some of
the whistles and bangs of fancy versions, performs on par with quality arcade
versions (nota bene -> SPEED).  At my college, every person who picks up my
calculator is immediately hooked for hours.

     This version is written for the CHIP48 game interpreter (c)
copyright 1990 Andreas Gustafsson.  To install Tetris,

           a) download TETRIS 
           b) evaluate the TETRIS directory
           c) download CHIP48 to that directory **
           d) make sure CHIP48 is in capital letters
           e) evaluate PLAY.

[Note: CHIP48 is available on EduCALC Goodies Disk #1.  If you would
rather use SCHIP, you should first edit the PLAY program, changing its
very last command from CHIP48 to SCHIP.  -jkh-]

     The game is best played with the thumbs while holding the
calculator.  The 4 key is left rotate, 5 - left move, 6 - right move, 1
- drop, ENTER - restart, DROP - end.  After every 5 lines, the speed
increases slightly and peaks at 45 lines.

     There is room for improvement in this version.  Notably, background
pictures, a pause key (for now, hold ON), two rotate keys, various
starting skill levels, a B version which starts with randomn blocks,
finishing graphics, and high scores, just to name a few.

     In order for improvements, I need to know if there is reasonable
demand.  If this game is worth playing for hours upon hours, please let
me know.  If you wish to support the improvements, want future versions,
and want to see other games ported to the HP48S, send $5.00 to:

[Note: some people emailed me saying, "Enough Tetrises!!!".  I'm only including
 these two versions of Tetris on this Goodies Disk because they are new ways of
 doing it, and they're short enough not to worry about.  -jkh-]
