Hi, folks.

Here's an update of TETRIS to version 1.3 .

The changes (vs. version 1.0) are:
	- 2862 bytes, chksum #49FAh
	- Initial/pause screen (the reason for the incr. size ..)
	- increased speed (I hope :)
	- stone positions more close to the original

Installation:
    To install the game, a) download the ASC version, execute ASC\->, b)
    download the uudecoded version and recall it into the stack. Enter the port
    number (0,1,2) where you want to store it and press STO. Switch the HP48
    off, then on again. TETRIS13 will now be installed as a library named
    TETRIS. It uses the ID nr. 769. Normally, this number is used by the HP
    CASINO48 card, but I think TETRIS13 is the better choice.

Run/keys:
    To play it, enter the LIBRARY TETRIS menu and press the softkey named
    TETRIS or just type TETRIS [ENTER] at the command line. You will now see an
    initial screen. After pressing any key the game starts, coming up with the
    following screen:

	+-------------------------------------------+
	|SCORE         |   ##        |    TETRIS    |
	| 0            |   ##        |              |
	|LEVEL         |             |    ******    |
	| 0            |             |    *    *    |
	|LINES         |             |    ******    |
	| 0     ##     |             |              |
	|       ##     |             |              |
	||PAUSE|| PVT ||_____________||+LEVL|| QUIT||
	+-------------------------------------------+

	Symbol	Means

	******	is a little help screen for the motion control keys.
	*    *	Here they are:
	******		- Left arrow  : Move stone one step left
			- Right arrow : Move stone one step right
			- Up arrow    : Rotate stone
			- Down arrow  : Drop stone
			- VAR key     : 'Quick' move stone left
			- NXT key     : 'Quick' move stone rigth

	|xxxxx|	are softkey menu labels. The following softkeys are supported:
			- |PAUSE|     : Stop TETRIS until a key is pressed
			- | PVT |     : Toggle stone preview on/off
			- |+LEVL|     : Increment level
			- | QUIT|     : Force 'GAME OVER'

	##	is a stone.
	##

	The ON key can be used to leave TETRIS immediately.

Things to notice:
	1) If you get a 'TETRIS failed' from the game, please mail me a
	   description of the circumstances and the contents of the stack.
	2) I will maintain this program, so feel free to MAIL ME ideas for
	   improvement or notes of appreciation.

	   picture from it ..
	2) Chris Spell - inserted the UUENCODE form of TETRIS (thanks :-)
	3) W. C. Wickes - \->ASC

Enjoy,

[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-]
