INCLUDES SOURCE CODE AND PORT FOR IBM-PC


-- Contents of Package --
Included in this package is the group file for the TI-83, the source 
code for TASM, and the IBM-PC port.  Instructions for the IBM-PC port
are included in the source file INTRUDERPC.ASM.

INTRUDER.83G	Upload to TI-83
src.zip		Source code for TI-83 version for assembly with TASM
INTRUDER.COM	IBM-PC port.  Runs under DOS or Windows.
INTRUDERPC.ASM	Source code to IBM-PC port assembles with MASM.


-- About v1.1 --
This was my first and only asm game for a TI graphing calculator.
Recently I came across the source code and it reminded me of
the good ol' days.  I have included the source code in this
package.  Four years have passed since I've seen the game or
the source code and it took me a while to follow the code
due to the lack of comments and order.  Nonetheless maybe
it'll be useful for somebody.

-- How to start
1. Send the group file INTRUDER.83G to your calculator
2. Run INTRUDER
3. The title screen appears.  Press 2nd to begin and
   clear to quit.  During the game press Mode to start
   over.
4. Enjoy

-- How to Play --
After starting the game from the title screen,
you can move your tank back and forth with the
arrow keys.  Shooting is accomplished by pressing
the 2nd key.  You acquire one point per PI destoryed.
You are penelized no points if the PIs hit the ground.
They're dead anyway.  But watch out!  If one hits your
ship your dead and you only get 4 ships.  Good Luck!

-- The Story --
Why are you shooting PIs that are crashing to their 
death?
Once upon a time, there was a really big PI.  This PI,
one with a grudge against people who owned TI-83 
graphing calculators, decided one day to attack Earth.
At once, he sent his minion PIs that were under his 
command to crash into the planet and destroy the planet's
civilization. A scientist in Canada observed 
hundreds of PIs traveling toward Earth with certainty of 
collision.  He alerted the world and organized a
Canadian military to shoot the PIs down as they fell.
  The fellow put in charge is you!  You and your 
TI-83 calculator can save the world from the 
PI Intruders!

-- Assembling --
The source code is divided up into many files.  The main
file is intruder.asm.  This is the one you send to the
assembler.  The other files must be in the same 
directory as intruder.asm.  It assembled fine for me
using tasm.

The IBM-PC port assembles with MASM.  Because it is
less than 64k is assembled to a COM file.
