General Description
-------------------

This is a 2000 baud BASIC program for use with a Bally Astrocade and Astrobasic.


Alternate Version Descriptions
------------------------------

Paul Thacker investigated the six different versions of Astro Zap 2000 and discovered these differences:

These programs are noticeably different, though sometimes in buggy ways.  Four of these alternate versions are from Brett Bilbrey, who was in a Bally user group with George Moses.  It's possible these are beta versions of the program from George himself. 

Regular (non-alternate) Version - Probably the official version.  It's the only version with that uses the knob to select the number of players, and isn't missing any features that other versions have.  The title screen dates it 9-28-82.

(a1) - From Brett, and plays like the standard version (from Mike White), but it has a simpler player select screen.

(a2) - Nearly the same as alternate 1, but the player select screen is blue instead of black.

(a3) - Alternate 3 is about like alternate 2, but some of the gameplay graphics are drawn on the title screen.  Also, the ships that fly in circles around your base seem to appear more often.  This one was dated 7-25-81 by Adam back when he recorded it.  I assume this was on the tape or something.

(a4) - This version has a different title screen and different sound effects.  I don't think there are any circle-flying ships in this version.

(a5) - This version is unstable, crashing with an error in line 100 after playing for a little while.
