POST MANIA
----------
by Bret Richdale
from Computer & Video Games, January 1985

Runs on ZX Spectrum in 48K

There are several things to note when typing Post Mania into your Spectrum.

First, the machine code routine at address 63000 which scrolls one line of
the display to the right or left. This is used in the program to move the
conveyor belts. Because of this routine, the game should be saved before it
is run as an error in the data (lines 8020, 8030) could cause the program to
crash.

Second, the graphics in Post Mania are not done in the standard way - instead
the character set is redefined and the computer is then told to use the
alternative set by poking the system variable 'CHARS' at address 23607-23608.
This means that all the characters in the print lines in the listing should
be typed in normally.

Line 0 should be ignored in the listing as the computer will not accept it.
It is there for copyright reasons and is not necessary to run the game.
