        Note: These brief instructions are sufficient to help you use 
               CELL SYSTEMS and get some idea of its potential. 
      For a complete and detailed set of instructions, you will need to 
    write to the above address, enclosing $15 (made out to Charles Platt). 
          This buys you the full documentation plus the most recent 
                 update of the program (if any) plus a year's 
                     question-and-answer support by mail.

CELL SYSTEMS is a program that creates beautiful patterns which also have 
mathematical significance. You can use the program merely for its 
entertainment value ... or you can delve deeper into the math theory. 

Technically, the patterns created are "linear cellular automata." They 
simulate the growth processes of simple biological entities. This program 
allows you to create new growth patterns of your own, save them, re-run them, 
and edit them, with a minimum of technical knowledge and maximum ease of use. 
The program works in high-res and medium-res modes, and the disk has a library 
of patterns already installed, with room for many more. 

To run CELL SYSTEMS you need an IBM PC, PC XT, PC AT, PCjr, or PC compatible 
with 128K memory, one disk drive, color graphics adapter, color monitor, and 
PC-DOS or MS-DOS version 2.0 or later (version 2.1 for the PCjr). 

To make a backup copy of this disk, we suggest you use the FORMAT /S command 
(described in your DOS manual) to format a blank disk with DOS installed on 
it. Then use COPY *.* to copy all the files from this disk to your new disk. 
The AUTOEXEC.BAT file will automatically start the CELL SYSTEMS program when 
you insert your copy-disk and switch on the computer. 

Alternatively, with your DOS A> prompt on the screen, type CELSYS and press 
the Enter key, to activate the program. 

The first time you use the program, it will ask you some questions about your 
system. It saves your answers on the disk, so you won't have to go through 
this process more than once. The main questions are: 
     Color. If you want to run the program on a composite monochrome monitor, 
instead of a color monitor, indicate your preference here. 
     Printer Type. If your printer is on the list, enter its number. 
Otherwise, you will have to answer a series of questions about your printer's 
graphics capabilities. If these questions are too technical, you can skip 
them. Alternatively, you can order our complete instruction manual (see above) 
which takes you step by step through the questions. 

The program itself now begins. The title screen offers you four options, 
itemized at the bottom. To sample the program's capabilities, choose option 1 
and sit back to enjoy the show. All of the cell systems stored on the disk 
will be displayed in random order. 

When you get bored, press Esc twice to interrupt the display, then answer N 
for No to all the questions. Now select option 3 from the main menu. The 
program asks you if you want to load a pattern from the library on the disk. 
Press Y for Yes. Then type the number (not the name) and press Enter. The 
pattern will now run itself for you, and stop either when it dies or at a 
predetermined cutoff point. In the latter case, you will be allowed the option 
of extending it. 

Interrupt the display as before, to get back to the main menu. Now select 
option 2. This gets you into the mathematical/creative part of the program. 
You can now edit the parameters that produced the pattern you just saw. 

You'll need our complete operating instructions for all the details, but 
here's a brief summary of the editing functions: 
     The screen is divided into four "zones." Press Enter and Esc to move the 
cursor forward and backward from one zone to the next. Press the cursor keys 
to move the cursor within the limits of each zone. 
     Inside each zone, you can change the existing values. Highlighted letters 
in the prompt-lines show you what your options are. 
     The first zone specifies fundamentals such as the number of colors and 
high-res or medium-res display. 
     The second zone allows you to specify your choice of colors. More colors 
are available in medium-res than high-res, because of limitations in the IBM 
CGA adapter. Press the initial letter of each color you want (e.g. B for 
Blue). Note that you need to press X for Black. 
     The third zone shows the initial pattern of cells in your cell system. 
Change this using the left-right cursor keys and the code-numbers assigned to 
your colors (see zone two). 
     The fourth zone shows the "growth rules" for your cell system. The 
pattern of surrounding cells will determine the color of each cell during the 
next growth cycle. The program displays all available permutations of color 
patterns, and lets you choose the new cell color that will result. Use the 
up/down cursor keys and press the code numbers of your colors. 
     Press Enter to grow your new version of the cell system. It may die, it 
may flourish, or it may fill the screen with a random mess. If the result is 
esthetically pleasing, you can add it to the library of cell systems on the 
disk.
