- These programs require an IBMPC or clone with a CGA card. A monchrome monitor
- will give shades of green (quite acceptable). You don't need much memory and
- everything will work with one floppy drive.
-
- If you don't know what the Mandelbrot set is, I recommend an article in
- Scientific American, August 1985, by A.K. Drewdney.
-
- You should find the following files in this ARC'ed file.
-
- MANSET.COM
- MANSET87.COM
- MANSET.PAS
- QUIKPLOT.COM
- QUIKPLOT.PAS
-
- and some *.PIC files.
-
- To generate pictures from scratch you should either compile and run MANSET.PAS
- (which requires TURBO PASCAL) or just run MANSET or MANSET87 from DOS. To get
- an idea of what to expect, try QUIKPLOT first and look at some of the *.PIC
- files I have included.
-
- As you might expect, MANSET87 requires the presence of an 8087 co-processsor
- chip, but it is MUCH faster. Be prepared for overnight runs if you have a
- standard PC or clone with just an 8088.
-
- When the program starts, it will ask for a picture name (any 8 character DOS
- filename will do, but I recommend you keep it shorter as you will find out
- there isn't room for 8 characters on the screen. The examples use P01 etc.
-
- You will then be asked for :
- Real corner (Top left on screen)
- Imaginary corner (Also top left)
- Side
-
- Try Real = -1.25, Imaginary = -1.25, Side = 2.5 at first. This will display
- the entire Mandelbrot set and its surroundings. After that you can zoom in
- and find out what all the fuss is about. Remember that there is nothing of
- interest in the set itself (the central black area) but in the areas close
- by.
-
- The picture you generate will be stored in a *.PIC file, which can be
- redisplayed by using QUIKPLOT. This allows you to build up a library of images.
