WELCOME
To The Exciting World of CATF
(Computer Aided Tropical Fish)
Your CATF kit includes five ASKEY tropical fish, a complete
filtration system, and an automatated hatchery/feeder for
SMILEYFACE SHRIMPS. All you need to add is a container (a
computer monitor will do very well).
Until recent developments in computer technology ASKEY fish
were very difficult to maintain. They must be fed live food every
few minutes and they need pure "O" and "o" type air. The
SMILEYFACE SHRIMPS which are fed to the fish are well known for
their optimism even in the face of death, and will keep your fish
healthy and happy for a long time.
Setup instructions:
At the DOS prompt "A>" type the following: CATF (Return)
Operation and Maintenance: None required
Leaving the program:
If you need to leave the program to use the computer for
some other task, simply press the ESC key to return to the real
world which starts at the DOS prompt.
Program History:
Some time ago I was writing a letter using electronic mail
to someone who received a lot of electronic mail. I decided that
if my letter was to be noticed I would have to do something
original. The result was a fishbowl scene using all ASCII
characters which would could be printed on a non-graphics
printer.
Later on, I decided that I would try to animate the picture
in a program.
The program is written in assembly language using a pseudo
random number generator to control the movements of the fish and
food. I added a few non-printer characters and color to the
picture (the non-printer characters are the smileyfaces and the
matte character to fill in the fish).
