Tennis is one of those simple but addictive games
for two players with each using a joystick. The aim is simply to
return your opponent's shots by moving your player with the
joystick. You gain a point each time your opponent misses and the
first player to reach seven points is the winner. Pressing START
begins a game and player 1 serves first. Thereafter service goes
with the points. The fire button serves the ball.
TYPING IT IN
The program is a machine code file which is
created on tape or disk by the Basic program listed here. Type in
the program, using TYPO 3 to check it as you type, and then save it
to disk or tape in the normal way.
If you are using a disk drive you will need a
formatted disk with DOS written to it in Drive A. Run the Basic
program and choose option 1. An autoboot listing will be created on
your disk and the game can be run by simply re-booting.
If using cassette, load the original program and
place a new tape in your cassette. Press PLAY and RECORD and then
RUN the program. Choose option '0 and the machine code program will
be written to your tape. You can now rewind the tape, switch off the
computer and run the game by switching on with the OPTION and START
keys held down. Press PLAY on the recorder and RETURN and the game
will load and run automatically.
