Ballooning is supposed to be a peaceful, relaxing hobby. Unfortunately, things have gone very wrong. You have to guide your balloon through sixteen difficult screens, negotiating mountains, avoiding aircraft and dodging birds. The game can be played either with a joystick or the keyboard.
How to type the programs in Balloon is a Basic program which uses machine code subroutines. These are loaded into the computers memory by the Basic program (Listing 1). This is done by line 10. It is necessary for the machine code routine to be saved either on the same disc or on the tape after the Basic program. Since not everyone has an assembler, the second program (Listing 2) is also in Basic. This program creates the machine code you will need to go with Listing 1. If you are using a disc based system you will need to type in the first listing, save it and then reset the computer. Type in the second listing and save it. Then run the second listing. This will create a third (machine code) program on the disc called 'magcode.bin'. Finally, run Listing 1 which will load in magcode.bin and use it.
Tape users will find life a little more complicated. It is easiest to use two tapes. Save the programs to separate tapes. Wind Listing 1 to the end of the program and then swap the tapes. Load Listing 2. Swap the tapes again. You should now have the tape with the Listing 1 on it in the cassette deck wound on to a blank area. In memory you should have the program for Listing 2. Type RUN. If you have not made any mistakes typing in the listing, the Basic program will save a machine machine code program for you. Once this has finished rewind the tape, reset the computer and then type RUN ".
