Goal Keeper

In 1989, a 13 years old boy wrote a game at his computer extracurricular classes. It was written in GW-BASIC, using nothing else than ASCII characters. Now, in order to publish it, the BASIC source has been slightly revised. Sound has been added and also the keyboard input has been improved. It has been compiled using Borland's Turbo BASIC 1.0, as it is greatly compatible with GW-BASIC, with the advantage that compiled code which is way faster than interpreted code.

Requirements:

MS-DOS/PC-DOS 2.0 or higher
8088, 8086 or higher processor
Any card capable of displaying 80 columns text (on the IBM PC world, just anyone)
Enough RAM to host the operating system plus a 33 Kb executable
