This software has been put into public domain.
The binary was compiled using Turbo Pascal 7.0 compiler. The fix for the infamous division-by-zero error was applied after being downloaded from here. On the same page, you will also find another copy of Turbo Pascal 7.0 compiler.
The binary was compiled without 80286 instructions, without debug symbols, and with numeric processing emulation. It needs at least EGA graphic adapter. Neither audio output nor printing did work in a Windows XP VM on VirtualBox.
