• For PC's, 640K of RAM and a reasonably recent version of DOS. A math co-processor chip is recommended for best performance but not required. Astrolog can take advantage of Ansi text, CGA, EGA, VGA, and SVGA graphics but they are not required. The program will run on 8088 AT and XT systems and higher x86 processors. The DOS version of Astrolog may be run from MS Windows in a DOS box.
• For compiling the source code for PC's, the Microsoft C compiler version C6 or later, or Borland Turbo C/C++ compiler version 3.0 or later. Other compilers should work although one will probably have to compile out the screen graphics sections.
• For the Windows version, at least 2M of RAM and Windows 3.1 or later. Astrolog for Windows will run under Windows for Workgroups, Windows'95, and Windows NT. For compiling the Windows version, Microsoft Visual C version 1.5 or later is recommended, although most any Windows compiler should work provided it can compile resource files.
