"The Best Freeware/Shareware Program of 1995 is

- American Astrology, March 1996
"One exceptionally good freeware program is available
to astrologers -
good enough to be worthy of review with the main commercial programs.
This is Astrolog..." - The Mountain Astrologer, November 1995
"For a free program to have such a superb ephemeris

Astrolog system requirements:
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
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.
For Unix systems, some C compiler is required since
ready to run
executables aren't available. Astrolog can take advantage of X11
Windows but they are not required.
Astrolog will compile and work on VMS systems, even
with X Windows,
but this isn't officially tested. A .COM makefile script is included.
On the Macintosh Astrolog will compile and run with
including some interactive graphics, using for example the Symantec
C/C++ 7.0 compiler for the Mac. It will run on any reasonably recent
68K Mac with 750K free, and will run on PowerMac's in emulation mode.
A few third party ports of Astrolog are publicly available.
includes a port of Astrolog version 4.00 to OS/2 Presentation Manager
by David Serls, a port of Astrolog 2.25 to the Macintosh but with
interactive graphics by Pascal Lamboley, and a port to the Amiga by
Where to get Astrolog:
Astrolog's homepage at http://www.magitech.com/~cruiser1/astrolog.htm
which allows downloads using a Web interface of all the Astrolog
files at the Magitech FTP site below. This site also offers
information on the program, current bug lists, screen shots, and
links to related sites.
Astrolog's own Web domain at http://www.astrolog.org,
where the page
http://www.astrolog.org/astrolog.htm is a mirror of the site above.
If one site ever happens to be down, the other site should work.
The anonymous FTP site ftp.magitech.com (or magitech.tcastle.is.net),
maintained by J.H. Trott. The directory /pub/astrology/astrolog
contains all executables, documentation, and source code, for DOS,
Windows, Unix, and the Mac. All ephemeris files are available in the
The anonymous FTP site ftp.coast.net (and its mirrors
oak.oakland.edu). These are SimTel sites where the PC Astrolog files
may be found in /SimTel/msdos/entertn in the file ast54dos.zip, and
in /SimTel/win3/entertn in the files ast54win.zip and ast54src.zip.
The BBS "Astro Net-1" at US phone number 414-481-9976,
Carl Baewer. This is for PC's only, but has all DOS and Windows
executables, source, documentation, and ephemeris files. They do want
one to register first, but that and downloads are free minus any long
Several past versions of Astrolog have been posted to
newsgroup comp.sources.misc and hence are available at many other FTP
sites archiving this group. Utilities such as archie can locate these
sites, such as ftp.uu.net. The latest Astrolog release for which this
was done is 4.10, in volume 32. (Older versions are in volumes 37,
30, and 28.) Note that those releases are only in Unix shell archive
format and have no binary files in them.
Right after a new release, the files for Astrolog may
found on the Usenet newsgroup alt.astrology, while the Unix source
can sometimes be found on comp.sources.misc if the version in
question was submitted there, until the articles expire.
Note that the following anonymous FTP sites used to
files but don't anymore: hilbert.maths.utas.edu.au, maintained by
Michael Bulmer, and ftp.u.washington.edu.
When accessing sites offering Astrolog, one may encounter
files. Here is a list of them and what they contain, so one will know
which ones to actually download.
A summary of Astrolog and what it offers. What you're reading now.
A copy of this file is contained in ast54win.zip, ast54dos.zip,
ast54src.zip, ast54mac.hqx, and ast54unx.shr.
A ready to run MS Windows executable and related files. For most
users, this is the only file needed. Pkunzip version 2.04 or later
required to unpack.
A ready to run DOS executable and related files. For most PC users,
this is the only file needed. Pkunzip version 2.04 or later is
required to unpack.
The source code. Requires a C compiler to use and pkunzip again to
unpack. Not required to run if you already have the executable above.
A ready to run Macintosh executable and related files. This is just
like ast54dos.zip but for the Mac. BinHex 4.0 is required to unpack.
The source code and other useful files to run. Contains all of the
files in ast54src.zip, but in Unix shell archive format. Requires the
Bourne shell command sh or equivalent utility to unpack.

this file is contained in ast54win.zip, ast54dos.zip, ast54mac.hqx,

if one is familiar with and upgrading from the previous version. A
copy of this file is contained in ast54dos.zip and ast54unx.shr.
Describes the history and additions made to each version of Astrolog
since its beginning. Generally only useful if one is upgrading from
several versions ago and wants to be updated on the past few releases.
LRZ5_xx, CHI_xx, CPJV_xx -
Ephemeris files. Not required but provide more accurate positions.
The files are in groups with xx being a number indicating the time
period covered. The three files LRZ5_24, CHI_24, and CPJV_24 cover
the current and 21st centuries. A copy of those three files are
contained in ast54win.zip, ast54dos.zip, and ast54mac.hqx.
