                   Space Flight Simulator
                        version 1.01
                  (PC-Compatible Binaries)

                     ------------------

Bywater Software is pleased to announce the public availability
of its Space Flight Simulator in its first complete release, 
version 1.01.  This software is copyright (c) 1991, Ted A. 
Campbell, and is released under the terms of an agreement specified
in the file "sfs.ro".  

Description:	The Space Flight Simulator offers a graphics-based,
		real-time, animated simulation of orbital flight.  
		Users can develop simulations by specifying a complete
		range of orbital parameters, and can develop simulations
		for all of the planets of the solar system and for some
		other celestial bodies.  A particularly full map is
		given of the earth, which can be viewed as it would
		appear from the orbiting spacecraft, as a ground-track
		map, or as a "distant perspective" in which the earth
		(or another orbital focus) and the orbital track can
		be seen together.

Requirements:	This implementation of the Space Flight Simulator
		requires an IBM PC or compatible microcomputer,
		with Hercules, EGA, or VGA graphics.  The optional
		use of a pointer device (mouse) is supported. A
		fast cpu and a math coprocessor will also speed up
		and smooth out the overall display. The program 
		requires one disk drive that has at least 700k
		of space available. 

Documentation:	Complete documentation for this program is in the
		file "sfs.ro", which is in a format compatible 
		with the "ro" text formatter (also supplied).

Source Code:	This release of the Space Flight Simulator will
		include source code for the complete Space Flight
		Simulator, and its underlying User Interface (ui).
		The source code can be compiled on the PC-compatible
		microcomputers, the AT&T Unix PC, and on Unix
		Platforms which have implemented the X Windows
		system, version 11 (tested on DecStation 2100 and
		3100).
