              POWER/SPEED CALCULATOR FACT SHEET

Description
-----------
PSCalc is a computer program designed for the automobile professional
or enthusiast to help analyze various engine and drivetrain needs for
optimum performance.

PSCalc is shareware, uncrippled, and free to try out.  Share it with
your friends!  The latest version can be acquired on the internet at
 	 http://users.vei.net/pscalc/software.htm
or can be downloaded from River Canyon BBS at 423-886-2521.  Search
for text of 'PSCalc' or file 'PSC*.zip' in the new files directory.

Requirements
------------
PSCalc runs on IBM PC Compatibles with DOS 3.2 or higher, or Windows
3.x, Windows 9x, Windows 200x, or Windows NT.  Any processor from an
8088 to a Pentium with 512k or more of memory.

If want a graphical interface & have more power under your computers
hood, you can order PS:Calc for Windows!  See the file REGISTER.TXT.
