Gravitational NBody Simulation for Windows NT Alpha
Version 1.8 (April 1995)
written by Henley Quadling (hquadling@mnhep.hep.umn.edu)

This update contains the Alpha AXP binaries.

nbodya.exe       Alpha AXP version

New features in this version:

1. There is a new Rotating Frame option. This option uses a reference
   frame centered at the center-of-mass of the system, and rotates with the
   same angular velocity of a body that you choose. For a demo of the 
   usefulness of this option, try the following:

   a. Start demo9 (using the load and run option in the file menu)
   b. Select 'rotating frame' using the second combobox on the toolbar.
   c. Click on the red planet circling the center star. 
   d. Speed the simulation up if necessary.

   The red planet is Jupiter, the two other bodies are 'trojan' asteroids 
   approximately 60 degrees away from Jupiter.

   This version loads and saves v1.7 nbd files, so the rotating frame
   options cannot be saved in this version.
