The simulator is written in JAVA and requires a system with a Java interpreter and a display resolution of at least 800x600. A Java runtime environment (JRE) of at least version 1.1.7 is required. Simulation executes at about 1/10 real-time on a Pentium-II, 400MHz system. On the slowest Pentium, it would be about 1/100 real-time, which should be acceptable. Java requires a 32 bit operating system, and won't run under Windows 3.x or MS/DOS.
Download the JRE from Sun's web site, the Windows version on this CD (if supplied) or where available for your operating system.
Unzip the simulator into the folder (directory) you will be using. Run the simulator with the command line:
jre -cp SimHC12.jar SimHC12
Using "My Computer" or the Explorer, you can also (right mouse button) drag Simhc11.bat from the folder to the desktop, saying you want a shortcut. Then you can click on the icon to run the simulator.
The simulator can also be started with several command line options.
