ENIAC simulation: index

welcome

This page is the home of the ENIAC simulation. The ENIAC was the first electronic digital universal computer built at Pennsylvania University in 1944-1946. The ENIAC simulation is a Java-Applet simulating the ENIAC with a 2d graphical interface, implemented 2003/2004 at Free University of Berlin.

If you visit this page the first time, you probably want to start the simulation. You also can read a few lines about the ENIAC's history. If you face any problems in starting or handling the simulation, please refer to the f.a.q. A collection of other websites related to the history of computing you can find in the links section. There also is a page about this project and its contributors.

May 10th, 2005: Euklid's algorithm
A new configuration example, an implementation of Euklid's algorithm, is wired. Further, a few bugs are fixed, and the ENIAC simulation is now available as applet, by Java-Webstart and for download.

November 1st, 2004: Site goes online
The ENIAC-simulation, the diploma thesis and some additional information are accessible online.

June 2nd, 2004: First version complete
The first version of the ENIAC simulation is working. The Initiating Unit, the Cycling Unit, the Accumulator Unit and the Constant Transmitters 1 & 2 are simulated. Loading and saving of configurations (that means ENIAC-wirings) is supported. Beside empty configurations, a simple addition-example and a configuration for computing Fibonacci numbers are available.
