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.

news
May 25th, 2013: New Home
In conjunction with the
relaunch of the Konrad Zuse Internet Archive, the ENIAC Simulation
moved to a new URL at http://zuse-z1.zib.de/simulations/eniac.
Further, the project now can be found on
github. Some bugs are fixed as well.
February 14th, 2006: ENIAC simulation at
the University of Pennsylvania
For the ENIAC's 60th anniversary, due to Jan van der Spiegel,
the simulation is installed at the UPenn's website, too.
February 11th, 2006: A Java Simulator for the
ENIAC
An
article about the simulation, written by Raúl Rojas
and Till Zoppke, is online.
May 24th, 2005: Slides online
The
slides of a talk about the simulation at FU Berlin are online
(German language only).
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.
