Think an Apple II is retro? Try programming ENIAC | ENIAC - The first general-purpose electronic computer
This web site is devoted to ENIAC — “Electronic Numerical Integrator And Computer”. ENIAC was the first general-purpose electronic computer. It was made at the University of Pennsylvania’s Moore School of Electrical Engineering during World War II under the code name "Project PX". Physics professor John W. Mauchly and electrical engineer J. Presper Eckert led the team. Both were civilian employees whose computer work was funded by the United States Army Ballistics Research Laboratory. This is a collection of the best online information about the ENIAC and the people that created it.

Think an Apple II is retro? Try programming ENIAC

This desktop ENIAC simulator lets you learn about the ENIAC the way any respectable hacker does – by monkeying with it.

Our favorite 30 ton computer is turning 65 and not looking great for its age.  But although the original is currently chopped into pieces and scattered across the world like Voldemort’s horcruxes, clinic there is a working ENIAC.  It is a java applet that you can download and play with here.

The desktop version of ENIAC is by Till Zoppke, view who says he was inspired by the ENIAC-on-a-chip that was built at Penn.    It is pretty impressive; you can move patchcords, set switches, and watch it go through it’s paces on a couple of sample programs.  Try to break it, it’s only fair.  There are some tutorials posted there too, for when you get stuck.

An article about the simulation, written by Raúl Rojas and Till Zoppke, is available there, called The Virtual Life of ENIAC.” It is all hosted by our friends over at at Konrad Zuse Internet Archive.

    I downloaded the desktop Eniac and then some guy from Sperry told me it had already been done.
