On target at almost one-third of the way through, the EDSAC reconstruction project volunteers meet at the University of Cambridge, where the original EDSAC was built, to discuss progress.

Peter Linington talks on video about the original EDSAC mercury delay line store and the substitute nickel delay line store he has prototyped for the EDSAC reconstruction.

Video of the centenary celebrations of the late Sir Maurice Wilkes and the first working parts of the EDSAC reconstruction revealed.

Bill Purvis has been working on the printer for the EDSAC Replica Project. The original printer for EDSAC was a modified Creed, model 7. The one being used in the replica Project is a slightly later model (7E).

In recreating the EDSAC computer, a surprising amount of mechanical engineering is required. EDSAC engineering was originally done by hand, but for the EDSAC Replica Project modern Computer Aided Design is being deployed.

In January 2013 the EDSAC Replica Project trustees management committee met at Teversham Engineering where they saw the first replica chassis come off the production facility. They also spoke to camera about their reasons for supporting the project.

This week sees the production of the first replica components for the recreation of EDSAC, the computer that 63 years ago made general purpose computing available to users for the first time.

EDSAC was essentially modular and consisted of 12 vertical racks, each holding up to 14 individual horizontal chassis. Only three original chassis have survived, so new ones have had to be commissioned.
