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.
