About the seminar

Andrew Herbert, Project Manager for the EDSAC Replica Project will give an update on progress with the project.

Much of the rest of the machine is now reasonably well-understood and under design including the arithmetic functions ("computer control"), instruction fetch and decode ("main control"), computer-store "coincidence", input/output and initial instructions.

There is good progress with the nickel delay line store, with short delay lines now working quite reliably.

On the programming side we have re-created Wheeler's "coordinating orders" which will allow us to run both the first EDSAC programs (squares and primes) as well as later programs using the extensive EDSAC subroutine library.
