Today I went to The National Museum of Computing at Bletchley Park for the Members' Club Open Day. The museum is currently constructing a full-size and, as far as possible, historically accurate replica of EDSAC. This is now nearing completion and will hopefully be fully operational sometime next year. I was able to talk to some of the people who are working on the project about it and also about my somewhat less historically accurate version. Later, with the assistance of TNMOC volunteer guide Peter Hoath, I was able to get this picture:

Yes, it's an EDSAC in an EDSAC. This is my EDSAC simulator sitting in one of the racks of TNMOC's full-sized rebuild.

My thanks to the staff and volunteers of TNMOC for allowing this, and to the members' club committee for organising the open day. If you ever get the chance to visit the museum I would highly recommend it. If you do go and enjoy it, you might want to consider supporting the museum by joining the members' club.
