Dik Leatherdale has never got over the sense of wonder he experienced when he discovered computer programming in 1966 - the wonder that such things were possible. Now retired, he continues his obsession by editing Resurrection the bulletin of the Computer Conservation Society.

During the winter of 2004/5, during a period of "professional inactivity", I started work on an emulator for the first computer I ever had at my disposal (albeit only occasionally) - the Ferranti Atlas 1. It's still not finished.

I've been working on the emulator in fits and starts ever since. The difficulties of the unstandardised floating point operations are still something of a mystery and I've still got a few more extracodes to implement though the current focus is on implementing job descriptions and job scheduling. On the other hand, with the help of Iain MacCallum and Bill Purvis, we now have a working copy of the Brooker-Morris Compiler Compiler which we hope to exercise to a rather greater than non-trivial extent during 2016.
