A substantial account of the project to rediscover and emulate LEO III programming software. Under the heading Software in the Society Activity section two other items are reported by Holdsworth: LEO III Rescue, leo.settle.dtdns.net/LeoCode/impasse.htm. and LEO III Documentation, leo.settle.dtdns.net/LeoMan/LeoMR.htm The whole issue can be downloaded from http://www.computerconservationsociety.org/resurrection/res70.htm#e
David notes “All of a sudden, it works”, pp.8-9. http://www.computerconservationsociety.org/resurrection/res71.htm

David has commented:“…it looks a lot like a real Leo, or so I am told by people who knew the real thing. What is more important than the replica is the software that we have, namely the Intercode Translator, the Master Routine and its accompanying generator programme. All three run successfully on our replica. There may be the odd malfunction, but that was common in computing in the 1960s.”

I have been co-operating with Leo Society members in updating their LEOPEDIA, and it now contains links to our stuff both on sw.ccs.bcs.org and Resurrection. I am looking for information on early assembly language programming, in an attempt to comprehend the state-of-the-art at the time that Intercode was designed. My amazement at Intercode is documented in Blow By Blow. It may be that I was not properly aware of the programming conventions of an era that slightly pre-dates my own entry into the world of computing, Resurrection,

Holdsworth reports that previous errors in LEOPEDIA links to his work have been corrected as well as reporting on the latest developments on the LEO III emulator and the availability of LEO III demo packages at settle.ddns.net/LeoIIIdemo3.zip Resurrectiononline at http://www.computerconservationsociety.org/resurrection/res89.htm
Holdsworth, D., (2020), Software LEO III in Leatherdale, Resurrection, Issue 91, Autumn. Pages 6 – 7. Reports on the trial by Ray Smith and Ken Kemp of their kit for running INTERCODE on Windows computer. The trial involved sending an invitation to LCS ex- programmer members to experiment in using the kit. The report by Ray Smith is summarised, and future actions proposed. The outcome was disappointing in the very small number of members who completed the trial. A larger number were prevented from completing the trial due to an inability to download the zipfiles comprising the kit. A start has been made by David Holdsworth in rationalising the LEO III presence on the new TNMoC server. The LEO III emulation facilities are operational and can be accessed via https://www.computerconservationsociety.org/emu/leo3/index.htm
