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.”
