It's a shame the film drives are just out of shot in that Lucas photo (I assume they're on the end of the machine; I have a feeling that was standard Elliott config) He said that the building itself in which the machine was housed was pretty large - several floors - and was pretty run-down and dirty... The Science Museum also have a surviving 803 which I think was operational until it was dismantled for storage a while back - that one's a larger config and has three film drives plus controller (we only have the one drive, and are sadly missing the controlling logic). I have a vague memory that there's another 803 somewhere in the UK in private hands (but what state it's in I'm not sure) Hmm... forgot to ask that. I'll do so though. I'm not sure whether he ever worked with anything other than the 803 machines, though (but presumably would remember a Lucas 402 if it was ever there whilst he was visiting the site). I know we've got some 401 docs at the museum, but I'm not sure if we've ever come across any 402. Doesn't ring any bells with me, anyway. cheers Jules
