Do you have a Babbage Difference Engine in dire need of servicing? Fret no more! Reg Crick of the London Science Museum has put together this handy "INSTRUCTION MANUAL to Operate and Maintain Charles Babbage's 2nd Difference Engine," written in 1991 to help keep the Engine built at the museum (to mark the bicentennial of Babbage's birth) in tip-top calculating condition.
