00:58:45 dik leatherdale: Since Peter Thorne is sitting in front of an image of CSIRAC, it seems opportune to say that the next edition of Resurrection has a really interesting article on CSIRAC its structure and an emulator for it by Bill Purvis. Enjoy. 01:05:20 Jerry McCarthy (TNMOC): As used by the Schumacher Rechenscheiber…., I believe. 01:30:26 Adrian Ccornforth: You describe a compact very complex system. 01:32:05 David Link: Is Ludgate's Analytical Engine more similar to Babbage's Difference Engine than to his Analytical Engine? 01:32:41 Adrian Ccornforth: You describe a compact very complex system. What are the teams thoughts on likely reliability? Babbage for example provided a mechanism to 'shake' the cogs and for halting on error 01:42:25 dik leatherdale: Is it known whether Ludgate ever made any attempt to build his design or to obtain funing for it? 01:43:51 Charles Lindsey: I see some resemblance to Aiken's built at Havard in the 1940s 01:45:41 Jim Hancock: In the 1970’s I worked with Eric Ludgate, a mechanical engineer in the magnetic tape department of ICL Kidsgrove. 01:46:28 Terry Froggatt: I wonder if he ever walked under Broome canal bridge in Dublin, and saw Hamilton's equations. 01:46:36 Rob Schofield: Thanks for the excellent lecture, very interesting! 01:55:28 Gerard Alberts: In IB Cohen's biography of Howard Aiken there is (p 70) in indirect reference to Ludgate: Aiken referring to predeceesors (Babbage, Bollée, Scheutz, and Ludgate) clearly based on the reading of Baxandall 1926. 01:56:07 Gerard Alberts: no sound 01:56:32 Gerard Alberts: no 01:58:06 Gerard Alberts: This was sbuilding upon Charlses Lindsey's remark 01:58:07 Jerry McCarthy (TNMOC): It all went brilliantly, I thought. Thanks a lot!! 01:58:16 Jonathan Bowen: Excellent, thank you! 01:58:40 Philip Wardle: Well done to Brian and the CCS for making the hybrid meeting a success - many thanks all 01:58:45 David Link: Excellent and a very nice lecture! Thank you. 01:59:08 Peter Crouch: Thanks for a very interesting presentation. 01:59:48 Nisansala Yatapanage: Thanks, Brian, for an interesting talk - great to be able to watch it from Australia. 02:00:35 Peter Radford: Fascinating!
