Here is some information from a Cambridge resident. Use it as you will.
Don't even think of driving anywhere near Cambridge city centre, unless you either know it or are a complete masochist. Taxis are available but expensive and have to be requested. Bus timetables are here: http://www.cambridgeshire.gov.uk/site/custom_scripts/bus_timetable_by_service.aspx A rather bad bus map is here: http://www.cambridgeshire.gov.uk/downloads/file/28/cambridge_city_bus_map If the map is correct (not certain, but likely!), to get to the Centre for Computing History from the centre, take a Citi 3 to Cherry Hinton or Fulbourn and get off just after a hump-backed railway bridge. It's not a nice walk. All of the Citi 4, Uni 4 and Madingley Road Park and Ride will get you from vaguely near St Catherine's to the William Gates Building, but you will need to find out where the stops are. Or it's a half hour fairly pleasant walk - I would recommend along King's Parade, through Senate House Passage, Garret Hostel Lane, Adams Road and the Coton footpath, onto Clerk Maxwell Road and turn left into the West Cambridge site. The only reasonable way of getting from the William Gates to Murray Edwards College (New Hall, as it used to be and is on the bus map) is walking. From there to the centre is a 25 minute walk. The Regal is near the centre. Regards, Nick Maclaren.
