I had a meeting at the University of Manchester computing department last week and I took the opportunity to visit their 'computer museum' which is spread out across the Kilburn building, there are some fine exhibits in there.
I took photos on my phone but they aren't great but I did find it facinating particularly the Atlas built in conjunction with Ferranti. In 1962 it had 48bit word size and 24 million word address bus!
https://en.wikipedia.org/wiki/Atlas_%28computer%29There were also parts of 'Baby' which was built in 1948
https://en.wikipedia.org/wiki/Manchester_Small-Scale_Experimental_MachineI've attached a few photos of the Atlas ROM. For an idea of scale this is a 2 metre high cabinet.
I hope I'm not breaking some post rule attaching the photos.
Regards,
Chris
