This walkaround experience of the Science Museum might be of interest: I've started you off in front of the Soviet BESM machine - round the back of it is a CDC 6600. There's a bunch of micros in a display to your left, and the Pilot ACE just beyond that.
Beyond the CDC 6600, between a Xerox Alto and a MITS Altair is Englebart's mouse. Lots more too, of course.
