Sorry, I shortened to the point of inaccuracy - I should have said not fully electronic _speed_. Not meant to say that it was mechanically reading and writing values per se, just that the slow rotation of a mechanical drum was essential for its operation and ultimately had a limiting effect on the speeds it could compute. Thus the electronic storage and compute was rather defeated by inclusion of a mechanical element in the “critical path”, so to speak. I think that’s accurate to say?
