"Mechanically" is funnier expression. But kinda true because it switched also trunk lines in some small PBX. 8080 was bloody expensive in 1976 and RAMs were too. I only heard about because I was employed to design something similar for Telenokia.
Low effort humour is discouraged, it's in the site guidelines and since it wasn't amusing, just confusing, perhaps you should skip the humour and consult them.
