It looks like the computers on The Enterprise look similar to computers of the time period it was filmed. The displays, the controls, and the weird noise it makes. Does anybody know why it makes this noise? As the computer talks, She also makes a rattling noise similar to a very loud mechanical hard drive. Computers of the 1960s had memory that was also mechanical. I would assume that it would also be loud and that is why the Enterprise computer makes so much noise. Is this supposed to be Drum Memory? Is Drum Memory Noisy? Did it make loud "hard drive" noises even though it was memory? Does anybody remember old computers of the 1960s and compare them with the Enterprise from TOS?
