This was very interesting, thank you. The original Mac keyboard you'd linked to is exactly what I would've expected from Apple. You're right about the control key. IIRC back in the day it was used to actually activate "control" characters that instructed the computer to do something (I suppose roughly equivalent to the Fn key today). It's a bummer that folks started mapping it to other things and it stayed on, vs. being merged with the Alt/Option key.
