I know the keyboard diagrams on my web site (the domain name expired, I've fixed that, but wait a day before visiting, as it may not have propagated to your area) were made to look like old-style keyboards, rather than the style the IBM PC introduced. I did not now they have a technical term for them now - SA Profile for stepped (which is what my diagrams use for simplicity) and DSA Profile for sculpted. (Oops; at least according to the Signature Plastics web site, it's the other way around.)
I am glad to have learned this, now I can find such keycaps for sale, and find more information.
