Model T

The Model T was an automobile produced by the Ford Motor Company on Earth. The Model T was later improved upon, creating the Model A.

When he ended up being the controls of the USS Enterprise (NCC-1701) in 2270 after being in 2020 merely days before, Shaun Christopher felt as if he were a Model T driver who suddenly ended up in a hovercar. 

When Berlinghoff Rasmussen compared him to the Model T, Data said a Model A might be a better analogy as Data was an improved prototype.
