> Since Lisps stand over heavy usage of list data structures, it is only natural that someone would want fine-tuned hardware to deal with those, so these machines carefully reduced execution costs with specific hardware, CPU instructions, and specific memory management.

Kind of, classical Lisp as it was born, yes.

The Lisp Machines variant, as well as Common Lisp, provide all the features of regular programming languages, structures, arrays, stack allocation.
