If so, it should look somewhat similar to inferior-lisp-mode.
Or probably even use define-derived-mode directly.

Go read the Elisp manual, especially the part that talks about the coding
conventions to use for a major mode. A major mode should *not* start
a process or do a switch-to-buffer.
You want to define another function, like `run-nyquist' which may do things
like `run-lisp' or `switch-to-buffer' (though I'd recommend against using
that and advise to use pop-to-buffer instead) and which will use
`nyquist-mode', defined with define-derived-mode.
