GNU Emacs is a Lisp implementation with an abstraction layer over the hardware and OS. I would like to reserve "Lisp Machine" to computers with an actual Lisp operating system or emulations of those.
Of course. I understand that calling Emacs "a Lisp Machine" is quite a stretch, but due to the lack of any actual prominent hardware-based Lisp machines these days, I think it is a permissible simplification for the orange-site discussions. Yet it is, indeed, an important clarification, I appreciate it.
These are interesting from historical educational point of interest, but they rather don't have practical use for modern software development, do they?
