Pretty sure the https://en.wikipedia.org/wiki/IBM_704 https://en.wikipedia.org/wiki/IBM_704 was the first Lisp machine (as CAR, CDR come from register names on the 704...)
But DEC did rule academic computing well into the 80s.
- gumby 6y agoYes, I believe it was the first machine Lisp ran on though that was before my time. But the PDP-6 was a different class of device as every machine word was (could store) a cons; the common list manipulation functions (not just car and cdr but rplaca et al) were actual machine instructions etc (even if the names were different, e.g. CAR was HLRZ, as I can still remember). In other words, lisp was implemented _on_ the IBM machine while the design of the 6/10 architecture was influenced by the needs of lisp. Both Marvin and Gordon independently confirmed this to me.
