→ Anthony Hay has built what he believes is an implementation in C++ of ELIZA that attempts to be as close to the original as possible: https://github.com/anthay/ELIZA It was
made to closely follow Joseph Weizenbaum’s description of his program given in his January 1966 Communications of the ACM paper. It is controlled by a script identical to the
one given in the appendix to that paper. When given the prompts that begin “Men are all alike” it gives back the identical responses and recreates the exact conversation from the
[Okay, this is crazy: Cherry's version of Eliza appears in a book called "Learning Lisp", which was an imprint of the manual for an Apple ][ Lisp, written by Cherry, called PLisp. Cherry's Eliza seems mostly based upon Shrager's 1973/1977 BASIC Eliza. (It has essentially the same key and response structure as Shrager's, but has a priority system, a ittle like Cosell's. So it's not a direct translation, but is pretty close.) Shrager's Eliza had been ported to an Apple ][ at some point, so Cherry would definately have had it close to hand. Anyway, so bear with me here now: Cherry's PLisp manual was actually a port of a Lisp textbook written by Shrager and a friend (Steve Bagley) in about 1979. (See the preface to Learning Lisp). HOWEVER, Shrager and Bagley's book didn't include an Eliza !! Cherry apparently added it for either the PLisp user's manual, or later for the imprinted book version of that manual. What this means is that Cherry, probably unknowingly, borrowed (fairly directly) Shrager's BASIC Eliza, which was itself borrowed (indirectly) by Shrager from a Lisp program, back into a different Lisp program to appear in a manual/book on Lisp originally co-authored by Shrager, who wrote the original (BASIC) Eliza that Cherry based his Lisp Eliza on ... Confusing enough for you!?]
→ This amazing Eliza in gnuCOBOL was written by Arnold J. Trembley. It's a slightly indirect translation of Shrager's 1973/1977 BASIC version. The most amazing part of this (to
me) is that it was written in 2017! Mr. Trembley's web site contains links to gnuCOBOL compilers and other fun stuff.
