Seeking an IPL-V Interpreter
(Part of) the team who recently reanimated the original ELIZA (https://news.ycombinator.com/item?id=42746506) is now working to reanimate what are often considered the first AIs -- the symbolic heuristic programs built by Newell and co at RAND in the 1950. Most of these programs were written in IPL-V, the fascinating (if ugly) machine level language for a stack machine that was the first to introduce list processing, recursion, and symbolic computing, among other innovations that we take for granted today.There were many implementations of IPL-V. According to the manual (https://bitsavers.org/pdf/rand/ipl/Information_Processing_Language-V_Second_Edition_1964.pdf) implementations existed for at least these machines: B220, CDC 1604 and G-20, Ferranti Mercury, IBM 650, 704, 709-7090, 1620, Philco 2000, UNIVAC 1105 and 1107, and the AN/FSQ-32 (whatever that was). And we know that it was also on the IBM 360 and 7094.If you have access to a code archive for any of these machines, and can search it for the IPL-V interpreter, we would greatly appreciate it. (A print out is fine -- preferred in fact!) We are building one ourselves in (ironically) Lisp, but it would be amazing to be able to run an original stack, as we did with the 7094->CTSS->MAD stack in reanimating ELIZA.We (obviously) open source everything we do.You can post here, or DM me (my email is in my "HN about").
