There were many implementations of IPL-V. According to the manual (https://bitsavers.org/pdf/rand/ipl/Information_Processing_La...) 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"). Thanks!
- There are references to the IBM 7090/7094 version under IBSYS online.
In this 7094 emulator package on Github: https://github.com/Bertoid1311/B7094 (in the zipped distribution files unfortunately) I think there is a copy that is runnable? see: Docs/Bamberger-MAMOS_docs/BAMBSYSLB1_patch_for_IPLV.txt
It describes patching the available binary to make it work, with the caveat that it's unclear if the interpreter is correct/intact (but it does run the demo programs).

- Why do you need the old code if you implement your own interpreter anyway? Why "(ironically) Lisp"?
