There are references to the IBM 7090/7094 version under IBSYS online. In this 7094 emulator package on Github: https://github.com/Bertoid1311/B7094 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).
