[Feature Request] Support for legacy Lisp machine emulator and custom OS interfaces

Bug Description
I am trying to get a the runtime for a realtime OS running on a lisp machine emulator. The runtime assume Ivory hardware and so claude needs to update to use the emailulor and OS support interface. It accesses the runtime over the network and is trying to get it too boot, but fable 5 guadrails keep firing. Opus 4.8 is probably not up to the task. I am a member of the CVP program, which does not seem to be doing me any good. Great if you can fix this instead of slowing down progress.
