@zarfeblong At VCF East 8.0 (2012) I hacked the RT-11 z-machine to run on Dave McGuire's PDP-11/70 and ran a cable over to my exhibit on Interactive Fiction.
@zarfeblong I've also compiled the PDP-11 code and run it on RT-11.
It does take a 1-2 line mod to run on the RT-11 runtime for RSTS/E (very minor tweak to the memory allocator).
@zarfeblong I've worked with these sources in the past. I was able to track down some of the original toolchain and rebuild some of the items.
In particular, I got the one for BBC Micro working, one that never escaped in a shipped product.
