I'm unaware of any surviving code, but I have tossed some manuals up on my archive.org page for a few 2000's-era releases of the UNIX-RTR Generics for the 5ESS switches of the time. https://archive.org/details/5ess-switch-unix-rtr-operating-system-reference… Unfortunately I haven't secured any code from later UNIX-RTR releases either, just installation and maintenance curricula with some manuals and such thrown in. There is some early MERT stuff bumping around the archive but it predates the BellMAC-32/WE32000 and 3B by several years. - Matt G.
