As far as I know, only the (disk) RH11-C uses the extra two bits; The tape RH11 and all other options are unmodified PDP-11 stuff. In my case, I would need to emulate an RH11-C, a Chaosnet, and an IMP interface if possible. Emulating DZ11s as TCP targets as well would be nice, but I have physical DZ11s if there’s not enough capacity left.
