It would be interesting to know what RSTS didn't like about that. RSTS will
use floating point if available but does not require it. But it does require a
good emulation of whatever real PDP-11 this device is trying to emulate; RSTS
is known to be more picky than a number of other OS, including RT-11. I've
helped other emulation implementers to fix the missing details that at one time
kept RSTS from running on their creations...
