Yes, but in 1974 that was not an option. I guess the 74-77 version of UNIX
that would have been installed on a PDP 11/40 would have been made for RK05
drives. It would prob be worth the effort to find a version of UNIX 6 for
that media and port to RL02, rather than take a vanilla UNIX 6 and try to
make it work on RL02's and re-solve all of the problems that have already
been solved for the RK05 version. AND the RL02 is larger so moving a
multi-disk UNIX for RK05 disks/partition would not be confined by space.
