I tried booting that, and it does boot, but the startup does not run. No system initialization is performed and I login as job 1 with no CCL's defined. The version at https://skn.noip.me/pdp11/rk2.dsk does boot and has all commands installed.

Looking at both environments there are two things I noticed as different from the V06C-03 I was using in high school back in 1978. On our system we had control-T available that was enabled and disabled along with control-R. What was interesting was that it would show the job priority for non-privileged users. Priority display was removed in 7.0 for non-privileged users. We hackers discovered that on a slow running system, one could repeatedly hit control-C during login and abort the change from logged out priority +0 to priority -8 by LOGIN (control-T let us see that we were still at +0). That gave our teacher and the county data center where we rented access to the PDP-11/70 system fits.  Eventually they wrote a "guard" program that would drop the priority of any non-privileged job found to be greater -8. The problem with that check was that some jobs legitimately got bumped to -4 priority temporarily due to the set-special-run-priority syscall. The "guard" did not recognize that and pushed jobs back down to -8.

The other difference I noticed is that SYSTAT in privileged mode does not show the runburst. In privileged mode, SYSTAT had a "Pri/RB" column whereas this V06C-03 only has "Priority". That was documented in the RSTS/E manual I had bought from DEC.

I have to wonder if we were running a version of V06C-03 with those additional enhancements. It definitely was not 7.0. I graduated in June 1980 and I was told they upgraded to 7.0 that summer.
