Yes, on bitsavers.  But John's comment reminds me that RSTS-11 V4A doesn't support RL02.  (Only RF11, RK11, RP11.)  V4B may be different, I don't know.

True.  I meant to point out the main difference between RSTS-11 and RSTS/E.  The other difference is that it doesn't require EIS.  Both follow from the fact it was designed for the 11/20.
