Pdp11 RTL/2 Real Time language

I am trying to recover the distribution for RTL/2. We are in the process of restoring a pdp11/23 and check if we can read the disks. Anyone has worked with RTL/2 ?

I did use RTL/2 on RSX11M in the early 80s but I don’t remember much about it other than it is Algol-like but with support for multithreading.

An RSX11M-PLUS distribution of RTL/2 is available on Johnny Billquist’s ROM package site. http://ist.net/rpmpkg
