This is a genuine question -- are there non-C-family systems languages from that period (as in languages that allow low level memory manipulation and assembly embedding)? I have never heard of or seen any.

IBM did all their RISC research with PL/8, before creating Aix for their RISC systems thus adopting C instead. IBM i and z mainframes made use of PL/S, C and C++ only came later into the picture as the languages got industry adoption. Xerox PARC initially used BCPL, but quickly followed up with Mesa, then Mesa/Cedar. Wirth was inspired by Mesa to create Modula-2 and then by Mesa/Cedar to create Oberon. Mesa/Cedar designers went to Olivetti and created Modula-2+ and Modula-3. Apple wrote Lisa and initial versions of MacOS in a mix of Pascal and Assembly. VAX used BLISS to develop VMS. PL/I was used by multiple companies, not only by MIT to write Multics. This is just a very brief overview. As for Assembly embedding, it is a language extension not part of ISO C, and was quite common in many languages during the 70 and 80's even some BASIC interpreters had it, like on Acorn computers.
