Primos Ring 0 code nowadays is written in fortran, PLP, SPL, PL1/G,
Modula 2 and PMA (which really counts as 4 or 5 separate instruction
sets -- the Prime machines are microcoded and Prime never throws
anything away so that a Prime machine is actually one of 4 or 5
different possible machines depending on the value of a certain
register which is setable on a per user basis).  Some primos ring 3
routines are written in C.
