I don't think that's the case. OF had its origin in Sun OpenBoot PROM (OBP),
which, ISTR, first
appeared in the SPARCstation 1 (sun4c kernel arch) along with SBus.
Earlier (VME) based SPARC (sun4 kernel arch) systems had only a Sun-3
like boot PROM (single letter commands, no Forth).
Thanks for the clarifications, gentlemen. My first Sun experience was a
SPARC IPC--a bunch of them, actually, in a "freshman engineering lab"...
