AFAIK, there weren't any formal MIPS architecture standards published for
the early versions of the architecture, though there may have been such
things internally to MIPS. That was not an uncommon practice for computer
architectures; for instance, the formal DEC VAX architecture standard was a
DEC confidential document not available to customers, even though there was
plenty of customer documentation covering most aspects of the architecture.
It might be worth asking on comp.arch.
