Not sure.  The only info I see in s_lock.h is in the "SGI" section:
* This stuff may be supplemented in the future with Masato Kataoka's MIPS-II* assembly from his NECEWS SVR4 port, but
weprobably ought to retain this* for the R3000 chips out there.
 

That name doesn't ring a bell with me --- anyone remember what code is
being referred to here, or where we might find Masato Kataoka?

MIPS-II code may or may not be compatible with Alexander's machine
anyway, but it's the only starting point I see.

Anyway, the last CVS update to port/ultrix.h that appears to have come
from someone actually using Ultrix was rev 1.2 on 7-May-97, which
predates the very existence of s_lock.h as a separate file.  So I'd
definitely advise Alexander to find a tarball from that era and look at
how Ultrix was handled then.

I dunno if we even have tarballs from that far back on-line ... I
suppose another possibility is a date-based pull from the CVS server.
