More rummaging in the attic about XDS Sigma series: The indexing was unit indexing, i.e. if you were loading words, the index was shifted by two, if halfwords, then shifted by one. I don't recall if this was optional (like the HPPA) or mandatory. Unfortunately, my attic is 8000 miles away at the moment.
