Seller has a (WIP) page documenting the systems these are used in. Suprisingly enough, while they're being phased out and decommissioned by next year, there are some of these DNOS systems still in actual production use.

"decommissioned in 2022 in the UK after 37 years of 24/7 service"

Forgot to mention this earlier, but the documentation Richard supplied is also available on bitsavers.org now in the relevant categories, plus some that Al had on hand but hadn't gotten around to yet. TI stuff listed below. Some of the items would apply to TM990 systems as well. MPP, file io, real time executive, etc.
