Help identify these obscure operating systems and vendors

Over on the GNU config-patches mailing list, Zack Weinberg is looking for help identifying a number of ancient operating systems and vendors.

These are probably all either vendor or OS names from the late 1980s or early 1990s. Can anyone help me fill out the following list of things that ought to appear in testsuite/, if I knew what to put in place of the question marks?

???-pc533 ???-pc533-???
???-sim ???-sim-???
???-ultra ???-ultra-???
???-unicom ???-unicom-???
???-acis ???-???-aos
???-triton ???-???-sysv3
???-oss ???-???-sysv3
???-storm-chaos ???-???-???

One of them has already been identified – “storm-chaos” turns out to have been added to binutils and/or maybe GCC in 2000, and after some digging around, John Marshall found what it’s referring to: chaos, a hobby operating system for x86 written in C. It has a long history, and after a period of inactivity came back in 2015 with a new website. Some new releases followed, with the last one being version 0.3.0 in 2019. It’s been silence since then.

The others are still up for grabs to be discovered. There is some talk that the pc533 one might be a misspelling of pc532, which would refer to the “NS32K-based PC532 board running NetBSD”. This is an incredibly obscure complete system built around the NS32532, of which only around 150 were built in the early ’90s. However, Weinberg is hesitant to accept this theory without more information, since there is already code to handle the pc532, and he wants to be sure before making any changes.

If there is one place on the internet outside of the GNU mailing lists that might be able to help Weinberg, it’s the OSNews audience. We have so many older people reading OSNews who have been working or otherwise active in this field for many decades, and I wouldn’t be surprised if these cryptic names make some bells ring for some of you.
