IIRC it's called a 'Princeton Ultra-X'
Thought so. I worked for Princeton at one point, or rather, the company
scooped them up. Inherited a warehouse full of them that they couldn't
get rid on. Put them to reasonable use with Dell SVR4 servers on the
back end. Unfortunately, they code was long in the tooth and full of
bugs even then, so I don't image that they lasted too long.
Used to have the source code, and the TI 34010 dev environment for Sun3.
Undoubtedly gone in one purge or another.

P.S. - Dell SVR4 was an awfully good distro.
