Do you guys know of any Unix workstations that are lesser known than most or made by smaller companies?

Intel 80860-based hardware is quite rare. In addition to VME boards, there have been several workstations designed around it, mostly by japanese companies, such as Kubota (http://web.archive.org/web/2016072923251...80/vistra/) and OKI (http://museum.ipsj.or.jp/en/computer/work/0029.html).
