Don't forget Siemens-Nixdorf was a major reseller of Pyramid OS/x and DC/OSx (SysV R4) and eventually they purchased the remnants of Pyramid after AT&T (a major Pyramid shop and OEM) bought NCR and stopped using/selling Pyramid when DC./OSx was just appearing on the Pyramid MIServer MIPS R3000 boxes.

I know that it didn’t run Unix but I believe Nixdorf Computer was the large computer company at that time.
Both Nixdorf and Siemens were heavy into UNIX.  Both were founders of OSF.   Nixdorf OEM'ed a couple of machines from US firms, as well as making their own.   Siemens and Philips both trended to make their own systems.   IIRC Philips was mostly in the AT&T Camp at the time.  Olivetti was definitely since one of the original 386 systems AT&T tried to sell was their PC (in fact was one of systems ISC used for the original 386 UNIX port - supplied by AT&T).
