IIRC... Zilog had Zeus (a SYSIII version) running. Exxon Office Systems swallowed and regurgitated Zilog. They were a Vax customer in Princeton in the late '80s. I installed one of the Vax 11/780s with the first RM80 I (and my office) ever saw as a brand new Field Service grunt. The US Internal Revenue Service was looking at replacing (Z8000 systems) them with AT&T sold Pyramid boxes when I was there. Then they swallowed NCR and it all fell apart. This was around '94 or so. AT&T and Siemens were both Pyramid OEMs and were about 50% of Pyramid's business (I was told). Anyone have further info? When Exxon pulled the plug on EOS I thing things were up in the air...
