And yes, > most customers that I knew ran it bare metal. Glad to know that I remembered correctly. In the early 90s I worked teaching multi-vendor Unix courses. One frustration was that AIX on the 370 and AIX on the PS/2 were essentially the same as each other but very different from AIX on the RS/6000 machines. A co-worker and I wrote a short essay about if IBM made cooking equipment: The IBM Industrial Furnace and the IBM camping stove would be almost, but not quite entirely, totally different from the IBM Home Oven. Or something like that.

The opessi.org home page link from Wikipedia just seems to hang. And the files on the SourceForge page are 5 years old. Thanks, Arnold
