OSF design meetings were something of a mashup of locus, project athena, andrew, hp/apollo domain, and (at least) aix distributed filesystem. wiki page http://en.wikipedia.org/wiki/Open_Software_Foundation from above: OSF's standard Unix implementation was known as OSF/1 and was first released in 1992.[2] For the most part, it was a failure; by the time OSF stopped development of OSF/1 in 1994, the only vendor using OSF/1 was Digital, which rebranded it Digital UNIX (later known as Tru64 UNIX after Digital's acquisition by Compaq). ... snip ... during this period ... we were sometimes around the cambridge area, but mostly busy with our ha/cmp product (for aix): http://www.garlic.com/~lynn/subtopic.html#hacmp and this old reference to parallel oracle meeting http://www.garlic.com/~lynn/95.html#13 http://www.garlic.com/~lynn/96.html#15 and these old emails on ha/cmp scaleup http://www.garlic.com/~lynn/lhwemail.html#medusa cmu mach (microkernel) showed up in a number of implementations, including NeXT and the current apple operating system ... recent post: http://www.garlic.com/~lynn/2008b.html#20 folklore indeed and wiki page: http://en.wikipedia.org/wiki/Mach_kernel above has reference to "A comparison of Mach, Amoeba and Chorus" http://www.cdk3.net/oss/Ed2/Comparison.pdf camelot (as encina) was included in the transarc spinoff (along with andrew filesystem) and then directly purchased (joke in previous reference about funding it three different times) ... which has shown up as an aix transaction "cics". wiki page ... http://en.wikipedia.org/wiki/Transarc osf was supposedly alternative to att/sun official "unix". camelot/encina was an alternative to att tuxedo transaction processing (which was spun off and eventually showed up at BEA, recently purchased by oracel). wiki page http://en.wikipedia.org/wiki/Tuxedo_(software) For a totally different mainframe amadeus drift ... in the late 80s, my wife had done a short stint as chief architect of (this) amadeus (which was being done sort of as a european alternative to the united and american mainframe systems) that started off with the old eastern airline res system http://www.amadeus.com/ and wiki page http://en.wikipedia.org/wiki/Amadeus_CRS other mainframe unixes in the 80s was amdahl uts system and the special product done for internal AT&T use, which layered unix interface on top of a stripped down tss/370 kernel. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
