even some IBM content ... in the early 80s, IBM was getting back into support for educational institutions (some gov. restrictions expiring) including forming ACIS starting out with $300M for univ. IBM funded much of univ bitnet network (EARN in europe) ... this mailing list originated on bitnet http://www.garlic.com/~lynn/subnetwork.html#bitnet that used technology similar to that used for internal network http://www.garlic.com/~lynn/subnetwork.html#internalnet IBM & DEC both provided $25M each for MIT's Project Athena which resulted in number of things ... including Kerberos. Circa 2000, there was small company that was selling Kerberos related services, support, etc, CEO was former IBM senior VP of mainframe group. They had contract to port Kerberos to windows what became windows authentication infrastruction. The Unix wars (SUN&AT&T threatening to severely restrict access to Unix) http://www.softpanorama.org/People/Torvalds/Finland_period/unix_wars_and_posix.shtml and http://en.wikipedia.org/wiki/Open_Software_Foundation There was also univ. doing unix work-alikes, UCLA did Locus and CMU doing Mach (besides UCB's BSD). IBM uses Locus for AIX/370 & AIX/386 ... sort of super-SAA in the unix world (supported things like dynamic process migration between distributed systems, even between dissimilar architectures) IBM provided CMU $50M for Andrew stuff .. Camelot (transaction system), MACH (unix work-alike), Andrew Filesystem, Andrew widgets, etc. IBM provides seed funding for Camelot spin-off Transarc ... and then buys Transarc outright. http://www.zois.co.uk/tpm/encina.html MACH unix work-alike ... number of companies start using MACH http://www.cs.cmu.edu/afs/cs.cmu.edu/project/mach/public/www/mach.html when Jobs was "fired" from Apple ... he goes off and does NeXTSTEP which uses MACH as base http://en.wikipedia.org/wiki/NeXTSTEP when Jobs is brought back to Apple ... he brings MACH/NeXSTEP technology back with him (basis for OS X and iOS). -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
