Berkeley's funding came (mostly) from ARPA. AT&T provide Unix Edition 6 to many universities after the BSTJ was published in 1977(?) -- Bell Systems Technical Journal. Many thousands of sites had Unix along with Berkeley. Edition 7 and System III were commercially popular, partly because AT&T introduced the binary licensing scheme that allowed VARs, (Microsoft, and SCO come to mind) to port the OS to their brand of hardware. It might have been as late as 1983 before Berkeley versions started getting sold in binary only forms; up until then it was available only in source form, which required a source licence from AT&T which cost non-university sites an arm and a leg ($43K or more). The second Berkeley Unix that I saw (the first that I used) was Ultrix in 1985. Not that I am not gratefull for the Berkeley systems, but some big-name players felt that Unix was more than a "research curiosity". -- -- * * * CFV: net.short.signatures * * *-- Bob Dalgleish Bob_Dalgleish@Develcon.com CompuServe: 70521,2011
