Al 07/06/12 13:14, En/na Dave McGuire ha escrit: I bet 4.7 would absolutely scream on a 4000-90 if it had CPU support. The difference between 4.7 and 5.0 on a 2.8VUP MicroVAX-III is like night and day...I can only imagine it on a 4000-90, more than ten times faster! -Dave According to this: http://h71000.www7.hp.com/openvms/os/openvms-release-history.html Support for the 4000/90 came in version 5.5-2 (1992). The 3300 was supported in 5.0-2 and the 4000 mod. 2000 in 5.4-2. So none of my real boxen can run 4.7.
