The 3900 series systems ran about 38 VUPs and the 780 ran at 1 VUP... -Steve From: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] On Behalf Of Sampsa Laine Sent: Sunday, November 28, 2010 15:54 To: hecnet at Update.UU.SE Subject: Re: [HECnet] SIMH VAX memory weirdness That worked!
