Well, I'm not planning on doing anything particularly serious on it, just thought a "VAX" laptop that boots into CDE would be fun to have..

A faster single core might improve things.

Sure - but I thought a VAXstation 4000/90 got like 40ish VUPS, whilst my relatively recent Core 2 Duo + SIMH only get about 14?
I wonder how much faster say CHARON VAX would be, I gather it's quite thoroughly optimised?

Dell Latitude E6500 (it's a Core 2 Duo at 2.5 GHz I think), running Ubuntu Desktop, Oracle VirtualBox and Ubuntu Server inside the VM, then I run SIMH inside the Ubuntu server - this way the main host OS and the SIMH install can talk to each other over the network.
I get about 7 VUPS on my Mac Mini (a 1.66 GHz Core Duo), so the 14 VUPS is about right, a 2.5 GHz Core 2 is about twice as fast as a 1.6 GHz Core...
