It's been my (unofficial) experience that a VAX usually seems about as fast as an Alpha running at twice the clock rate; so my 4000/96 at 83Mhz or thereabouts is roughly equal to my 3000/600 at 150MHz or thereabouts. Of course, every now and then the Alpha slaps you over the head to let you know that it's really fast. Roger Ivie ivie(a)cc.usu.edu
