The CPU speed makes it slow but imagine it's as fast or faster than a real late model VAX. It's by no means perishingly annoying, it just takes a little thinking between operations. I think I may be spoilt as I've never used a real VAX. It would be interesting to hear of a comparison. The "newer" VAXen are really not that bad. But of course, everything is relative... Some of them are downright zippy. I'll have a VAX 7000 and a 4000-700a on HECnet soon! Zoom! -Dave -- Dave McGuire, AK4HZ New Kensington, PA
