I think that VM/CP is the slickest thing I have ever seen. It allows me to bring up test versions of UTS at any time without effecting anyone else. No one should ever attempt operating systems development with anything less.

We're very proud of UTS around here. If anyone is interested in UTS, contact: Cyndy Ainsworth, Mail Stop 208 Amdahl Corporation 1250 E.
